Abstract
Subacute or late-presenting unstable osseous mallet finger might be hard to reduce and, therefore, remain subluxed when using the traditional Ishiguro technique. In such cases, we suggest it is best to prioritize correction of joint subluxation over step-by-step adherence to the traditional Ishiguro technique. Specifically, we contend that carrying out the procedure in reverse order typically results in an easier and more stable reduction of both joint and fracture.

Abstract
INTRODUCTION Tendinous and bony mallets are very different injuries that present with extensor lag at the distal interphalangeal joint. This study aimed to evaluate the differences in outcomes between acute bony and tendinous mallet fingers treated conservatively with splints. MATERIALS AND METHODS We retrospectively collected data on patients with acute tendinous or bony mallets who received conservative treatment in our occupational therapy clinic. The patients were examined at an outpatient clinic, where data on pain, extension lag, and loss of flexion were recorded. Outcomes were classified according to the criteria described by Crawford. RESULTS Data were collected from 133 patients (43 with bony and 90 with tendinous mallets). We found that bony mallet patients were predominantly younger (mean, 36 vs. 46 years), and more likely to be female (60% vs. 34%), than tendinous mallet patients. We also found that tendinous mallet injuries predominantly affected the middle and ring fingers, while bony mallet injuries predominantly affected the ring and little fingers. The initial extensor lag was worse in tendinous than in bony mallets (median, 28° vs. 15°). In addition, patients with bony mallets had significantly better outcomes with regard to the extension lag (median 0° vs. 5° p = 0.003) and the Crawford Criteria Assessment (p = 0.004), compared with those with tendinous mallets. DISCUSSION Mallet injuries, both tendinous and bony, are common. They are often studied together and typically treated in the same manner using extension splints. However, evidence clearly shows that these are different injuries which present in the same manner. This study reinforces these findings and suggests that the outcome of conservative treatment is better for bony than for tendinous mallet fingers.

Abstract
Mallet injuries, either tendinous or bony, are common. They are often studied together and typically treated in the same way with extension splintage for 6 to 8 weeks. Yet the evidence clearly shows there are different injuries that present in the same way. Tendinous mallet injuries present in older patients usually following a low energy injury; they are often painless. The commonly injured fingers are the middle and ring. The injuries are almost always single digit without concomitant injuries. There is an extensor lag of a mean of 310 (range 3°-590) in the patients treated in my unit. In contrast, bony mallet injuries occur at a younger age (mean 40 years) and are always due to high energy injuries. The injuries are always painful. The commonly injured fingers are the ring and little fingers. There are multiple injuries in 3% (range 2%-5%) and in 4% to 8% of cases, there are concomitant (nondigital) injuries according to data in my unit. Radiologically there is an appreciably smaller extensor lag; mean 130 (range 0°-400). In particular, bony mallet injuries are extension compression, not avulsion, fractures which should not logically be treated with an extension splint which will reproduce the direction of injury.

Comparison of extension block pinning technique versus pin orthosis-extension block pinning technique for acute mallet fractures: a prospective randomized clinical trial. Arch Orthop Trauma Surg 2022; 142:1301-1308. [PMID: 35041082 DOI: 10.1007/s00402-022-04348-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Accepted: 01/04/2022] [Indexed: 11/28/2022]
Abstract
INTRODUCTION The extension block pinning technique (EBPT) is a popular surgical treatment for mallet fractures; however, it has several drawbacks. The purpose of this randomized clinical trial was to compare EBPT to the pin orthosis-extension block pinning method (PO-EBPT) in the treatment of mallet fractures involving more than one-third of the joint surface but without primary joint dislocation. MATERIALS AND METHODS Sixty-five patients with mallet fractures were randomized into two groups between June 2017 and January 2020: Group I (33 patients) was treated with EBPT and group II (32 patients) was treated with PO-EBPT. Five patients were lost to follow up due to lack of follow-up and death. There were no significant differences in the clinical and demographic characteristics of both groups. Patients were evaluated according to fracture union, extension lag, distal interphalangeal (DIP) joint range of motion, Crawford's criteria, and complication rates. The patients were followed-up post-operatively at 2 weeks, 6 weeks, 3 months, 6 months, 1 year, and annually thereafter. RESULTS A total of 60 patients were randomized into two groups: one (30 patients) was treated with EBPT and the second (30 patients) with PO-EBPT. There were no significant differences between the two groups in terms of fracture union and active DIP joint flexion (P = 0.743 and P = 0.059, respectively). The mean extension lag of the DIP joint in the EBPT group was significantly greater than the PO-EBPT group (10° ± 9.47° vs. 4.17° ± 7.2°, P = 0.009). According to the Crawford criteria, the PO-EBPT group showed significantly better outcomes (P = 0.005). The complication rates were similar between groups (P = 0.45). CONCLUSION In comparison to the EBPT technique, the group of patients operated with PO-EBPT had superior clinical outcomes and less loss of extension at the DIP joint according to the Crawford's criteria.

