Complications of osteosynthesis for long-finger metacarpal and phalanx fracture.
Hand surgery & rehabilitation
Fractures of the metacarpals and phalanges represent a significant proportion of hand fractures. Although non-operative treatment is generally effective, some fractures require surgery. Historically, osteosynthesis using K-wires was widely used, but screw plates and then cannulated intramedullary screws have emerged as therapeutic alternatives. We assessed the complications associated with the different osteosynthesis techniques: stiffness, infection, bone consolidation and hardware-related problems. Each osteosynthesis technique has advantages and disadvantages, and choice depends on several factors. An individualized approach according to patient and fracture is essential to optimize clinical results.

Elastic fixation of mallet finger fractures using two K-wires: A case report of a new fixation technique.
Medicine
RATIONALE:Mallet finger fracture is a common sports-related injury that may lead to the tearing of extensor tendon and protrusion of a bony fragment located at the base of the distal phalanx. We affirmed that the elastic fixation of with two K-wires technique is a good method to deal with Mallet Finger fractures that fractures could gain effective fixation than the conventional treatment method and avoid surgical incision complication PATIENT CONCERNS:: We reported a 33-year-old female patient came to our hospital complaining of mild pain, swelling and her right little finger was deformed because of sport's injury. DIAGNOSIS:Acute mallet finger fracture type IV B according to Doyle classification of mallet injuries. INTERVENTIONS:We performed an emergency operation for the elastic fixation of the mallet finger fractures with two K-wires. OUTCOMES:After the surgery, the patient showed functional recovery. No evidence of recurrence was noted 6 months after the operation, and the patient showed no symptoms of sports-related injuries. LESSONS:We discuss the clinical diagnosis, treatment, and follow-up of the patient and suggest that elastic fixation with two K-wires is a good method to treat mallet finger fractures.

Determination of the internal loads experienced by proximal phalanx fracture fixations during rehabilitation exercises.
Frontiers in bioengineering and biotechnology
Phalangeal fractures are common, particularly in younger patients, leading to a large economic burden due to higher incident rates among patients of working age. In traumatic cases where the fracture may be unstable, plate fixation has grown in popularity due to its greater construct rigidity. However, these metal plates have increased reoperation rates due to inflammation of the surrounding soft tissue. To overcome these challenges, a novel osteosynthesis platform, AdhFix, has been developed. This method uses a light-curable polymer that can be shaped around traditional metal screws to create a plate-like structure that has been shown to not induce soft tissue adhesions. However, to effectively evaluate any novel osteosynthesis device, the biomechanical environment must first be understood. In this study, the internal loads in a phalangeal plate osteosynthesis were measured under simulated rehabilitation exercises. In a human hand cadaver study, a plastic plate with known biomechanical properties was used to fix a 3 mm osteotomy and each finger was fully flexed to mimic traditional rehabilitation exercises. The displacements of the bone fragments were tracked with a stereographic camera system and coupled with specimen specific finite element (FE) models to calculate the internal loads in the osteosynthesis. Following this, AdhFix patches were created and monotonically tested under similar conditions to determine survival of the novel technique. The internal bending moment in the osteosynthesis was 6.78 ± 1.62 Nmm and none of the AdhFix patches failed under the monotonic rehabilitation exercises. This study demonstrates a method to calculate the internal loads on an osteosynthesis device during non-load bearing exercises and that the novel AdhFix solution did not fail under traditional rehabilitation protocols in this controlled setting. Further studies are required prior to clinical application.

[Application of radial-lateral forearm free perforator flap on repairing of soft tissue defects in finger].
Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery
OBJECTIVE:To investigate the effectiveness of radial-lateral forearm free perforator flap on repairing of soft tissue defects in the finger. METHODS:Between January 2017 and May 2018, 26 cases of finger skin defects were treated with radial-lateral forearm free perforator flap based on the radial branch of the posterior interosseus artery. There were 21 males and 5 females, with an average age of 26.6 years (range, 19-56 years). The cause of injury included the cutting injury in 16 cases and crush injury in 10 cases. The interval between injury and admission was 30 minutes to 4 hours (mean, 1.5 hours). The injury located at thumb in 6 cases, index finger in 8 cases, middle finger in 6 cases, ring finger in 3 cases, and little finger in 3 cases; and at the dorsum of finger in 6 cases, the lateral side in 6 cases, and the palm in 14 cases. All wounds were accompanied with the tendon and bone exposures, and phalangeal fractures occurred in 10 cases. The size of the defects ranged from 2.0 cm×1.0 cm to 4.0 cm×2.5 cm. And the size of the flap ranged from 2.5 cm×1.5 cm to 4.5 cm×3.0 cm. All wounds at donor sites were sutured directly. RESULTS:All the 26 cases were followed up 4-12 months (mean, 7 months). The 24 flaps survived uneventfully after operation, and the wounds healed by first intention. Partial necrosis occurred at the distal part in 2 flaps, and secondary healing achieved after debridement and dressing. All incisions at donor sites healed by first intention. The appearance and texture of all flaps were satisfactory. The two-point discrimination of the flaps was 5-10 mm (mean, 8 mm) at 4 months after operation. Sensory of the flaps was grade S . Only linear scar was noted at the donor site. CONCLUSION:The radial-lateral forearm free perforator flap in repairing of the soft tissues in finger can shorten the disease duration, reduce the damage of the donor site, and improve the patients' quality of life.

Metacarpophalangeal Joint Reconstruction of a Complex Hand Injury with a Vascularized Lateral Femoral Condyle Flap Using an Individualized 3D Printed Model-A Case Report.
Journal of personalized medicine
This case report describes the surgical management of a patient with a complex hand trauma. This injury included tendon, vascular, and nerve injuries, a partial amputation of the index finger, fractures of the third proximal phalanx, and destruction of the metacarpophalangeal joint of the fifth finger. Firstly, the acute treatment of a complex hand injury is described. Secondly, the planning and execution of a joint reconstruction using a vascularized lateral femoral condylar flap, assisted by an individual 3D model, is illustrated. Precise reconstruction of the affected structures resulted in good revascularization as well as an anatomical bone consolidation. Intensive physical therapy, including autonomous proprioceptive range-of-motion exercises by the patient, resulted in significant functional improvement of the hand in daily life. Overall, we report on the successful reconstruction of a metacarpophalangeal joint by using a vascularized flap from the lateral femoral condyle. Furthermore, this case report highlights the efficacy of integrating individualized 3D printing technology to plan complex reconstructions, opening up promising opportunities for personalized and optimized interventions.

Chronic post-traumatic volar plate avulsions of the finger proximal interphalangeal joint: A literature review of different surgical techniques.
Caviglia Daniele,Ciolli Gianluca,Fulchignoni Camillo,Rocchi Lorenzo
Orthopedic reviews
Avulsions of the volar plate of the finger proximal interphalangeal joint (PIPJ) following sprains are often undiagnosed in the acute setting. Therefore, the chronic outcomes of this injury are most frequently the object of study and treatment. Different techniques for volar plate chronic avulsion repair are described in the literature. The most used among these are mainly two: the direct suturing with or without the use of bone anchors and the tenodesis techniques with flexor digitalis superficialis (FDS). The aim of this systematic review is to determine outcomes and complications associated with these surgical treatments of post-traumatic volar plate avulsions without phalangeal fractures. An electronic literature research was carried out and pertinent articles were selected. Surgical techniques details, outcomes and complications for direct sutures and tenodesis technique are discussed. Outcomes (Range of motion and pain) seem to be comparable, whereas authors that use the direct suture technique describe more frequently PIPJ flexion contracture complication. From this review of the literature, authors believe that both techniques are available for the repair of chronic injuries of the volar plate of the PIPJ, although direct suturing can be considered as less reproducible.

