RESUMO
The conventional hand tendon zones and subzones do not reflect the actual lengths covered by the involved locus of the tendon during full digital and wrist motion, which warrant reappraisal of the tendon zone concept. Because of the tendon excursions many lacerations should be regarded as multiple zone injuries. Furthermore, the length-spans of glide of the distal tendon stump and of the tendon junction (i.e. the glide zones of tendon injury and repair, respectively) are mostly not of the same length because, due to pulley release and bulkiness of the tenorrhaphy, the glide zone of tendon repair is shorter than that of tendon injury. Therefore, it would be practical to notate the glide zones of the lacerated tendon by indicating the anatomic position of the distal tendon stump and tendon junction in full extension and flexion. This data can be provided separately or along with the conventional tendon zones, e.g. II (A4-C2) or II-III (A2-PA), where A, C, and PA stand for the annular, cruciform, and palmar aponeurosis pulleys, respectively. The conventional tendon zone classification could be improved with a tendon glide zone concept. Documentation of the actual excursions of the distal tendon stump and of the tenorrhaphy interface would prevent misinterpretation of the actual level of tendon injury and repair.

Mallet finger injuries are a common presentation in the emergency department. These injuries result from a forced flexion at the distal interphalangeal joint (DIPJ) that causes extensor tendon disruption, and possibly bone avulsion, at the base of the distal phalanx. This article describes the anatomy, mechanisms, classification and assessment of mallet finger injury. It reviews different types of splints used in the conservative management of closed tendinous mallet finger injury and discusses the latest evidence regarding immobilisation methods and treatment duration. Maintaining the DIPJ in extension during treatment is essential, so the article stresses the importance of patient adherence to treatment.

BACKGROUND: Mallet fracture is avulsion of the terminal extensor tendon from the base of the distal phalangeal bone with a bony fragment. This study was performed to evaluate the anatomical characteristics of mallet fractures, investigate a new mallet fracture classification system using anatomical and imaging methods, and discuss the treatment schemes for different types of mallet fracture. METHODS: Sixty-four fresh cadaveric fingers were divided into four groups, and models of different types of mallet fracture with distal interphalangeal joint instability were established by dissecting 25%, 50%, 75%, and 100% of the bilateral collateral ligaments. The effect of mallet fractures on the stability of the distal interphalangeal joint was then observed. The lateral radiographs of mallet fractures in 168 patients were analyzed and classified according to the involvement of the joint surface in the fracture, the thickness of fracture, the untreated time after injury, and the complication of distal interphalangeal joint palmar subluxation. Forty-seven patients were surgically treated by reconstruction of extensor tendon insertion, the Ishiguro method, or single Kirschner wire fixation. RESULTS: The established mallet fracture model showed that the distal interphalangeal joint was stable when the bilateral collateral ligaments were cut off by 25% (tâ=â-0.415, Pâ=â0.684) and significantly unstable when this range was ≥50% (50% transection: tâ=â-6.363, Pâ<â0.001; 75% transection: tâ=â-17.036, Pâ<â0.001; 100% transection: tâ=â-30.977, Pâ<â0.001, respectively). The mallet fractures were divided into Types I, II, and III (fracture involving <20%, 20%-50%, and >50% of the joint surface, respectively). Type II was further divided into Types IIa and IIb according to whether the course of injury was < or ≥2 weeks, respectively. The mean post-operative flexion of the distal interphalangeal joint was 63.4°â±â7.9°, and the mean extension lag was 6.7°â±â4.6°. CONCLUSIONS: The lateral collateral ligament is the main factor that maintains the stability of the distal interphalangeal joint. Classification that combines the involvement of the joint surface in the fracture, the thickness of the fracture, and the untreated time after injury is reasonable and will help to choose an appropriate operational method.