Abstract
OBJECTIVES The aim of this study was to evaluate the functional results of delayed open reduction and Kirschner wire (K-wire) fixation procedures in patients with delayed presentation of bony mallet finger. PATIENTS AND METHODS Between February 2009 and November 2019, a total of 19 patients (15 males, 4 females; median age: 24.8 years; range, 14 to 47 years) who were diagnosed with a delayed bony mallet finger and treated with dorsal block pin, direct pinning, or the umbrella handle technique were retrospectively analyzed. The Crawford criteria were used to evaluate the outcomes. The degrees of range of motion (ROM) were measured by a goniometer. RESULTS The median time from injury to surgery was 41 (range, 28 to 90) days. The median DIP joint extension limitation was 7.63 (range, 0 to 40) degrees and the median ROM of the DIP joint was 66.3 (range, 20 to 90) degrees. There was no statistically significant difference in the postoperative ROM, compared to the uninjured side (p>0.05). The Crawford score was excellent in 11, good in four, fair in three, and poor in one patient. Bone union was achieved in all patients. CONCLUSION Delayed open reduction and K-wire fixation of chronic bony mallet finger injuries yield successful functional outcomes with low complication rates. Extension lag can be eliminated in most patients by making the joint surface anatomical. The most optimal method should be selected depending on the size of the fracture fragment.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Describe treatment options for phalangeal fractures. 2. Choose an appropriate fracture management plan that optimizes patient goals and range of motion. 3. Describe closed and open reduction techniques of commonly encountered phalangeal fracture patterns. SUMMARY Phalangeal fractures are the second most common upper extremity fracture. Although many can be treated with splinting, operative intervention may be required for unstable fracture patterns and those involving the articular surface. Failure to appropriately treat these fractures can result in finger stiffness, loss in range of motion, and functional deficits. The type of fixation method can range from percutaneous pinning to open reduction and internal fixation. This article presents a series of cases to illustrate the appropriate management of phalangeal fractures using an evidence-based approach.

HAND SURGERY & REHABILITATION 2021; 41:131-136. [PMID: 33848651 DOI: 10.1016/j.hansur.2021.03.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 01/21/2021] [Accepted: 03/05/2021] [Indexed: 11/29/2022]
Abstract
The aim of this study was to compare the closed reduction interfragmentary pinning method (IPM) with the extension block technique (EBT) for bony mallet finger. Patients who underwent mallet finger operations were screened retrospectively for the following inclusion criteria: Doyle type 4c, age between 18 and 75 years, less than 4 weeks to surgery, and more than 1 year of follow-up time. Group I underwent a closed reduction IPM, and group II underwent the EBT. Lateral radiographs taken during the preoperative and final examination were used to evaluate the size and amount of displacement from the distal interphalangeal (DIP) joint and the dorsal fragment as well as the articular surface. Operation times were compiled from patient records. During the final examination, pain and DIP joint range of motion (ROM) were assessed and complications were recorded. The Crawford criteria were used for functional results. Fifteen patients in group I (8 men, 7 women) and 17 patients in group II (10 men, 7 women) were evaluated. Age, gender, time to surgery and follow-up time showed no statistically significant differences between the two groups. The differences in fragment size, preoperative and postoperative joint displacement, amount of dorsal displacement and DIP joint ROM were not statistically significant between the two groups. However, the operation time was significantly shorter time in group I than in group II (p=0.000). The average time to fracture union was significantly longer in group I (7.3 weeks) than in group II (6 weeks) (p=0.013). The EBT has faster time to union and is a safer method with lesser risk of arthritis and fragmentation. The IPM can be an alternative with shorter operation time, less pin bed infection and nail bed damage, especially in Doyle type 4c cases with large fragments.

Abstract
Mallet fractures are avulsion fractures of the extensor tendon from the distal phalanx base and often occur due to sudden flexion or axial loading. In this study, we aimed to compare the clinical and radiological results of patients treated with single and double dorsal wires from the dorsal in the extension block method.Patients to whom a single wire from dorsal was applied were assigned to Group 1 (n: 22), and those to whom double wires were applied were assigned to Group 2 (n: 23). Surgical treatment was decided for patients with more than 1/3 of the fracture fragment containing the joint surface and volar subluxation. The range of motion of the distal interphalangeal (DIP) joint was measured with a goniometer. The displacement of the fragment was measured before and after surgery on lateral radiographs. The presence of bridging callus formation on anterior-posterior and lateral radiographs was evaluated for a union.There were 30 male (66.7%) and 15 (33.3%) female patients. The mean age of the patients was 32 years. Radiographic union was obtained in all patients. Pseudoarthrosis was not observed in any patient. The Crawford score was excellent in 13 (28.9%) cases, the score was good in 18 (40%) cases, the scores were moderate in 13 (28.9%) cases, and the score was poor in 1 case (2.2%). There were no complications in 35 (77.8%) cases, dorsal bump complications occurred in 9 cases (20%), and osteoarthritis and dorsal bump complications occurred in 1 (2.2%) case. We did not observe nail deformity, skin necrosis, infection, or fingertip sensitivity. We found similar functional and clinical results between the groups.We recommend using single dorsal wire, as using double dorsal wires requires extra operation time, effort, and fluoroscopy.