Choosing the proper implant for extra-articular fractures of proximal phalanges: A study on 75 cases.
Injury
INTRODUCTION:Phalangeal fractures are the most common fractures of the hand and in particular the proximal phalanx of the long fingers is the most involved. These fractures can ben conservatively managed but, when the fracture pattern is considered unstable, surgical treatment is recommended. However, there is no consensus in literature about the proper surgical option for extra-articular proximal phalanx fractures. MATERIAL AND METHODS:We compared clinical and radiographical results after treatment of 75 cases of extra-articular proximal phalanx fractures using three different surgical techniques: closed reduction and internal fixation (CRIF) with Kirschner wires (G1 group), open reduction internal fixation (ORIF) with plates and screws or lag screws (G2 group), and closed reduction and intramedullary screw fixation (CRIMEF)(G3 group). RESULTS:We found no significant differences in term of union rate and time to fracture healing between the three groups. However, we found a significant reduction in time to return at work and in TAM at the final follow-up examination in G3 group (treated with CRIMEF) when compared with both G1 and G2. No differences in complications rate were found between three groups. DISCUSSION:The surgical variability in the management of extra-articular phalanx fractures create lacks on standard guide for treatment. CONCLUSIONS:In conclusion, our results showed good clinical and radiographical results with all the three surgical options. However, the closed reduction and internal fixation with intramedullary screws (CRIMEF) seems to be better in terms of time to return to work and TAM at the final follow-up, probably due to good primary stability and little risk of soft tissue adherence development.

The Wire Study-a protocol for a multi-stage feasibility study evaluating K-wire fixation of hand fractures in the UK.
Pilot and feasibility studies
BACKGROUND:Hand fractures are common and sometimes require surgery to restore function. Placement of Kirschner wires (K-wires) is the most common form of surgical fixation. After placement, a key decision is whether to bury the end of a K-wire or leave it protruding from the skin (exposed). A recent systematic review found no evidence to support either approach and a national clinician and surgeon survey demonstrated further uncertainty. We aim to determine the design of a definitive randomised controlled trial assessing the cost and clinical effectiveness of buried versus exposed Kirschner wires for adults with metacarpal or phalangeal fractures. METHODS:We will employ three methodologies: a national service evaluation of current clinical practice, patient and surgeon focus groups and a consensus meeting to finalise the protocol for a randomised controlled trial. For the service evaluation, all outcomes will be summarised using descriptive statistics overall and split by group (buried versus exposed K-wires). Information collected in the patient focus groups will be analysed thematically. The surgeon consensus meeting will address each part of the design in turn and through discussion agree a final protocol. DISCUSSION:The study may be monitored, or audited in accordance with the current approved protocol, Good Clinical Practice (GCP), relevant regulations and standard operating procedures. The Chief Investigator will submit and, where necessary, obtain approval from the above parties for all substantial amendments to the original approved documents. A feasibility study report will be published by the Wire Study Steering committee. Additional members of the steering group and citable collaborators will be listed within the manuscript and their roles identified.

Comparing the diagnostic performance of radiation dose-equivalent radiography, multi-detector computed tomography and cone beam computed tomography for finger fractures - A phantom study.
PloS one
PURPOSE:To compare the diagnostic performance and raters´confidence of radiography, radiography equivalent dose multi-detector computed tomography (RED-MDCT) and radiography equivalent dose cone beam computed tomography (RED-CBCT) for finger fractures. METHODS:Fractures were inflicted artificially and randomly to 10 cadaveric hands of body donors. Radiography as well as RED-MDCT and RED-CBCT imaging were performed at dose settings equivalent to radiography. Images were de-identified and analyzed by three radiologists regarding finger fractures, joint involvement and confidence with their findings. Reference standard was consensus reading by two radiologists of the fracturing protocol and high-dose multi-detector computed tomography (MDCT) images. Sensitivity and specificity were calculated and compared with Cochrane´s Q and post hoc analysis. Rater´s confidence was calculated with Friedman Test and post hoc Nemenyi Test. RESULTS:Rater´s confidence, inter-rater correlation, specificity for fractures and joint involvement were higher in RED-MDCT and RED-CBCT compared to radiography. No differences between the modalities were found regarding sensitivity. CONCLUSION:In this phantom study, radiography equivalent dose computed tomography (RED-CT) demonstrates a partly higher diagnostic accuracy than radiography. Implementing RED-CT in the diagnostic work-up of finger fractures could improve diagnostics, support correct classification and adequate treatment. Clinical studies should be performed to confirm these preliminary results.

Dynavisc as an Adhesion Barrier in Finger Phalangeal Plate Fixation-a Prospective Case Series of 8 Patients.
Journal of hand surgery global online
Purpose:Adhesion problems are common after plate fixation of finger phalanges and often lead to stiffness and reoperations with plate removal and tenolysis. The aim of this prospective case series was to study the effect of the adhesion barrier gel Dynavisc on total active motion (TAM), postoperative pain, and grip strength after plate fixation of phalangeal fractures. Total active motion at 3 months after surgery was the primary outcome. Methods:Eight patients with a fracture of the proximal phalanx underwent surgery with open reduction and plate fixation. The adhesion barrier Dynavisc was applied between plate and extensor tendon and between tendon and skin. Results in terms of pain, grip strength, and TAM at 2 weeks, 3 months, and 1 year after surgery were collected. Results on TAM were classified according to Page and Stern. Results:After 3 months, only 2 patients had a result classified as excellent. After 1 year, 3 patients fulfilled the criteria for an excellent result. There were no adverse events. Patients with long-standing postoperative pain had a worse outcome on TAM. Conclusions:The antiadhesive effect of Dynavisc in this prospective case series was unconvincing. Only 2 patients had an excellent result on TAM at 3 months. Because the gel is resorbed within 30 days after application, it is questionable whether the gel had a role in improvement that occurred later in the postoperative course. Larger, randomized studies would be required to show any anti-adherent effect of Dynavisc definitively in finger fracture surgery. Type of study/level of evidence:Therapeutic IV.

Cost-effectiveness of introducing cone-beam computed tomography (CBCT) in the management of complex phalangeal fractures: economic simulation.
Musculoskeletal surgery
PURPOSE:The purpose of this study was to evaluate the cost-effectiveness of introducing cone-beam computed tomography (CBCT) in the management of the complex finger fractures with articular involvement. METHODS:We created a decision tree model simulating the diagnostic pathway of complex finger fractures, suggesting the use of CBCT as alternative to multi-slice computed tomography (MSCT), and we compared their clinical outcomes, costs, and cost-effectiveness for a hypothetical cohort of 10,000 patients. Measures of effectiveness are analysed by using quality-adjusted life years, incremental cost-effectiveness ratio, and net monetary benefit. RESULTS:Diagnosis of a complex finger fracture performed with CBCT costed 67.33€ per patient, yielded 9.08 quality-adjusted life years, and gained an incremental cost-effectiveness ratio of 29.94€ and a net monetary benefit of 9.07 € at 30,000€ threshold. Using MSCT for diagnosis costed 106.23 €, yielded 8.18 quality-adjusted life years, and gained an incremental cost-effectiveness ratio of 371.15 € and a net monetary benefit of 8.09 €. CBCT strategy dominated the MSCT strategy. The acceptability curve shows that there is 98% probability of CBCT being the optimal strategy at 30,000€ threshold (1 EUR equal to 1.11 USD; updated on 02/02/2020). CONCLUSION:CBCT in complex finger fractures management is cost saving compared with MSCT and may be considered a valuable imaging tool in preoperative assessment, allowing early detection and appropriate treatment. It shortens the time to completion of diagnostic work-up, reduces the number of additional diagnostic procedures, improves quality of life, and may reduce costs in a societal perspective.