Importance: Optimal treatment for traumatic finger amputation is unknown to date. Objective: To use statistical learning methods to estimate evidence-based treatment assignment rules to enhance long-term functional and patient-reported outcomes in patients after traumatic amputation of fingers distal to the metacarpophalangeal joint. Design, Setting, and Participants: This decision analytical model used data from a retrospective cohort study of 338 consenting adult patients who underwent revision amputation or replantation at 19 centers in the United States and Asia from August 1, 2016, to April 12, 2018. Of those, data on 185 patients were included in the primary analysis. Exposures: Treatment with revision amputation or replantation. Main Outcomes and Measures: Outcome measures were hand strength, dexterity, hand-related quality of life, and pain. A tree-based statistical learning method was used to derive clinical decision rules for treatment of traumatic finger amputation. Results: Among 185 study participants (mean [SD] age, 45 [16] years; 156 [84%] male), the median number of fingers amputated per patient was 1 (range, 1-5); 115 amputations (62%) were distal to the proximal interphalangeal joint, and 110 (60%) affected the nondominant hand. On the basis of the tree-based statistical learning estimates, to maximize hand dexterity or to minimize patient-reported pain, replantation was found to be the best strategy. To maximize hand strength, revision amputation was the best strategy for patients with a single-finger amputation but replantation was preferred for all other injury patterns. To maximize patient-reported quality of life, revision amputation was the best approach for patients with dominant hand injuries, and replantation was the best strategy for patients with nondominant hand injuries. Conclusions and Relevance: The findings suggest that the approach to treating traumatic finger amputations varies based on the patient's injury characteristics and functional needs.

When bone is exposed, fingertip defects may require a flap procedure. Many types are available, with little consensus about which one is best. But each one has its own disadvantages: esthetic (claw nail deformity), neurological (sensory disorders) or functional (stiffness). The purpose of this study was to evaluate a palmar bipedicular island flap (our modification of the Tranquilli-Leali flap) for fingertip reconstruction. We retrospectively analyzed the prospective data of 42 patients with a mean follow up of 16.4 months (6-30 months) operated in two hospital facilities. Thirty-three patients were men. Mean age was 39.5 years (12-83 years) and 24 (57.1%) were smokers. In 23 cases (54.8%), the trauma was work-related. A crush mechanism was identified in 29 patients (69%). According to Allen's classification of fingertip injuries, there were 26 cases of stage II, 14 cases of stage III and 2 cases of stage IV. All procedures were performed on an emergency basis, within 24 hours of the trauma. No claw nail deformity was observed. The mean discrimination in the Weber test was 3.8mm (2-6mm). The mean Total Active Motion (TAM) was 268.3° (255-275°). The patient satisfaction was graded at 8.7 on a 10-point scale. Results were considered as excellent in 15 cases and good in 23 cases. The modified palmar bipedicular island flap makes the old Tranquilli-Leali flap - which has a poor reputation in the hand surgeon community-simpler and safer to use. This flap restores proper balance between skin, bone and nail in Allen stage II and III fingertip amputations.

BACKGROUND: We proposed a new system named the sagittal, coronal, axial, rotational and fracture (SCARF) classification, which can simply explain any condition of proximal interphalangeal (PIP) joint dislocations of the fingers. The purpose of this study was to verify that this classification would contribute to management of PIP joint dislocations at the initial therapy. We determined ratios of five factors in PIP dislocations with SCARF by interpreting radiographs and assessed the interobserver and intraobserver variability. METHODS: In total, 68 fingers in 67 consecutive patients were studied. The SCARF classification is composed of five factors: (1) sagittal plane displacement is rated by dorsal (D), volar (V), or neutral (N); (2) coronal plane displacement, by ulnar (U), radial (R), or neutral (N); (3) axial force, by compression (C), traction (T), or no (N); (4) rotational displacement, by supine (S), prone (P), or neutral (N); and (5) fracture concomitance, by minus (-) or plus (+). The row of the five characters explains each condition of PIP joint dislocations. Interobserver and intraobserver variability was determined after six orthopedic surgeons independently classified the same radiographs twice. RESULTS: All 68 dislocations were classified into 14 types, unless fracture concomitance was considered. The most common type was DUNN (35%). In coronal plane displacements, the two ulnar fingers showed a higher tendency to the ulnar position. Ring finger fracture concomitance was higher than in middle fingers or little fingers. In interobserver analysis, mean kappa coefficient for each factor was 0.63, 0.75, 0.68, 0.33, and 0.84, respectively. In intraobserver analysis, that was 0.73, 0.79, 0.71, 0.41, and 0.81, respectively. CONCLUSIONS: Even other than hand specialists can specify the type of every PIP dislocation by using the SCARF classification and will have better understanding of the disorder. It would contribute to management of PIP dislocations at the initial therapy. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