Abstract
Japan has faced the most challenging times in the past. Through precise diligence by stalwarts and doyens of initial hand surgeons, it led an incredible path for the most significant moments of hand surgery. This article describes the early phase of development of Japanese Society for Surgery of the hand, substantial and innovative contributions from surgeons. A noteworthy and significant achievement in the hand surgery is microsurgery and its utilities for all hand-related diseases. The first replantation of the thumb, toe transfers and wrap-around flaps are the effective surgical techniques developed and imparted to the fellow hand surgeons worldwide. We had a particular interest in congenital hand surgery and developed a modification of congenital hand classifications and introduced many surgical techniques. Besides, we grew ourselves refining more in hand and microsurgery, innovating flexor tendon repair, peripheral nerve surgeries, wrist arthroscopy, joint replacements, external fixators, and implant arthroplasty for rheumatoid hand. We share our health care information, insurance working model and hand surgery training schedule in Japan.

Abstract
Extension-block pinning is a popular surgical treatment method for mallet fractures but is associated with several pitfalls. Transfixation Kirschner wires used in the extension-block pinning technique may cause iatrogenic nail bed injury, bone fragment rotation, chondral damage, or osteoarthritis. The objective of this study was to determine the result of the delta wiring technique in mallet fractures with fracture fragment involving more than one-third of the distal phalanx articular surface. The authors are reporting 5 cases of mallet fractures treated with delta wiring technique with good functional and radiologic outcomes. Radiologic outcomes were evaluated on the basis of postoperative and follow-up x-rays and functional outcomes were evaluated using Crawford's criteria. Five patients (4 males, 1 female) with a mean age of 26.8 years (range, 20 to 33 y) were included. The mean time between the injury and surgery was 5 days (range, 3 to 7 d), and the mean follow-up period was 8.6 months (range, 8 to 10 mo). Radiographic bone union was achieved in all patients within an average of 6.4 weeks (range, 6 to 7 wk). At the final follow-up, the distal interphalangeal joint had an average degree of flexion of 73 degrees (range, 70 to 75 degrees) and an average extension deficit of 5.40 (range, 0 to 8 degrees). According to Crawford's criteria, 1 patient had excellent results and 4 patients had good results. No patient reported pain at the final follow-up with a visual analog scale score mean of 0.6 (range, 0 to 2). Satisfactory clinical and radiologic outcomes were obtained with the delta wiring technique. Future prospective and randomized studies are justified to confirm the efficacy of this technique.

The objective of this study was to determine the result of the delta wiring technique in a case of mallet finger with fracture fragment involving more than one-third of the distal phalanx articular surface. This is the first reported case of mallet fracture treated with delta wiring in literature. Case Report A 30-year-old male patient admitted in our institute with complaints of severe pain in the right index finger with inability to extend the distal interphalangeal joint (DIP) for 5 days. There was a history of fall from the bike before this complaint. Radiographs revealed a bony mallet fracture involving more than one-third of the articular surface of distal phalanx. The patient was taken up for delta wiring fixation of the fracture. Radiographic bony union was seen at 7 weeks. At the final follow-up at 1 year, DIP had 75° of flexion and had extension deficit of 5°. According to Crawford's criteria, the patient had good results with a VAS score of 1 with no pain. Conclusion Delta wiring technique is a new and safe treatment modality for bony mallet fracture with fracture fragment involving more than one-third of the distal phalanx articular surface as satisfactory clinical and radiological outcomes obtained in our case.

Abstract
Dorsal extension block pinning is a commonly performed surgical technique for acute bony mallet fingers. However, the treatment of chronic bony mallet finger remains controversial. We investigated the use of dorsal extension block pinning with percutaneous curettage for chronic bony mallet fingers. Seven patients with chronic bony mallet fingers were treated by dorsal extension block pinning with percutaneous curettage. The average age was 17 (range, 12-23) years, and the average time from injury to surgery was 20 (range, 7-49) weeks. Bone union was achieved in all patients. None of the patients experienced pain after bone union. The average loss of distal interphalangeal joint extension was 6 (range, 5-20) degrees, and the average flexion was 59 (range, 40-80) degrees. The Crawford functional score was excellent in three patients, good in two, and fair in two. Dorsal extension block pinning with percutaneous curettage could be a useful treatment for chronic bony mallet fingers.

Abstract
Background Mallet fracture can easily occur during sports activities or in daily life; however, the principles and methods of treatment for such fractures remain debated. Among the surgical treatments, various methods of closed reduction have been proposed. We treated patients with the extension block method (EBM) and the direct pinning method (DPM), and then compared the results. We assessed differences in range of motion and measurements of finger movement after surgery. Methods A total of 41 patients who underwent surgery from August 2013 to September 2015 were evaluated retrospectively. Among them, 21 patients were treated with the EBM and 20 patients were treated with the DPM. We then compared extensor lag, range of motion, and outcomes according to Crawford’s criteria between before surgery and at 6 to 8 months postoperatively. Results The postoperative extensor lag improvement was 4.28° and 10.73°, and the postoperative arc of motion was 55.76° and 61.17° in the EBM and DPM groups, respectively. The Crawford assessment showed no statistically significant difference between the groups, although the score in the DPM group was higher than that in the EBM group (3.5 vs. 3.1). Conclusions As closed reduction methods for the treatment of mallet fracture, both the EBM and DPM showed good results. However, the DPM proved to be superior to the EBM in that it produced greater improvements in extensor lag and range of motion.