Scheduled Emergency Trauma Operation: The Green Line Orthopedic Trauma Surgery Process Of Care.
Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society
BACKGROUND AND AIMS:Traditionally, patients requiring an orthopedic emergency operation were admitted to an inpatient ward to await surgery. This often led to congestion of wards and operation rooms while, for less urgent traumas, the time spent waiting for the operation often became unacceptably long. The purpose of this study was to evaluate the flow of patients coded green in a traffic light-based coding process aimed at decreasing the burden on wards and enabling a scheduled emergency operation in Central Finland Hospital. MATERIALS AND METHODS:Operation urgency was divided into three categories: green (>48 h), yellow (8-48 h), and red (<8 h). Patients, who had sustained an orthopedic trauma requiring surgery, but not inpatient care (green), were assigned an operation via green line process. They were discharged until the operation, which was scheduled to take place during office hours. RESULTS:Between January 2010 and April 2015, 1830 green line process operations and 5838 inpatient emergency operations were performed. The most common green line process diagnoses were distal radial fracture (15.4% of green line process), (postoperative) complications (7.7%), and finger fractures (4.9%). The most common inpatient emergency operation diagnosis was hip fracture (24.3%). Green line process and inpatient emergency operation patients differed in age, physical status, diagnoses, and surgical procedures. CONCLUSION:The system was found to be a safe and effective method of implementing orthopedic trauma care. It has the potential to release operation room time for more urgent surgery, shorten the time spent in hospital, and reduce the need to operate outside normal office hours.

Nonarticular Base and Shaft Fractures of Children's Fingers: Are Follow-up X-rays Needed? Retrospective Study of Conservatively Treated Proximal and Middle Phalangeal Fractures.
Vonlanthen Janine,Weber Daniel M,Seiler Michelle
Journal of pediatric orthopedics
BACKGROUND:Phalangeal fractures of the hand are common in children, and most extra-articular fractures can be treated with nonoperative management. Minimally or nondisplaced fractures may simply be immobilized, whereas displaced fractures need closed reduction before immobilization. Although few of these fractures displace secondarily, most schemes currently recommend follow-up x-rays after initial diagnosis. Our primary objective was to identify subgroups of finger fractures that are stable, thus requiring no radiographic monitoring. METHODS:This study was designed as a retrospective, single-center analysis of conservatively treated pediatric finger fractures of the proximal and middle phalanges. We included patients up to 16 years with base or shaft fractures of the index to little fingers who underwent nonoperative treatment and standardized follow-up controls in our pediatric hand surgery outpatients' clinic between 2010 and 2016. Fracture angular deformity in x-rays taken at diagnosis and after 1 and 3 weeks were reassessed blinded, and a statistical analysis was conducted to identify fracture types that are prone to secondary angular deformity. RESULTS:A total of 478 patients were eligible; 113 were lost due to missing final radiographic controls. Overall, 365 patients were analyzed; they had a mean age of 9.7 years (range, 1 to 16), and 33.4% required a primary closed reduction. A secondary angular deformity occurred in 2.2% (8/365) of all finger fractures. No secondary angulation occurred in primary minimally and nondisplaced fractures, but 6.6% (8/122) of the reduced fractures showed a subsequent loss of reduction. CONCLUSIONS:Minimally angulated (<10 degrees) and nondisplaced metaphyseal and diaphyseal fractures of proximal and middle phalanges of the index to little fingers are stable and therefore do not need radiographic follow-ups. However, initially angulated fractures requiring closed reduction bear a risk of subsequent loss of reduction. LEVEL OF EVIDENCE:Level III-retrospective study.

Buddy taping versus splint immobilization for paediatric finger fractures: a randomized controlled trial.
Weber Daniel M,Seiler Michelle,Subotic Ulrike,Kalisch Markus,Weil Robert
The Journal of hand surgery, European volume
The purpose of this single-centre randomized controlled trial was to assess the non-inferiority of buddy taping versus splint immobilization of extra-articular paediatric finger fractures. Secondary fracture displacement was the primary outcome; patient comfort, cost and range of finger motion were secondary outcomes. Ninety-nine children were randomly assigned to taping or splinting. Sixty-nine fractures were undisplaced; 31 were displaced and required reduction before taping or splinting. Secondary displacement occurred in one patient in the taping and three in the splinting group. The risk difference was below the predefined non-inferiority level of 5%. All secondary displacements occurred in the 31 displaced fractures after reduction and were in little fingers. Patient comfort was significantly higher and cost lower in the taping group. We conclude from this study the non-inferiority of buddy taping versus splint immobilization of extra-articular paediatric finger fractures in general. We advise treatment may need to be individualized for patients with displaced fractures because we cannot make any absolute conclusions for these fractures. I.

A Comparison of 30-Day Perioperative Complications for Open Operative Care of Distal Upper-Extremity Fractures Treated by Orthopedic Versus Plastic Surgeons: A Study of the National Surgical Quality Improvement (NSQIP) Database.
Journal of hand surgery global online
Purpose:To determine whether surgeon specialty affects complications after open operative care of distal upper-extremity fractures. Methods:We performed a retrospective cross-sectional study using the American College of Surgeons National Surgical Quality Improvement Database from 2005 to 2016. Patients were included if they received open operative treatment by an orthopedic or a plastic surgeon for distal radius/ulna, carpal, metacarpal, or phalangeal fracture. Univariate analysis and multivariable analysis of perioperative complications were performed to identify differences between the 2 specialties. Major complications assessed were 30-day reoperation and mortality. We also assessed transfusion, thromboembolic, surgical site infections, cardiac, pulmonary, and renal complications. Results:A total of 20,512 patients were included. Most cases performed by orthopedic surgeons (71.2%) were for distal radius/ulna fractures, whereas the majority of cases performed by plastic surgeons were for metacarpal (41.0%) and phalangeal (37.9%) fractures. No difference was identified in most perioperative complications between specialties. Plastic surgeons had a higher incidence of surgical site infections (1.2% vs 0.5%) on univariate analysis. However, when controlling for variables such as patient demographics and comorbidities in multivariable analysis, surgical specialty was not significantly associated with surgical site infection. Rather, surgery on phalangeal bones (adjusted odds ratio [aOR] = 2.745; 95% confidence interval [CI], 1.559-4.833), higher wound class (wound class 3 aOR = 3.630; 95% CI, 2.003-6.577), and smoking (aOR = 1.970; 95% CI, 1.279-3.032) were independent risk factors for surgical site infection. Plastic surgeons were found to operate on proportionally more smokers, patients with higher wound class, and phalangeal fractures (37.9% of all fracture cases) compared with orthopedic surgeons. Conclusions:Orthopedic and plastic surgeons achieve equivalent outcomes from a safety perspective after open operative treatment of upper-extremity fractures in terms of mortality and 30-day reoperation, which suggests that both specialties can safely perform call-related operative upper-extremity fracture care. Plastic surgeons operated on more smokers, patients with higher wound class, and phalangeal fractures, all of which were associated with increased incidence of surgical site infection, revealing differences in practice composition from their orthopedic colleagues. Type of study/level of evidence:Therapeutic III.