Proximal interphalangeal joint injuries are one of the most common injuries of the hand. The severity of injury can vary from a minor sprain to a complex intra-articular fracture. Because of the complex anatomy of the joint, complications may occur even after an appropriate treatment. This article provides a comprehensive review on existing techniques to manage complications and imparts practical points to help prevent further complications after proximal interphalangeal joint injury.

Due to the exposure of the hands in the daily routine, defect wounds of the hand are common. The injury severity varies and ranges from small fingertip defects to large soft tissue lesions with exposed tendons, nerves and vessels. The complete extent of the soft tissue defect is often only recognizable after meticulous debridement. A considerable variety of techniques for defect coverage are available to the surgeon but the actual challenge is to select the most appropriate procedure which will result in the smallest possible residual defect. This review article presents the diagnostic approaches to soft tissue defects of the hand and current treatment options.

Defects on the palmar surface of the fingers are an important part of hand emergencies, especially fingertip wounds. Luckily, many coverage methods are available. We will review the anatomy of this area and the thought process for treating these defects. We will also propose an algorithm that can be used to select the best technique based on the type of injury present.

The metacarpal-like hand is a severe hand injury, never addressed before. It describes a hand that has lost a significant degree of prehension through a wide array of amputations, involving all digits proximal to the functional length except in one finger or in two digits, including the thumb. The thumb condition can be used to differentiate between two types. In type I, the thumb is intact or amputated at or distal to the interphalangeal joint (functional length); therefore, the reconstruction is focused mainly on fingers. In type II, the thumb is amputated proximal to the interphalangeal joint; therefore, the reconstruction is focused on both the thumb and fingers. Thumb amputation level, integrity of the first basal joint, and functionality of the thenar muscles can be used to subdivide type II. Functional reconstruction should consider the patient's desire and vocational needs. The finger left with adequate functional length is assessed for its location, level of amputation, and joint motion, especially the proximal interphalangeal joint. The goal is to use the reliable techniques of toe-to-hand surgery to reconstruct more opposable units, at least two fingers, whether adjacent to each other or not, and the thumb, when needed, to achieve a functionally and aesthetically better hand instead of a functionally adequate hand, with a more acceptable to ideally natural hand cascade. Strategic, individualized toe transfer(s) is the key element in fulfilling the goals of this operation whether single or multiple toes are transplanted.

BACKGROUND: Ring avulsion injuries can range from soft tissue injury to complete amputation. Grading systems have been developed to guide treatment, but there is controversy with high-grade injuries. Traditionally, advanced ring injuries have been treated with completion amputation, but there is evidence that severe ring injuries can be salvaged. The purpose of this systematic review was to pool the current published data on ring injuries. METHODS: A systematic review of the English literature published from 1980 to 2015 in PubMed and MEDLINE databases was conducted to identify patients who underwent treatment for ring avulsion injuries. RESULTS: Twenty studies of ring avulsion injuries met the inclusion criteria. There were a total of 572 patients reported with ring avulsion injuries. The Urbaniak class breakdown was class I (54 patients), class II (204 patients), and class III (314 patients). The average total arc of motion (TAM) for patients with a class I injury was 201.25 (n = 40). The average 2-point discrimination was 5.6 (n = 10). The average TAM for patients with a class II injury undergoing microsurgical revascularization was 187.0 (n = 114), and the average 2-point discrimination was 8.3 (n = 40). The average TAM for patients with a class III injury undergoing microsurgical revascularization was 168.2 (n = 170), and the average 2-point discrimination was 10.5 (n = 97). CONCLUSIONS: Ring avulsion injuries are commonly classified with the Urbaniak class system. Outcomes are superior for class I and II injuries, and there are select class III injuries that can be treated with replantation. Shared decision making with patients is imperative to determine whether replantation is appropriate.