Abstract
BACKGROUND Bony avulsion fractures of the distal phalanges can result in mallet finger deformity if not treated appropriately. Therefore, only minimally displaced fractures can be treated conservatively with a good outcome, as dislocation occurs very often. Several surgical treatment options have been developed during the past decades. Data concerning the recently developed hook plate are promising. So far, no data concerning the subjective satisfaction with this method have been published. Therefore, we have analyzed the outcome after hook plate implantation using a self-assessment score, which focuses also on subjective parameters and satisfaction. METHODS Standardized questionnaires (self-assessment scores and SF-36 questionnaire) were sent to each patient treated with a hook plate due to fracture of the distal phalanx, type Doyle IVb and IVc. Clinical data were evaluated according to the medical record. Scores given per question range from 0 to 10, 10 is the worst and 0 the best outcome. RESULTS From 69 patients treated, 38 (58%) were enrolled. The whole collective (n = 38) reached a score of 39.7 ± 28.7 points, while men had slightly better results. Men (n = 24) achieved 37.3 ± 27.9 points, women (n = 14) 43.9 ± 30.7 points. Women had significantly better results when analyzed later than 12 months after surgery (52.1 ± 27.9 vs. 29.1 ± 32.8), whereas no changes could be detected in the male group (37.1 ± 29.9 vs. 37.4 ± 27.6). Overall, men were slightly more satisfied than women. Most satisfaction was found regarding pain and fine motor skills (0-0.46 points). Esthetic aspect and nail deformities (3.65 points average) led to the highest dissatisfaction. No differences in the SF 36 score could be detected. CONCLUSIONS The hook plate is not only a convenient method but it also results in high patient satisfaction. Nail deformities are challenging; however, with increasing experience of the surgeon they decrease. SF 36 score is not an appropriate testing tool for this problem.

Abstract
INTRODUCTION Extension-block pinning represents a simple and reliable surgical technique. Although this procedure is commonly performed successfully, some patients develop postoperative extension loss. To date, the relationship between extension-block Kirschner wire (K-wire) insertion angle and postoperative extension loss in mallet finger fracture remains unclear. HYPOTHESIS We aimed to clarify this relationship and further evaluate how various operative and non-operative factors affect postoperative extension loss after extension-block pinning for mallet finger fracture. MATERIALS AND METHOD A retrospective study was conducted to investigate a relationship between extension block K-wire insertion angle and postoperative extension loss. The inclusion criteria were: (1) a dorsal intra-articular fracture fragment involving 30% of the base of the distal phalanx with or without volar subluxation of the distal phalanx; and (2) <3 weeks delay from the injury without treatment. Extension-block K-wire insertion angle and fixation angle of the distal interphalangeal (DIP) joint were assessed using lateral radiograph at immediate postoperative time. Postoperative extension loss was assessed by using lateral radiograph at latest follow-up. Extension-block K-wire insertion angle was defined as the acute angle between extension block K-wire and longitudinal axis of middle phalangeal head. DIP joint fixation angle was defined as the acute angle between the distal phalanx and middle phalanx longitudinal axes. RESULTS Seventy-five patients were included. The correlation analysis revealed that extension-block K-wire insertion angle had a negative correlation with postoperative extension loss, whereas fracture size and time to operation had a positive correlation (correlation coefficient for extension block K-wire angle: -0.66, facture size: +0.67, time to operation: +0.60). When stratifying patients in terms of negative and positive fixation angle of the DIP joint, the independent t-test showed that mean postoperative extension loss is -3.67° and +4.54° (DIP joint fixation angles of <0° and ≥0°, respectively, P=0.024). When stratifying patients in terms of extension-block K-wire insertion angle (30°, 30°-40°, >40°), ANOVA showed significantly less postoperative extension loss for higher insertion angles (>40°) than for medium insertion angles (30°-40°). Mean postoperative extension loss difference between higher insertion angle (>40°) and medium insertion angle (30°-40°) was 11° (P=0.002). DISCUSSION Using an insertion angle of the extension-block K-wire of 40°-45° and a slightly hyperextended position of the DIP joint may help reducing postoperative extension loss. LEVEL OF EVIDENCE Therapeutic level III.