Buddy taping after reduction of displaced extra-articular phalangeal finger fractures in children: a randomized controlled trial.
The Journal of hand surgery, European volume
In this randomized controlled trial, we assessed the non-inferiority of buddy taping to splinting after reduction of displaced extra-articular proximal and middle phalangeal finger fractures in children. The primary outcome was the rate of secondary fracture displacements; the secondary outcomes were patient comfort, analgesic efficacy and total range of active motion 6 months after injury. Eighty-one patients participated: 43 with taping and 38 with splinting. Secondary displacement occurred in eight patients: five in the splinting group and three in the taping group. Risk difference was below the predefined non-inferiority of 10%. Patient comfort was significantly higher in the taping group, with no group differences for other parameters. Our previous study recommended taping for undisplaced finger fractures in children. With the current data, we recommend taping these finger fractures irrespective of displacement or need for reduction. We are encouraged to propose taping as an alternative to splinting for increased patient comfort, lower cost, and shorter application time. I.

BMC musculoskeletal disorders
BACKGROUND:Distal Phalanx (DP) fractures are the most common hand injuries. Bone fixation associated with soft tissue reconstruction, is often required to ensure more effective outcomes. The aim of the present study is to compare functional outcomes of DP fractures surgically treated with crossed manual drilled 23 Gauge needles vs crossed Kirschner-wires (k-wire). METHODS:Clinical data included analysis of patient demographics, range of motion (ROM), and complications. Radiographic assessment considered fracture type, location, fracture displacement, and radiographic union. Functional outcomes analysis was performed.The statistical significance was assessed at the level of probability lower than 5%. RESULTS:A total of 60 patients from 2012 to 2015 were retrospectively enrolled and among them 12 patients suffering from diabetes or current smokers. A total of 60 DP fractures were treated, 32 with needles (group A) and 28 with k-wire fixation (group B). Time to union, showed in different time points, was significantly lower in group A (≤ 40 days, p = 0.023*) compared to group B. ROM of the distal interphalangeal joint at six months follow-up was 60° in group A and 40° in group B. A significant improvement was observed (p = 0.001*) in the 23 G needle treated group. Functional outcome analysis showed that VAS was significantly lower in group A compared to group B (p = 0.023*). CONCLUSION:Our study showed that the 23 G needle yielded satisfactory results in terms of time to union and range of motion compared to k-wire fixation especially for tuft and shaft DP fractures. Therefore, should be a valid alternative to k-wire fixation in selected patients.

Hand Surgical Operating Room Size Allocation: A Comparative Space Utilisation Study.
The journal of hand surgery Asian-Pacific volume
This study evaluated operating room (OR) space required for various hand surgical procedures. We analysed the size requirements for hand surgical cases divided into four settings: (1) large OR setting requiring fluoroscopy and microsurgical equipment, (2) medium-sized OR setting for cases requiring fluoroscopy, (3) smaller OR setting and (4) minor procedural room without anaesthesia with the aim to describe room size requirements for hand surgery practices. A variety of hand surgical cases were selected: large cases (microvascular digit replantation), medium-sized cases (closed reduction percutaneous pinning [CRPP] of phalangeal fractures) and smaller cases (carpal tunnel release [CTR]) with and without anaesthesia. Space requirements were compared to general surgery cases (laparoscopic appendectomy) and general orthopaedic surgery cases (cephalomedullary nail [CMN]). Necessary operative equipment was measured (ft) to calculate requirements for each procedure. Large hand cases such as digit replantation necessitated the most OR space (125 ft), followed by general orthopaedic cases (CMN; 118 ft), medium-sized hand cases (CRPP phalanx; 107 ft), general surgery laparoscopic appendectomy (68 ft), small hand cases (CTR; 85 ft) and minor procedures (49 ft). Hand procedures can be divided into major procedures requiring significant OR space (125 ft), medium procedures in standard OR suites (107 ft), procedures in small ORs with anaesthesia (81 ft) or office-based setting without anaesthesia (49 ft). These findings help define space utilisation for hand procedures and may have practical implications related to efficiency, cost and patient safety in the hospital and outpatient setting.

A New Normal: Trends of Upper Extremity Orthopaedic Injuries Nationwide During the COVID-19 Pandemic.
Cureus
Background The widespread societal effects of the COVID-19 pandemic connote public health and epidemiological changes for orthopedic injuries. The epidemiology of upper extremity injuries and the effects of the pandemic on these nationwide trends is poorly defined. Methods This cross-sectional, descriptive epidemiological study compares epidemiological trends among upper extremity (UE) orthopedic injuries presenting to emergency departments (EDs) prior to and during the COVID-19 pandemic. Upper extremity fracture and dislocation data was sourced from the National Electronic Injury Surveillance System (NEISS) database in years prior to (2015-2019) and during the pandemic (2020-2021). Data on incidence, patient demographics, injury patterns, mechanisms of injury, incident locale, and patient disposition were collected and compared between years. Results The pre-COVID-19 incidence rate (IR) of UE fractures at 2.03 per 1,000 persons (n=3038930 from 2015-2019) decreased to 1.84 per 1,000 in 2020 (n=474805) and 1.82 per 1,000 in 2021 (n=471793). Dislocation rates were largely unchanged at 0.34 per 1,000 people (n=476740) prior to the pandemic and with incidence rates of 0.33 per 1,000 (n=85582) and 0.34 per 1,000 (n=89386) in 2020 and 2021, respectively. Female patients over 65 had the highest injury IR at 4.85 per 1,000 (n=976948). Finger fractures (IR=0.38 per 1000, n=96009) overtook hand fractures (IR=0.51 per 1000, n=310710) as more common during COVID-19 in males, while wrist (IR=0.55 per 1000, n=350650) fractures remained most common in females. Injuries from individual sports, such as skateboarding and bicycling, increased during the pandemic, while injuries from team sports decreased. Hospital admission and observation increased in 2020, while discharge and transfer rates decreased. Admission, observation, and discharge rates moved closer to pre-pandemic levels in 2021. Conclusions The COVID-19 pandemic was associated with epidemiological and activity changes regarding UE fractures and dislocations presenting to EDs. The present study demonstrates notable decreases in rates of upper extremity fractures and dislocations, increases in rates of injuries related to outdoor and individual sports such as skateboarding with corresponding decreases in rates of injuries related to organized sports such as basketball, increases in the rates of injuries occurring in homes and in association with pet supplies, and decreases in rates of injuries occurring in schools and places of recreation observed during the pandemic. Additionally, trends observed among patient disposition specific to the pandemic, such as increasing rates of patient admission, observation, and against medical advice (AMA) departure with decreasing rates of discharge and transfer, offer insight into the burden of upper extremity injuries on the healthcare system during this critical time. While upper extremity orthopedic injuries remained common through the pandemic, the early pandemic was associated with higher rates of hospital admission that normalized closer to pre-pandemic levels by 2021, which may herald a shift and return to pre-pandemic trends. Future research will determine the long-term downstream effects of COVID-19 on activity-related orthopedic injuries and bone health.

Introduction and objective The fracture of hand bones is very common among manual hand workers and a fractured hand imparts a great effect on a person's productivity both socioeconomically and from a body image point of view. The most common method of hand fractures fixation is with the help of Kirschner wires. Kirchner wires can be inserted in exposed or in buried manner. There are a few studies that provide a comparative analysis of rate of infection between these two techniques. This study aimed to assess the rate of infection in buried versus exposed Kirschner (K)-wires for hand fractures. Material and method The study was designed as a randomized controlled trial with consecutive non-random sampling. It was conducted in the Department of Plastic Surgery, Holy Family Hospital, Rawalpindi, Pakistan, and lasted from June to December 2019. Blinding was not possible as both the operating surgeon and patient were aware of the procedure being done; however, the assessor was blinded and was not aware which group got which treatment. Total 122 patients with fractures of metacarpals and phalanges of hand were included in the study and were divided into two groups with 61 patients in each. Group A was treated with buried K-wires and group B with exposed K-wires. The patients were followed for one month for the outcomes in terms of infection in the patients. Results Group A had 24 females (39.3%) and 37 males (60.7%). Group B had 16 females (26.2%) and 45 males (73.8%). In group A, nine (14.8%) patients had ages between 10 and 20 years, 18 (29.5%) patients between 21 and 30 years, 14 (23.0%) patients between 31 and 40 years, 11 (18.0%) patients between 41 and 50 years, and nine (14.8%) were between 51 and 60 years. The mean duration of surgery was 35.16 minutes for group A and 27.30 minutes for group B. Based on modified Oppenheim scoring system for pin site infection, out of 61 patients, seven (11.5%) with buried K-wires while 14 (23%) with exposed K-wires developed pin site infection. Conclusion Rate of infection is low in buried K-wires as compared to exposed K-wires though not statistically significant (p>0.05) for the fractures of metacarpals and phalangeal fractures of hand.