Extension of the fingers is a complex act. Boutonnière deformity is defined by flexion at the proximal inter-phalangeal (PIP) joint and hyperextension at the distal interphalangeal (DIP) joint due to disruption of the central slip of the extensor tendon. Swan neck deformity is defined by hyperextension at the PIP joint and flexion at the DIP joint, and the pathology is divided into intrinsic, extrinsic, and articular. The deformities are a result of imbalance of the tendons and ligaments in the fingers. Treatment is depending on the underlying cause and includes surgery and non-operative treatment. Functional gain and risk must be realistically assessed.

Traumatic avulsion of flexor digitorum profundus (jersey finger) is an uncommon injury. Our study aimed to describe functional outcomes of jersey fingers after surgical treatment. From January 2004 to 2014, we performed surgery on 32 patients who had jersey finger. Twenty-six of these patients were male and 6 were female with a mean age of 37.2years (range 16-68). Of the 32 cases, 11 were sports injuries, 16 presented on the ring finger and 13 on the little finger. Using the Leddy and Packer and Smith classifications, 16 of the injuries were type I, 4 were type II, 5 were type III, 7 were type IV. The mean time between injury and surgery was 6.8days (range: 0-32). The surgical techniques used were anchor, pull-out, or an association of both these techniques. Prior to the patient discharge, functional outcomes were evaluated. Twenty-nine patients were evaluated in total and three patients were lost. Of the 29, the average time between surgery and discharge was 36.6months ranging from 4.5 to 118months. According to the Buck-Gramcko classification, six patients had an excellent result, six had a good result, seven had a satisfactory result and ten a poor result. The mean Quick DASH score immediately to prior discharge was 5.66 (range: 0-56.82). Twelve complications were reported on nine patients. No infections were reported. Rapid diagnosis and rapid surgical treatment led to restoration of full range motion.

BACKGROUND: Closed avulsion injury of the flexor digitorum profundus (FDP) tendon is a relatively common condition of the hand. Its present classification system seems to be deficient in including all possible patterns of injury, leading to improper selection of the best treatment method for the injury. We aim to provide a new classification scheme for this injury. METHODS: We developed a new classification scheme based on the possible pattern of FDP tendon injury. It consisted of three main types, and 10 sub-types. This was used to classify the injury of 34 patients, and help in choosing the best management approach. All patients underwent surgical treatment of their injury. The distal interphalangeal (DIP) joint extension deficit and total active motion (TAM) of the proximal interphalangeal (PIP) and DIP joints were considered as the main outcomes. Five orthopaedic surgeons used the new classification system for our cases, and the inter-rater reproducibility was tested with Fleiss' kappa. RESULTS: The multi-rater kappa for the classification was excellent. At the final follow-up visit 24 months following surgery, the mean loss of extension of the DIP joint was 13.76° ± 13.53° (range 0° to 45°), while the mean TAM was 148.88° ± 22.64° (range 94° to 172°). Based on the TAM score, 21 (61.76%), 8 (23.53%) and 5 (14.71%) patients had excellent, good and fair results, respectively. None of our patients had poor results. CONCLUSIONS: Our new classification scheme of FDP tendon avulsion appeared to be comprehensive and useful in guiding the surgeon for the best treatment option. Nevertheless, this should be confirmed by using it for larger number of patients with different patterns of injury.

STUDY DESIGN: Systematic review. INTRODUCTION/PURPOSE: The purpose of this study was to systematically review outcome measures used for the assessment of the conservative management of mallet finger to determine if they characterize the International Classification of Functioning, Disability, and Health components of activity, participation, environmental factors, or quality of life. METHODS/RESULTS: Five studies published within the last 10 years were included in the systematic review. A majority, 19 of the outcomes used by the authors, fell within the body functions and structures category. Six were related to activity, and 1 was related to participation. One was linked to environmental factors. Five were found to be not definable and related to quality of life. DISCUSSION/CONCLUSION: This systematic review suggests that many outcome measures focus on body structures and functions in the current research on the conservative treatment of mallet finger injuries. LEVEL OF EVIDENCE: 2a.