Abstract
BACKGROUND Many surgeons advocate for surgical intervention of adult mallet fractures that involve either subluxation of the distal interphalangeal (DIP) joint or those that involve more than one-third of the articular surface. However, the efficacy of operative treatment and complication rates are unclear regarding the adolescent population. QUESTIONS/PURPOSES The goal of this study is to evaluate the clinical outcomes following operative fixation of bony mallet fractures in the adolescent population. METHODS Seventeen patients with bony mallet fractures treated surgically were retrospectively reviewed. Twelve patients were treated by closed reduction with extension block pinning. The other patients underwent an open reduction and pin fixation. The average age was 15.2 years (13-18). Most injuries were sport related. The average time from injury to presentation was 17 days and from injury to surgery was 24.5 days. Nine patients had subluxation at the DIP joint and all involved at least one-third of the articular surface. RESULTS The average time from surgery to pin removal was 28 days (19-46). All distal phalanx physis were closed or nearly closed. One patient reported pain at the final follow-up. Two patients (11.8%) had major complications. One had an extension contracture postoperatively, did not attend therapy, and re-fractured 5 months later requiring reoperation. The second was treated delayed (32 days) and lost fixation, requiring revision surgery and antibiotics for a superficial infection. Two patients with delayed treatment (32 and 44 days) had an extensor lag (11.8%). CONCLUSIONS Operative treatment of mallet fractures with subluxation or involving more than one-third of the articular surface appears effective. Pin removal 4 weeks postoperatively appears adequate. Complications occurred with delayed presentation and non-compliance.

Abstract
PURPOSE The current literature describes multiple surgical and nonsurgical techniques for the management of mallet finger injuries, and there is no consensus on the indications for surgical treatment. The objective of this study was to determine, through a literature review, if any conclusions can be drawn concerning the indications for surgery in mallet finger injuries; the treatment outcomes of surgical versus nonsurgical management; the most effective methods of surgical and nonsurgical treatment; and the most common treatment complications of mallet finger injuries. METHODS A systematic review of multiple databases was performed. English language clinical studies evaluating therapeutic interventions for mallet fingers that reported objective, standardized outcome measures were included. Basic science studies, cadaveric studies, conference abstracts, level V evidence studies, studies lacking statistical data, and tendinous injuries other than mallet fingers were excluded. Salvage procedures and studies evaluating exclusively chronic lesions were also excluded. RESULTS Forty-four studies that reported clinical outcomes for the treatment of mallet finger injuries, 22 evaluating surgical treatments and 17 studies investigating nonsurgical treatments were included. The average distal interphalangeal joint extensor lag was 5.7° after surgical treatment and 7.6° after nonsurgical treatment. Complication rates of surgical and nonsurgical interventions were comparable (14.5% and 12.8%, respectively). Five studies directly compared the outcomes of surgical with nonsurgical management, with mixed results and recommendations. CONCLUSIONS Both surgical and nonsurgical treatments of mallet finger injuries lead to excellent clinical outcomes. Insufficient evidence is available to determine when surgical intervention is indicated. Based on our literature review, it appears that these treatments are equivalent and should be individualized to the patient. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Hand fractures (excluding small avulsion fractures and scaphoid fractures) almost always unite with bone. The role of the hand surgeon is not to achieve bone union but to achieve stability in an adequate position, often with some displacement, and maintenance of good soft tissue gliding. This article establishes that many fractures treated operatively do no better and often could not realistically do better than with good nonoperative treatment. Yet many are treated surgically to satisfy surgical egos, the desire to produce excellent radiographs, or just the mistaken belief that current surgical techniques can improve on nonoperative treatment.

Abstract
PURPOSE We aimed to compare the clinical and radiographic results of patients with a mallet fracture involving more than one-third of the articular surface, but without a high degree of distal interphalangeal (DIP) joint subluxation, treated with extension block pinning or nonsurgical management. METHODS Forty-nine patients with a mallet fracture involving more than one-third of the articular surface were reviewed. Twenty-six cases were treated using extension block pinning (surgery group) and 23 were treated nonsurgically (nonsurgical group). At the final follow-up, extension lag and flexion of the DIP joint of the affected digit were measured. Distal interphalangeal joint pain was rated using a visual analog scale and the overall clinical outcomes were graded using Crawford's criteria. Complications, including nail deformity and dorsal prominence, were also assessed. The rate of DIP joint subluxation and fracture fragment size were radiographically evaluated. RESULTS Mean extension lag and flexion of the DIP joint and mean visual analog pain scores were not significantly different in the 2 groups. Outcomes, as assessed using Crawford's criteria, were excellent in 5, good in 12, fair in 6, and poor in 3 in the surgery group, and excellent in 2, good in 11, fair in 8, and poor in 2 in the nonsurgical group. Moreover, the frequency of nail deformity or dorsal prominence was similar in the 2 groups. The rate of DIP subluxation and mean fracture fragment size were similar between the 2 groups. All the fractures had united by 3 months after injury in both groups. CONCLUSIONS The clinical outcomes do not significantly differ between extension block pinning and nonsurgical management for mallet fractures involving more than one-third of the articular surface, but without high degree subluxation of the DIP joint.

Abstract
Thumb injuries are common in athletes and present a challenging opportunity for upper extremity physicians. Common injuries include metacarpal base fractures (Bennett and Rolando types), ulnar and radial collateral ligament injuries, dislocation of the carpometacarpal and metacarpophalangeal joints, and phalanx fractures. This review, although not exhaustive, highlights some of the most common thumb injuries in athletes. The treating physician must balance pressure from athletes, parents, coaches, and executives to expedite return to play with the long-term well-being of the athlete. Operative treatment may expedite return to play; however, one must carefully weigh the added risks involved with surgical intervention.