Clinical outcomes of unstable metacarpal and phalangeal fractures treated with a locking plate system: a prospective study.
Katayama Takeshi,Furuta Kazuhiko,Ono Hiroshi,Omokawa Shohei
The Journal of hand surgery, European volume
We prospectively assessed clinical and radiological outcomes of locking plate fixation in treating unstable fractures in 11 metacarpals, 15 proximal phalanges, and eight middle phalanges in 34 consecutive patients from October 2011 to December 2016. Median length of follow-up was 14 months (range 12-24). The motion of finger joints, bony union, and complication rates were recorded. The median postoperative range of motion of the two interphalangeal joints and the metacarpophalangeal joint was 82% of the contralateral hands. Fractures in the three locations had significantly different recovery of the finger motion, with the best recovery for the metacarpal fractures. Closer distance between the plate edge and joint line was associated with a more limited range of the finger motion. The clinical outcomes approached an acceptable level at final follow-up. Finger stiffness is unavoidable after locking plate fixation of metacarpal and phalangeal fractures even with early hand therapy, with stiffness occurring in 10 out of 34 cases at the time of final follow-up 1 year after surgery.

Evaluating Kirschner wire fixation versus titanium plating and screws for unstable phalangeal fractures: A systematic review and meta-analysis of postoperative outcomes.
Journal of hand and microsurgery
Background:Unstable phalangeal fractures represent a clinical challenge in hand surgery. The choice of fixation method, whether Kirschner wire (K-wire) fixation or titanium plating with screws, often depends on surgeon preference due to the lack of comprehensive comparative data. This article aimed to compare the postoperative outcomes of K-wire fixation versus titanium plating and screws in the treatment of unstable phalangeal fractures. Methods:This review was conducted according to the PRISMA guidelines for reporting systematic reviews and meta-analyses. A systematic review and meta-analysis of the existing literature was done encompassing PUBMED, EMBASE, Google Scholar, and Cochrane library using the keywords: "K wire/ Kirschner wire", "titanium plate/ screws", "Miniplate/ screws", and "Unstable phalan∗ fracture/ hand fracture". Results:After screening 2374 articles, 6 final studies with a total of 414 patients were included. Operative time was significantly shorter with K-wire fixation compared to plating, by a mean difference of -27.03 min [95% CI -43.80, -10.26] (p = 0.02). Time to radiographic union averaged 7.43 weeks with K-wires versus 8.21 weeks with titanium plates. No statistically significant differences emerged between groups for overall complications (p = 0.69), infection (p = 0.47), malunion (p = 0.36), stiffness (p = 0.11), or need for reoperation (p = 0.10). Conclusion:K-wire fixation demonstrated shorter mean operating time and faster radiographic union versus plating for unstable phalangeal fractures. These findings can guide surgical decisions and emphasize the need for individualized treatment based on fracture type and patient factors.

Hand and Wrist Injuries Related to Motocross Injuries: 5 Year Series.
Singh Rohit,Chojnowski Adrian,Hay Stuart
The journal of hand surgery Asian-Pacific volume
BACKGROUND:The increasingly fashionable sport of motocross is practiced worldwide by millions of people, but there is very little in the literature regarding its associated injuries and their prevention. We therefore present the first comprehensive, prospective study looking at hand and wrist injuries resulting from motocross injuries in the UK. METHODS:Data was prospectively collected over a 5-year period (from 2010 to 2015) at our regional trauma unit. We exclusively looked at motocross riders. Injuries sustained via motorcycle were excluded from our study. RESULTS:During the period studied (five years), 615 injuries were collected, including 240 patients with 265 hand and wrist injuries. Most of injuries were sustained in male patients. The patient's age range was from 4-78 years with most injuries occurring during the spring and summer months. A total of 96 (40%) patients required operative treatment. The most common injury pattern was distal radius fractures (n = 53, 20%), followed by metacarpal fractures (n = 38, 14%) and phalangeal fractures (n = 36, 13.5%). CONCLUSIONS:This study shows the impact and incidence of related hand and wrist injuries. Motocross is a globally fashionable sport. This study shows that the number of annual tournaments and racers have doubled in last 5 years. The number of hand and wrist related injuries and operative requirements have quadruples over the last five years. It is recognized as a high-risk sport despite the use of protective equipment and course adaptions. These injuries can have implications for nearby treating hospitals.

Comparative study of K-wire combined with screw vs. K-wire in the treatment of AO type B3.1 phalangeal fractures.
BMC musculoskeletal disorders
PURPOSE:The purpose of this study was to introduce the surgical method of K-wire combined with screw in the treatment of Arbeitsgemeinschaftfür Osteosynthesefragen (AO) type B3.1 phalangeal fractures and to compare its clinical, radiological and functional outcomes with K-wire fixation. METHODS:This was a retrospective comparative study. From January 2015 to February 2022, we treated 86 patients with AO type B3.1 phalangeal fractures. A total of 71 patients were finally included in the statistical analysis. Thirty-nine patients received K-wires combined with screw, and 32 patients received simple K-wires. The follow-up time was at least 6 months. Outcome measures included general information, operative time, total active motion (TAM), pinch strength, radiological union time, pain assessed by visual analog scale (VAS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, cost, and complications. RESULTS:The follow-up time was 6-12 months, with an average of 7.9 months. All patients achieved clinical and radiological union. Compared with the K-wire fixation group, the TAM, radiological union time and VAS score of the K-wire combined with screw group had obvious advantages. Compared with the opposite healthy hand, the grip strength of the two groups was similar, and there was no significant difference in the QuickDASH score. The incidence rate of complications in the K-wire combined with screw group (2/39) was lower than that in the K-wire fixation group (7/32). CONCLUSIONS:Compared with simple K-wire fixation, K-wire combined with screw in the treatment of AO type B3.1 phalangeal fractures is a safer and reliable surgical method. K-wire controls the rotation and plays a role similar to a "lock". The screw can exert pressure and fix it more firmly. It shortens the time of fracture healing and has a higher TAM and fewer postoperative complications.

Phalangeal fractures: A retrospective comparison of open reduction and internal fixation vs. closed reduction and percutaneous pinning.
Journal of hand and microsurgery
The treatment of phalangeal fractures is guided by fracture characteristics, patient factors and surgeon judgment. This study retrospectively compares characteristics of phalangeal fractures treated with closed reduction percutaneous pinning (CRPP) with those of fractures treated with open reduction internal fixation (ORIF) to identify risk factors associated with reoperation. A total of 901 phalangeal fractures were included and treated operatively by either CRPP (748 fractures, 83 %) or ORIF (153 fractures, 17 %). Demographics, surgical management, and complication data were collected. Statistical analyses were performed to stratify risk associations and identify potential predictors of reoperation. With multivariate analysis and bootstrapped LASSO regression, fractures addressed by means of ORIF (vs. CRPP), work-related fractures, and open fractures were found to be independently associated with reoperation. These findings can be used to guide patient selection, surgical planning and timing of fracture repair. Level of evidence:Level III, Therapeutic.