The objective of this study was to compare the functional outcomes of zone II amputations treated with either replantation or revision amputation at our institution to better aid patients in their decision making process regarding these treatment options. We conducted a comparative retrospective study. All cases of single digit amputations received at our replantation center between 2007 and 2011 were screened for single digit zone II injuries. These patients were stratified based on the treatment received: replantation vs revision amputation. Patients were called and invited to participate in the research project. Those who accepted to enter the study were asked to complete the Quick-DASH, the Beck Depression Inventory-short form, and a custom made questionnaire. There were seventeen patients with single digit zone II replantation and fourteen patients with similar injuries who underwent revision amputation and agreed to take part in the study. Our data revealed that the duration of sick leave, occupation after injury, professional and social reintegration, discontinued activities, and self-confidence were not statistically different between the two groups. The average hospital stay and the follow-up period of replanted individuals were longer. The replantation group did not have higher levels of pain or cold intolerance, and the global functional and esthetic satisfaction levels were similar between the two groups. Also, Beck Depression Inventory and Quick-DASH scores were not statistically different. Yet, significantly more patients in the replantation group would opt to repeat the replantation than revised patients would opt for revision amputation. From a functional viewpoint, our study suggests that revision amputation is not superior to replantation in zone II single digit amputations. This is valuable information that should be given to patients when deciding on the treatment process and to insure a proper informed consent.

PURPOSE: This study evaluated the composite graft survival rate in distal digital amputations with respect to injury type and amputation level. METHODS: Twenty-seven patients with complete fingertip amputations (32 digits) distal to the distal interphalangeal joint who were treated by composite grafting from January 2010 to February 2012 were enrolled. Injury type was classified as clean-cut, blunt-cut, or crush-avulsion. Amputation level was classified according to Ishikawa's classification: subzones I-IV. Graft survival was categorised as complete, partial, or no survival. RESULTS: The graft was more likely to exhibit complete survival in clean-cut injuries (50%) than in blunt-cut (10%) or crush-avulsion injuries (12.5%). However, when complete and partial survival were combined, there was no significant difference among injury types (clean-cut = 83.3%, blunt-cut = 70.0%; crush-avulsion = 68.8%). Composite grafting in sub-zone I provided good results (complete survival = 50%; partial survival = 50.0%; no survival = 0%). When complete and partial survival were combined, there was no significant difference with respect to amputation level except sub-zone I (II = 70.6%; III = 66.7%; IV = 60%). In sub-zone II, clean-cut injuries exhibited better graft survival than blunt-cut or crush-avulsion injuries. In sub-zones III and IV, no complete graft survival was observed. CONCLUSION: In conclusion, all types of injuries in sub-zone I and clean-cut injuries in sub-zone II are candidates for composite grafting. Blunt-cut and crush-avulsion injuries in sub-zone II are marginal candidates for composite grafting. Any type of injury in sub-zone III or IV is contraindicated for composite grafting and should be treated by microanastomosis.

Finger joint dislocations and collateral ligament tears are common athletic hand injuries. Treatment of the athlete requires a focus on safe return to play and maximizing function. Certain dislocations, such as proximal interphalangeal and distal interphalangeal volar dislocations, may be associated with tendon injuries and must be treated accordingly. Treatment of other dislocations is ultimately determined by postreduction stability, with many dislocations amenable to nonoperative treatment (ie, immobilization followed by rehabilitation). Protective splinting does not necessarily preclude athletic participation. Minor bone involvement typically does not affect the treatment plan, but significant articular surface involvement may necessitate surgical repair or stabilization. Percutaneous and internal fixation are the mainstays of surgical treatment. Treatment options that do not minimize recovery or allow the patient to return to protected play, such as external fixation, are generally avoided during the season of play. Undertreated joint injuries and unrecognized ligament injuries can result in long term disability.