Abstract
Phalangeal fractures are the most common type of hand fracture that occurs in the pediatric population and account for the second highest number of emergency department visits for fractures in the United States. The incidence of phalangeal fractures is the highest in children aged 10 to 14 years, which coincides with the time that most children begin playing contact sports. Younger children are more likely to sustain a phalangeal fracture in the home setting as a result of crush and laceration injuries. Salter-Harris type II fractures of the proximal phalanx are the most common type of finger fracture. An unmineralized physis is biomechanically weaker compared with the surrounding ligamentous structures and mature bone, which makes fractures about the physis likely. A thorough physical examination is necessary to assess the digital cascade for signs of rotational deformity and/or coronal malalignment. Plain radiographs of the hand and digits are sufficient to confirm a diagnosis of a phalangeal fracture. The management of phalangeal fractures is based on the initial severity of the injury and depends on the success of closed reduction techniques. Nondisplaced phalanx fractures are managed with splint immobilization. Stable, reduced phalanx fractures are immobilized but require close monitoring to ensure maintenance of fracture reduction. Unstable, displaced phalanx fractures require surgical management, preferably via closed reduction and percutaneous pinning.

Abstract
The aim of this study was to compare the clinical and radiological outcomes of one or two dorsal pins for extension blocking of mallet fractures. We treated 36 mallet fractures with the extension block technique. A single pin was used in 19 fractures (Group 1) and two pins in 17 fractures (Group 2). The mean age was 33.6 years and the mean follow-up time was 12.2 months. All patients were assessed by the Crawford outcome score. Extensor lag and other complications were noted. All fractures united with a mean time of 6.0 weeks (4-9) in Group 1, and 6.1 weeks (4-7) in Group 2. We obtained 74% and 71% excellent and good outcome scores in Group 1 and in Group 2, respectively. The final extension lag was 6° in Group 1, and 7° in Group 2. No difference was found between the two groups in terms of clinical outcomes, radiological values and complications.Level 3 non-randomized controlled study.

Abstract
Twenty-four mallet fractures which involved at least one third % of the articular surface of the distal interphalangeal joint were treated by open reduction and internal fixation using a single double-ended Kirschner wire at a mean of 9 days after injury (range 4–15). At a mean follow-up of 43 (range 12–18) months the active range of motion, pain and the Warren and Norris criteria were evaluated. The mean active range of motion was from −2° extension (range 0–10°) to 72° flexion (range 50–90°). Nineteen patients were pain free and five suffered from mild pain during strenuous work. The Warren and Norris results were successful in 22 and improved in two cases. Radiographs showed, that all the fractures united in a near-anatomic position but with joint narrowing in six digits.

Abstract
Over a period of 8 years, 48 fingers with mallet fractures of Wehbé and Schneider Types 1 and 2, subtypes B and C, were treated in 31 men and 17 women of mean age 42 (range 17–61) years. The fractures included 5 Type 1 subtype B, 2 Type 1 subtype C, 23 Type 2 subtype B and 18 Type 2 subtype C fractures. The technique used consisted in passing a K-wire percutaneously from dorsal to volar and pinning the fracture fragment while leaving the distal interphalangeal joint free to allow immediate postoperative mobilisation. Fracture splintage was removed at 6 weeks. The results at 8 weeks, which remained unchanged at 12 months in 46 fingers, were assessed as excellent in 11, good in 35 and fair in two cases by the Crawford rating system. One case of pin track infection required early removal of the pin.

Abstract
In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ) hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

J Hand Surg Eur Vol 2015; 40:832-9. [PMID: 25881978 DOI: 10.1177/1753193415581517] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2014] [Accepted: 03/21/2015] [Indexed: 02/03/2023]
Abstract
The aim of this retrospective study was to determine whether traumatic mallet fractures had better outcomes when treated by hook plate fixation (13 patients) or extension block pinning (19 patients). We assessed outcomes using Crawford's criteria; distal interphalangeal joint range of motion; the DASH score; and a visual analogue scale score for pain. We measured radiological parameters. No significant differences were observed in functional and clinical outcomes and in complications. Whereas the operative time was longer in the hook plate group, intraoperative fluoroscopy use, time to bone union and time to return to work were greater in the extension block group. Although the hook plate method is more technically demanding, it provides good stable reduction, earlier mobilization and an earlier return to work. The extension block pinning technique is easier and as effective but it requires greater peri-operative fluoroscopy. Level of evidence: Level III.

Abstract
PURPOSE To compare the outcomes and associated costs of the treatment of mallet fractures with either extension block pinning or open reduction and hook plate fixation. METHODS We treated 22 patients for a mallet fracture that involved at least 25% of the distal phalanx articular surface. Three joints demonstrated concomitant volar subluxation. Extension block pinning was used to treat 16 fractures (group 1) and 6 were treated with open reduction and hook plate fixation (group 2). All patients were evaluated at the second, fourth, and sixth weeks after surgery. Collected data included range of motion, extensor lag, and pain status. Patients were asked to grade preoperative and postoperative pain levels on a visual analog scale. Functional outcomes were determined by Crawford criteria. We retrospectively performed a cost analysis using our institutional records. RESULTS Mean follow-up was 12.7 months. Visual analog scale pain scores improved by a similar amount for both groups. Preoperative pain scores were 7.0 for group 1 and 7.5 for group 2. Postoperative levels were 2.0 and 2.0, respectively. Mean extensor lag was identical for both groups, 5°. Mean flexion was 70° for group 1 and 80° for group 2. Based on the Crawford criteria, group 1 had 5 patients rated as excellent, 6 as good, 3 as fair, and 2 as poor. Group 2 outcomes were 2 excellent, 2 good, and 2 fair. Five complications occurred in group 1, and 1 in group 2. Differences noted between groups were not statistically significant. Extension block pinning was more cost-effective than hook plate fixation. CONCLUSIONS We find extension block pinning to be an equally effective but more cost-efficient treatment than open reduction and hook plate fixation. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic III.