'It's just a finger isn't it…': patients' perspectives of recovery following finger fractures and participation in surgical trials - a qualitative interview study.
BMJ open
OBJECTIVES:To (1) generate detailed, person-centred data about the experience of finger injury and treatment and (2) understand the patients' perspectives of research involvement with a view to informing better designed future studies in hand injury. DESIGN:Qualitative study using semistructured interviews and framework analysis. PARTICIPANTS:19 participants who were part of the Cohort study of Patients' Outcomes for Finger Fractures and Joint Injuries study in a single secondary care centre in the UK. RESULTS:The results of this study showed that although finger injuries are frequently seen as minor by patients and healthcare professionals, their effects on peoples' lives are possibly greater than first anticipated. The relative importance of hand functioning means that the experience of treatment and recovery varies and is shaped by an individual's age, job, lifestyle and hobbies. These factors will also inform an individual's perspective on and willingness to participate in, hand research. Interviewees showed reluctance to accept randomisation in surgical trials. Interviewees would be more likely to participate in a study testing two variants of the same treatment modality (eg, surgery vs surgery), rather than two different modalities, (eg, surgery vs splint). The Patient-Reported Outcome Measure questionnaires that were used in this study were seen as less relevant by these patients. Pain, hand function and cosmetic appearance were considered important, meaningful outcomes. CONCLUSIONS:Patients with finger injuries need more support from healthcare professionals as they may experience more problems than first anticipated. Good communication by clinicians and empathy can help patients engage with the treatment pathway. Perceptions of an 'insignificant' injury and/or need for quick functional recovery will influence recruitment to future hand research (both positively and negatively). Accessible information about the functional and clinical consequences of a hand injury will be important in enabling participants to make fully informed decisions about participation.

Early Functional Treatment of Proximal Phalanx Fractures in Children: A Case Series Study.
Pediatric emergency care
OBJECTIVES:The objective of this study was to assess proper indications a nonsurgical treatment regime for pediatric fractures of the proximal phalanx based on principles of early functional treatment. METHODS:A case series (evidence level 4) of 30 pediatric patients with fractures of the proximal phalanx were treated nonsurgically using protective dynamic splinting techniques and fiberglass casting material. Assessments were performed clinically and by x-ray within 4 to 8 weeks of commencement of treatment. Outcome measures included Disabilities of the Arm, Shoulder, and Hand score questionnaire as well as fingertip palm distance (cm) and dynamic pain interval assessments. RESULTS:All fractures healed without any clinically apparent bony deformities. Disabilities of the Arm, Shoulder, and Hand scores were of 25.17 ± 5.29 (mean ± SD), which indicated good functional results usually within 2 weeks of removal of dynamic splints. Fingertip palm distance measurements at endpoints were of 0.17 ± 0.27 cm (mean ± SD), which indicated an almost free range of finger motion. Absence of pain perception under active finger motion (dynamic pain interval) was noted at 14.10 ± 6.79 days (mean ± SD). CONCLUSIONS:Well-established criteria for surgical treatment of phalangeal fractures exist. However, in our experience, a majority of pediatric fractures of the proximal phalanx can be safely treated nonsurgically with dynamic splinting along with shorter intervals of immobilization of the affected fingers and faster restoration of overall hand function compared to surgical treatment.

Biophysical Stimulation in Delayed Fracture Healing of Hand Phalanx: A Radiographic Evaluation.
Biomedicines
Phalangeal fractures are common events among the upper limbs accounting for 10% of all human body fractures. Fracture complete healing process may persevere several months or years. Most phalangeal fractures present favorable union within 3 to 6 weeks. In the literature, biophysical stimulation has yielded favorable outcomes in the treatment of hand fractures. A survey involving hospitals in the US reported the use of biophysical stimulation (72%) in relation to nonhealing fractures at three months after trauma. A noninvasive procedure such as biophysical stimulation may be preferential prior to consideration of invasive procedures. In this retrospective study, we analyzed 80 phalangeal fractures, 43 of which did not show any radiographic sign of healing 30 days after surgery; on radiograms, we calculated radiographic data and the total active motion (TAM) for clinical comparison. All radiographic images were evaluated using Adobe Photoshop CS3 (version 10.0, Adobe Systems Inc., San Jose, CA, USA). We calculated the index of relative bone healing each month after surgery starting from 30 days, which was considered as T1, and followed up for a total of 6 months after stimulation (T6) with better results in stimulated groups. We concluded that prompt administration of biophysical stimulation supports fracture healing and yields an important improvement in the union rate compared with nontreatment. Above all, our patients experienced less injury-related distress between the fracture and repair period, which consequently reduced immobilization time, envisaging an early rehabilitation interval, with a better patient hand outcome.

Intramedullary Screw Fixation Comprehensive Technique Guide for Metacarpal and Phalanx Fractures: Pearls and Pitfalls.
Plastic and reconstructive surgery. Global open
BACKGROUND:Phalangeal and metacarpal fractures are the second and third most common upper extremity fractures after distal radius fractures with varying methods of fixation techniques. Intramedullary screw fixation is an increasingly preferred method of fixation. Benefits include early range of motion, faster recovery, limited dissection, and reduced complications. Improper technique, which is readily avoidable, can lead to suboptimal results. METHODS:A review of recent literature on current techniques aims to summarize the biomechanics of intramedullary screw fixation and outline appropriate technique of placing headless compression screws for metacarpal and phalangeal fractures. RESULTS:We discuss through images and videos the indications, preoperative workup, and technical pearls and pitfalls to encourage surgeons to add this technique to their armamentarium and improve outcomes. CONCLUSIONS:intrameduallry screw fixation is a powerful option for metacarpal and phalanx fixation that allows rigid stability, enabling early return of function with excellent rates of union and total active motion. With knowledge of technical pearls presented in this article, common mistakes can be avoided to improve efficiency of screw placement and optimize patient outcomes.

Schiffner Erik,Latz David,Grassmann Jan P,Schek Alberto,Scholz Armin,Windolf Joachim,Jungbluth Pascal,Schneppendahl Johannes
The Journal of sports medicine and physical fitness
BACKGROUND:Aim of this retrospective cohort study was to identify fracture epidemiology and off times after different types of fractures in German male elite soccer players from the first division Bundesliga based on information from the public media. METHODS:Exposure and fracture data over 7.5 consecutive seasons (2009/10 until the first half of 2016/17) were collected from two media-based register (transfermarkt.de® and kicker.de®). RESULTS:Overall, 357 fractures from 290 different players were recorded with an incidence of 0.19/1000 hours of exposure (95% CI: 0.14-0.24). Most fractures in German elite soccer players involved the lower extremities (35.3%), the head/face (30.3%) and the upper extremities (24.9%). The median off time after a fracture in German elite male professional soccer in 7.5 Season was 51.1 days (range 0-144). The number of fractures per 100 players per season decreased between 2009 and 2016. There was no significant difference in overall fracture incidence when comparing players at different position (P=0.11). Goalkeepers have a significantly (P<0.02) higher likelihood of suffering hand and finger fractures and they are significantly (P<0.03) less prone of suffering foot fractures, cranial and maxillofacial fractures (P<0.04). compared to outfield players. CONCLUSIONS:This study can confirm that male professional soccer teams experience 1-2 fractures per season in German elite soccer. The incidence of fractures in elite German soccer players decreased between 2009 and 2016. The most fractures occur in the lower extremities and there is no difference in overall fracture risk for players at different playing positions. The information from our study might be of a great importance to medical practitioners, soccer coaches and soccer manager.