Abstract
Most hand fractures can be treated non-operatively. Some hand fractures, such as open injuries or markedly displaced intra-articular fractures, are almost always treated operatively. The treatment of many fractures, such as proximal interphalangeal joint fracture subluxations or spiral phalangeal fractures, is unclear. The aim of this review is to establish those injuries where the outcome of non-operative treatment is unlikely to be improved with surgery. This may help to prevent unnecessary surgery, concentrate work on finding the sub-groups that may benefit from surgery and to establish which injuries do so well with non-operative treatment that the only valuable clinical research in future will be large cohort studies of non-operative treatment or randomized controlled trials comparing operative and non-operative treatments. The relevant fractures are spiral metacarpal fractures, transverse metacarpal shaft and neck (boxer's) fractures, base of proximal phalanx avulsion fractures, thumb metacarpophalangeal joint ulnar and radial collateral ligament injuries and bony mallet injuries. For the majority of these injuries, current knowledge suggests that the outcome of non-operative treatment cannot reliably be improved upon with surgery.

Abstract
One-third of all mallet fingers are associated with a fracture. Mallet fractures associated with large fracture fragments may result in volar subluxation of the distal phalanx. The management of mallet fractures varies based on injury pattern and surgeon preference. These treatment options include splinting regimens, closed reduction and percutaneous pinning and open reduction and internal fixation. Although numerous surgical techniques have been described, there is little clear consensus on operative treatment. Moreover, there is insufficient evidence to support operative over nonoperative treatment for mallet fractures.

Abstract
BACKGROUND The treatment of mallet fractures is a controversial and challenging problem. Generally, mallet fractures are treated conservatively except those involving more than one third of the base of the distal phalanx. Many different surgical fixation techniques have been published. This paper describes a new fixation procedure using ultimate bioresorbable meniscal fixation nails (Meniscus Arrows®). METHODS Mallet fractures in 50 digits of 49 patients were fixed with this nail in an outpatient surgical procedure, mostly under local (Oberst-block) anaesthesia. The average operation time was 21 min. RESULTS According to the Crawford criteria, patient outcome was graded as excellent in 48 %, good in 22 %, and fair in 28 %. In one patient, the outcome was graded as poor, but the fracture was in a pre-existent arthritic joint. All fractures were consolidated without recurrent dislocation. Complications included one wound infection, which was successfully treated with antibiotics and without further consequences. No nail deformities occurred. Two times, the nail spontaneously and gradually dislocated during intensive use of the hand after, respectively, 3 and 6 months and could easily be removed under local anaesthesia without any functional sequelae. CONCLUSION The bioresorbable meniscal nail fixation technique provides a fast and successful surgical treatment for mallet fractures with a minimum of adverse events.

Abstract
PURPOSE To determine if transtendinous wiring was an effective late treatment for bony mallet injuries. METHODS Between 2005 and 2011, 19 consecutive patients (13 men, 6 women) with a mean age of 29 years (range, 13-52 y) were treated late for mallet finger fractures. The mean interval from injury to initial operation was 57 days (range, 28-141 d). RESULTS Fifteen of 18 mallet fractures demonstrated evidence of radiographic healing after an average of 6 weeks (range, 5-10 wk). One patient developed ankylosis, and 3 patients failed to achieve bone union at the final follow-up. The mean motion of the distal interphalangeal joint was 73° (range, 35°-95°), and the mean extension lag was 7° (range, 0°-25°). CONCLUSIONS Transtendinous wiring was an effective late treatment for mallet fractures, demonstrating satisfactory fixation, allowing early mobilization, and showing good functional results while avoiding salvage operations.

Abstract
Extensor mechanism injuries are frequently encountered in athletes and can lead to permanent disability or deformity if not promptly and properly treated. This article reviews basic anatomy, and then discusses mallet finger injuries, boutonniere deformity, and sagittal band rupture. Once treatment has begun, return to sport is highly variable because of the varied needs of each athlete and where they fall on the spectrum of disease. As such, each athlete must be carefully evaluated and closely followed to ensure a safe, prompt, and judicious return to athletic pursuits.

Abstract
Eleven patients with chronic mallet fractures that were seen later than four weeks after injury were treated by extension-block Kirschner wire technique. The average duration from injury to operative treatment was 56 days (range, 28–111). The follow-up evaluations took place after a mean of eight months. The radiographic bone union was obtained in all patients. The average extension loss of the DIP joint was 4 degree (range, 0–15) and the average flexion was 68 degree (range, 43–90). The results according to Crawford's criteria were six excellent, two good, two fair, and one poor. We would say that the technique we treated is effective method of treatment for younger patients with chronic mallet fractures.