Yamamoto Y,Ichihara S,Suzuki M,Hara A,Hidalgo Díaz J J,Maruyama Y,Kaneko K
Hand surgery & rehabilitation
External fixators are an effective treatment option for comminuted or unstable phalangeal fractures. We developed a new linked-wire type of external fixator (the Ichi-Fixator) for finger phalangeal fractures, which enables fine adjustment of the fixation under fluoroscopy guidance either in a static way or with distraction through small screws inside the fixator. This technique was designed to improve on the stability and rigidity of conventional percutaneous Kirchner wire fixation. We assessed the effectiveness of the fixator through 12 cases of open or percutaneous fixation in comminuted or unstable phalangeal fractures. All patients were examined for postoperative complications, functional recovery, pain on visual analog scale (VAS), and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score at the final follow-up visit. Patients could perform all routine activities with normal grip strength and a full range of hand motion without pain after treatment. This treatment, which reduces the postoperative discomfort and may allow an immediate return to work, will clearly boost patient satisfaction. Linked-wire type external fixation enhances the security of fixation, facilitates postoperative mobilization, and may allow an immediate return to work.

Phalangeal and Metacarpal Fractures in Children: A 10-Year Comparison of Factors Affecting Functional Outcomes in 313 Patients.
Journal of hand and microsurgery
It is widely believed that fractures in children have excellent clinical outcomes due to their capacity to remodel. There are, however, certain fractures that require careful management to avoid long-lasting functional impairment. Functional outcomes following hand fractures in children are poorly studied. We performed a retrospective cohort study of consecutive children and adolescents who had operative treatment for metacarpal and phalangeal fractures (2008-2018). Tuft fractures and replantations were excluded. Functional outcomes were measured by total active motion (TAM) scoring, where a "good" outcome = TAM > 75%. Fractures were categorized by location, classification, and by the fixation they required. Three hundred thirteen children were included. For proximal phalangeal fractures, those treated by manipulation under anesthesia, had a higher proportion of "good" functional outcomes than Kirschner-wire or open reduction internal fixation at discharge from hand therapy ( = 0.043). Middle phalanx fractures had excellent functional outcomes, with no difference between fixation methods ( = 0.81). For metacarpals, there was no statistically significant difference in functional outcomes across all managements ( = 0.134). Fractures in the thumb had poorer postoperative function at mean 7.26 weeks than those in the long fingers ( < 0.0001), and the data suggested a trend toward worse outcomes in the distal phalanx, pediatric Bennett fractures, Seymour fractures, and oblique fractures. Fractures in the thumb and phalangeal fractures that require percutaneous or open fixation may need closer early postoperative monitoring in children to optimize their potential for good function.

Design Parameters of Hand Surgery Screws: Measurement Discrepancies and Clinical Implications.
Journal of hand surgery global online
Purpose:The use of self-tapping cortical screws is indicated in patients with metacarpal and phalangeal fractures requiring formal stabilization. The aim of this study was to systematically compare and evaluate the design parameters of 4 commercially available self-tapping screw systems. Methods:We measured various design parameters of self-tapping cortical screws of different lengths from several manufactures using scanning electron microscopy. Screws were obtained in 8, 12, 16, and 20 mm lengths. The measured parameters included screw length, head height, pitch, outer diameter, inner diameter, terminal thread diameter, terminal thread-to-tip distance, thread-to-tip distance of 1 full revolution, and crest width. Data were assessed statistically using 1- and 2-way analysis of variance (ANOVA) tests, and the significance level was set at a value < .05. Results:There was variability in advertised screw lengths compared with measured screw lengths with 2 manufacturers. There was a statistically significant difference between the thread-to-tip distance and head height between screws while controlling for diameter. Conclusions:Screw sizes and dimensions are critical in order to avoid complications such as prominent hardware and postoperative stiffness. Knowledge of the design parameters presented for each of the different manufacturers may prove useful to hand surgeons when selecting screws for fixation of metacarpal and phalangeal fractures. Clinical relevance:Specific design characteristics of commonly used screws in hand surgery vary slightly by manufacturer and may have clinically relevant implications in fixation of metacarpal and phalangeal fractures.

Risk Factors for Nonunion After Distal Phalangeal Fractures of the Hand.
The Journal of hand surgery
PURPOSE:This study aimed to evaluate the risk factors for distal phalanx fracture nonunion. METHODS:We retrospectively reviewed all adult patients treated for distal phalanx fractures at our institution between January 2015 and December 2019 with a minimum one-year follow-up period for potential risk factors. The absence of consolidation signs on follow-up radiographs at least 12 months after trauma was defined as nonunion. RESULTS:This study included 124 patients with 143 fractures available for follow-up. Nonunion was diagnosed in 19 patients, 18 of whom initially presented with an open fracture. On the day of the injury, 17 patients with open fractures presented to the hospital. In 16 nonunion cases, the traumatic mechanism was a crush injury. All nonunions occurred in tuft fractures, and none required revision surgery at the follow-up visit. CONCLUSIONS:Our findings suggest that tuft involvement in open fractures is the main risk factor for nonunion of distal phalangeal fractures. However, after a minimum of 1 year of follow-up, none of the tuft nonunions required revision surgery. TYPE OF STUDY/LEVEL OF EVIDENCE:Therapeutic IV.

Investigating Patient-Level Radiation Exposure in Hand and Wrist Fracture Surgery.
Annals of plastic surgery
BACKGROUND:Although occupational exposure to radiation has been previously studied in the hand surgery literature, there is a paucity of studies looking at radiation exposure to the patient during fluoroscopy-guided hand surgery. We aimed to describe the level of radiation experienced by patients undergoing common hand and wrist fracture fixation and to identify risk factors for increased radiation exposure. METHODS:We performed a retrospective review of patients at a single institution who underwent fracture fixation of the hand, wrist, or forearm requiring mini c-arm fluoroscopic guidance from 2016 to 2020. Data points collected included patient demographics, procedural details, and indicators of radiation exposure including dose-area product (DAP), total intraoperative images, and total fluoroscopy time. Effective dose (ED) was calculated using DAP, field size, and a previously established conversion factor. RESULTS:The final sample included 361 patients with an average age of 46 years. Procedures included fixation of forearm fractures (3.3%), distal radius fractures (35.7%), metacarpal fractures (30.8%), and phalangeal fractures (30.2%). The median number of intraoperative images acquired was 36, median total fluoroscopy time was 43 seconds, median DAP was 4.8 cGycm2, and median ED was 0.13 μSv. Distal (metacarpal and phalangeal) fractures required more intraoperative images and longer total fluoroscopy time (49 images, 61 seconds) compared with proximal (forearm and distal radius) fractures (39 images, 47 seconds) (images, P = 0.004; exposure time, P = 0.004). However, distal fractures had a lower average ED compared with proximal fractures (0.15 vs 0.19 μSv, P = 0.020). When compared with open procedures, percutaneous procedures had higher DAPs (8.8 vs 4.9 cGycm2, P < 0.001), higher ED (0.22 vs 0.15 μSv, P < 0.001), more intraoperative images (65 vs 36 images, P < 0.001), and longer total fluoroscopy time (81.9 vs 44.4 seconds, P < 0.001). CONCLUSIONS:Patient-level radiation exposure during fluoroscopy-guided hand and wrist procedures is low relative to other common imaging modalities, such as dental radiographs, chest x-rays, and computed tomography scans, and is comparable with less than a few hours of natural background radiation exposure, highlighting the overall safety of this important technology. Further study should be performed to establish reference ranges, which could lead to improved patient counseling and evidence-based guidelines on patient shielding.