Abstract
INTRODUCTION Various surgical treatments such as extension block pinning have been proposed for acute bony mallet finger. We evaluated the clinical results of tension wire fixation technique for the treatment of nonunion of mallet fracture after failed mallet finger surgery. MATERIALS AND METHODS Nine male patients were treated with open tension wire fixation for chronic nonunion of mallet fracture after extension block pinning surgery failed. The mean age was 29.3 years (range 18-47). We assessed bone union in simple radiographs. Crawford's and Bischoff functional score was used to assess the functional outcome. RESULTS The mean follow-up period was 45.8 months (range 18-74). Clinical and radiographic bone unions were achieved in eight of nine patients with average time of 31 days (range 23-41). Mean extension lag at final follow-up was 7° (range 0-25). Four patients showed excellent, three patients showed good and two patients showed fair results on the Crawford's score scale. With Bischoff functional score, all patients were categorized as excellent. CONCLUSIONS Tension wire fixation can be a good second-line reconstructive surgery for the treatment of mallet fracture after extension block failed, so that patients can avoid arthrodesis or complex tendon transfer as a salvage procedure.

Abstract
We prefer wide-awake finger fracture reduction, closed percutaneous K-wire fixation, and early protected movement to treat phalangeal fractures. This approach allows intraoperative visualization of active movement after K-wire fixation with the possibility of adjustments during the case. It also negates the need for extensive dissection with subsequent scar formation between the tendons and the bone. It provides the same advantages that are provided by early protected movement after flexor tendon repair.

Abstract
Pediatric hand fractures are common childhood injuries. Identification of the fractures in the emergency room setting can be challenging owing to the physes and incomplete ossification of the carpus that are not revealed in the radiographs. Most simple fractures can be treated with appropriate immobilization through buddy taping, finger splints, or casting. If correctly diagnosed, reduced, and immobilized, these fractures usually result in excellent clinical outcomes.

Abstract
INTRODUCTION To identify the strongest peak load resistance among four mallet finger fracture fixation methods (Kirschner wire, pull-out wire, tension-band wiring and the JuggerKnot™ (Biomet) soft anchor fixation). METHODS Fixation techniques were assigned among 24 specimens from six cadaveric human hands in a randomized block fashion. Peak load resistance was tested at 30°, 45° and 60° of flexion of the distal interphalangeal joint. RESULTS The mean peak load of tension-band wiring was 67.8 N at 60° of flexion which was most superior. The JuggerKnot™ fixation had mean peak loads of 13.35 N (30°), 22.51 N (45°) and 32.96 N (60°). No complications of implant failure or fragmentation of the dorsal fragment was noted. CONCLUSIONS Tension-band wiring was the strongest fixation method but was most prominent on the skin surface as seen in three specimens. The JuggerKnot™ soft anchor fixation had similar peak load resistance as k-wire fixation and pull-out wiring.

Abstract
Purpose: To report the outcomes of mallet fractures treated with our modified tension band wiring technique. Methods: Eleven men and two women (mean age; 33 years) with mallet fractures in which happened more than five weeks before surgery, or with fracture fragments involving more than 2/3 or less than 1/3 of the distal phalanx articular surface or with previous surgical intervention, were subjected to this study. The fracture fragment was fixed with a modified tension band wiring technique using a stainless steel wire and an injection needle. Results: All patients achieved bone union in nine weeks in average. All patients had no pain except one with mild pain. No patient showed a gap or step-off greater than 1 mm. Conclusions: Our tension band wiring technique can be used regardless of the size of the dorsal fracture fragment or the interval between injury and surgery.

Abstract
Mallet finger is a common injury involving either an extensor tendon rupture at its insertion or an avulsion fracture involving the insertion of the terminal extensor tendon. It is usually caused by a forceful blow to the tip of the finger causing sudden flexion or a hyperextension injury. Fracture at the dorsal aspect of the base of the distal phalanx is commonly associated with palmar subluxation of the distal phalanx. Most mallet finger injuries are recommended to be treated with immobilisation of the distal interphalangeal joint in extension by splints. There is no consensus on the type of splint and the duration of use. Most studies have shown comparable results with different splints. Surgical fixation is still indicated in certain conditions such as open injuries, avulsion fracture involving at least one third of the articular surface with or without palmar subluxation of the distal phalanx and also failed splinting treatment.

Abstract
Mallet injuries are the most common closed tendon injury in the athlete. Flexor digitorum profundus ruptures are rare in baseball, but are common injuries in contact sports. The diagnosis for each condition is based on clinical examination, although radiographs should be evaluated for a possible bony component. Treatment for mallet injury depends on the athlete's goals of competition and understanding of the consequences of any treatment chosen. Gripping, throwing, and catching would be restricted or impossible with the injured finger immobilized. Treatment of FDP ruptures is almost always surgical and requires reattachment of the torn tendon to the distal phalanx.