Finger fractures: Epidemiology and treatment based on 21341 fractures from the Swedish Fracture register.
PloS one
BACKGROUND:There is a lack of detailed epidemiological studies of finger fractures, the most common fracture of the upper extremity. METHODS:Based on data of 21 341 finger fractures in the Swedish Fracture register, a national quality registry that collects data on all fractures, this study describes anatomical distribution, cause, treatment, age distribution, and result in terms of patient related outcome measures (PROMs). RESULTS:The most common finger fracture was of the base of the 5th finger, followed by the distal phalanx in the 4th finger. Open fractures were most common in the distal phalanges, especially in the 3rd finger. Intraarticular fractures were most frequent in the middle phalanges. Fall accidents was the most common cause of a fracture. The mean age at injury was 40 years (38 for men, 43 for women). 86% of finger fractures in adults were treated non-operatively. Men were more frequently operated than women. Finger fractures did not affect hand function or quality of life and there were no relevant differences in PROMs between fracture type, treatment, or sex. CONCLUSION:This study presents detailed information about the various types of finger fractures which can be used as point of reference in clinical work and for future studies.

Return to Sport After Metacarpal and Phalangeal Fractures: A Systematic Review and Evidence Appraisal.
Orthopaedic journal of sports medicine
BACKGROUND:Fractures of the metacarpals and phalanges account for more than half of all upper extremity fractures sustained by competitive athletes. PURPOSE:To determine which management strategy is best for expediting return to preinjury levels of competition in adult athletes with metacarpal and/or phalangeal fractures. STUDY DESIGN:Systematic review; Level of evidence, 4. METHODS:A methodology compliant with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was used. A custom search strategy was designed and applied to MEDLINE and In-Process, Embase, EMCARE, and CINAHL. RESULTS:Overall, 3135 records were identified, of which 8 met full inclusion criteria. All patients returned to preinjury levels of competition, at a mean of 30.6 days for phalangeal fractures and 21.9 days for metacarpal fractures. Meta-analysis demonstrated delayed return-to-sport time for operatively managed metacarpal fractures as compared with nonoperatively managed ones (28.5 vs 22.0 days). All studies were of fair or poor quality, and none were randomized. CONCLUSION:Optimal management strategies for athletes with metacarpal and phalangeal fractures remain equivocal. Injury, treatment, and sport-specific factors may confound results and preclude accurate estimation of optimal treatment strategies at present.

WALANT Technique in Percutaneous Scaphoid Osteosynthesis.
Revista brasileira de ortopedia
Scaphoid fractures account for 50 to 70% of all carpal bone fractures. Percutaneous scaphoid osteosynthesis can use the dorsal or volar approach, both with good results, and is most commonly performed under general anesthesia or regional nerve block. The wide-awake local anesthesia no tourniquet (WALANT) technique is already considered a safe and cost-effective technique in hand surgery around the world. Local anesthesia with epinephrine causes vasoconstriction, which obviates the need for tourniquet and, consequently, the need to use patient sedation. Thus, the possibility of testing fixation stability under physiological forces is another great advantage of using local anesthesia. In the technique described in the present paper, active wrist and hand motion can be tested immediately after scaphoid fixation. Wide-awake local anesthesia no tourniquet has been increasingly used in soft-tissue hand surgery and in the fixation of metacarpal and phalangeal fractures. However, to date, there is no published literature addressing the use of this technique in percutaneous scaphoid osteosynthesis. The purpose of the present technical note is to describe the use of WALANT for both the dorsal and volar approaches in percutaneous scaphoid osteosynthesis.

Background:Despite the relatively high incidence of phalangeal fractures, there is an imperfect understanding of the epidemiology and anatomical distribution of these fractures. This study describes the patient characteristics, anatomic distribution, and detailed fracture patterns of phalangeal fractures among a large adult cohort in the United States. Methods:A retrospective study was performed among patients with phalangeal fractures in the United States between January 2010 and January 2015. Included patients were 18 years old or older and had a diagnosis of a phalangeal fracture. A total of 2140 phalangeal fractures in 1747 patients were included, and a manual chart review was performed to collect epidemiological and radiographic information. Fractures were classified based on location and fracture pattern. Results:The median age at the time of injury was 45 years (interquartile range, 30-57), and 65% of patients were men. The small finger had the highest incidence of fractures (26%) followed by the ring finger (24%). Distal and proximal phalanges demonstrated the highest incidence of fractures at 39% each. The dominant hand was affected in 44% of cases. Eighteen percent of fractures were due to a work-related trauma mechanism, and the most common mechanism of injury was blunt trauma (46%). Conclusion:This study provides a detailed overview of the anatomic distribution and fracture patterns of phalangeal fractures in an adult US population and, thus, may aid hand surgeons treating these injuries.

Wide-Awake Surgical Management of Hand Fractures: Technical Pearls and Advanced Rehabilitation.

Plastic and reconstructive surgery
Most unstable metacarpal and phalangeal fractures for which operative treatment is indicated can be reduced and stabilized with either open or closed techniques using local anesthetic with epinephrine instead of intravenous sedation or general anesthesia. With the patient wide-awake during surgery, the hand can be taken through active range of motion to assess fracture stability. In this article, the authors review the rationale and technique for wide-awake, local anesthesia, no tourniquet surgery in the treatment of phalangeal and metacarpal fractures and impart pearls to optimize the patient experience and illustrate common fixation techniques using percutaneous Kirschner wires. The intraoperative assessment of fracture stability permits an accelerated, protected-range-of-motion protocol that minimizes postoperative stiffness and facilitates expedient recovery.

Reoperation After Operative Treatment of Open Finger Fractures.
Hand (New York, N.Y.)
BACKGROUND:Our primary aim was to develop a prediction model for return to the operating room (OR) after open finger fractures by studying the reoperation rate of open finger fractures based on patient demographics, injury mechanism, injury severity, and type of initial surgical fixation. The secondary aim was to study the predictors for secondary surgery due to nonunion, postoperative infection, and secondary amputation. METHODS:In the retrospective chart review, 1321 open finger fractures of 907 patients were included. Demographic-, injury-, and treatment-related factors were gathered from medical records. RESULTS:We found that open fractures involving the thumb had lower odds of undergoing secondary surgery. Crush injury, proximal phalangeal fracture, arterial injury, other injured fingers, and other injuries to the ipsilateral hand were associated with higher odds of undergoing secondary surgery. However, the associated factors we identified were not powerful enough to create a predictive model. Other injury to the ipsilateral hand, vein repair, and external fixator as initial treatment were associated with postoperative nonunion. Crush injury and proximal phalangeal fracture were associated with postoperative infection. No factors were associated with secondary amputation. CONCLUSIONS:A quarter of open finger fractures will likely need more than one surgical procedure, especially in more severely injured fingers, due to crush or with vascular impairment. Furthermore, fractures involving the thumb have less reoperation, while fractures involving the proximal phalanx have poorest outcomes.

Fractures of the phalanges.
The Journal of hand surgery, European volume
Fractures of the phalanges encompass a wide range of injury patterns with variable articular and soft tissue involvement. The goals of treatment whether conservative or surgical are the restoration of function while limiting the risk of complications. An armamentarium of fixation options allows the surgeon to appropriately treat these fractures with the intention of initiating early postoperative mobilization. Previous publications report variable rates of complications following internal fixation of phalangeal fractures which represents an unsolved problem. It is incumbent on the surgeon to utilize meticulous surgical technique, achieve anatomic reduction with stable fixation and initiate early postoperative mobilization where indicated. In the following text, we review the management of most types of phalangeal fractures, except fracture-dislocations of the proximal interphalangeal joint. These injuries comprise a wide spectrum of presentation; thus, an understanding of anatomical and mechanical principles is integral to achieving a successful outcome.
