Overview

• Absolute indications for surgical intervention for mallet fingers in pediatric populations remain unclear [1].
• Delayed surgical management of bony mallet fingers demonstrated adequate functional outcomes with minimal complications compared with prior literature [2].
• Both surgical and nonsurgical treatments of mallet finger injuries lead to excellent clinical outcomes [3].
• Most authorities splint only the distal joint for mallet finger deformities [4].
• Complication rates for large-fragment mallet finger cases are low, suggesting they can be effectively managed conservatively [5].
• Most mallet finger injuries can be managed non-surgically with splinting, although surgery is occasionally recommended for acute or chronic cases or for salvage of failed prior treatment [6].
• The role of surgery for mallet fractures of the thumb remains unclear due to their uncommon nature and favorable radiographic findings [7].
• After a mallet-finger injury treated within two weeks by either splinting method, few patients have significant persistent disability [8].
• Some authors propose treating all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which is treated with extra-articular pinning [9].
• The conservative treatment of mallet finger with a simple splint is recommended as an alternative means of treatment [14].
• There was insufficient evidence from comparisons tested within randomised controlled trials to establish the relative effectiveness of different, either custom-made or off-the-shelf, finger splints used for treating mallet finger injury [15].
• Surgery is generally indicated in the case of mallet fractures involving more than one-third of the articular surface as well as in all patients who develop volar subluxation of the distal phalanx [16].
• A significant advantage of surgical management even in complicated cases (fractures >1/3 articular surface or volar subluxation) has yet to be clearly proven [16].

Anatomy & Pathophysiology

• The mallet finger deformity is characterized by a loss of active distal interphalangeal (DIP) joint extension with full passive range of motion evident [18].
• The deformity reflects the loss of normal extensor force transmission via the terminal tendon insertion onto the distal phalanx [18].
• The unopposed flexor digitorum profundus pulls the distal joint into flexion [18].
• The usual mechanism of injury involves sudden passive flexion of an actively extended DIP joint [18].
• Disruption of the terminal tendon may be entirely confined to the tendon or may involve an avulsed fracture fragment from the dorsal lip of the distal phalanx proximal articular surface [18].
• The clinical appearance of soft tissue and bony mallet fingers is similar because the avulsed fragment includes the terminal tendon insertion [18].
• The distal joint rests in flexion, a posture that cannot be actively changed [18].
• Full passive extension of the DIP joint is possible [18].
• Mallet finger most commonly involves a closed rupture of the terminal tendon with or without associated fracture of the distal phalanx [34].
• Snagging the extending finger on an object that suddenly flexes the DIP joint is a frequent cause of injury [34].
• Less commonly, a forceful hyperextension injury of the DIP joint may result in a large fracture of the base of the distal phalanx involving one-third or more of the articular surface [34].
• Elderly patients with osteoarthritis of the DIP joint may have mallet deformities that are not related to trauma [34].
• Individuals with hyperlax joints may have multiple pseudomallet swan neck postures that are unrelated to trauma [34].
• Open mallet injuries are uncommon [34].
• The most frequently involved digits are the small, ring, and middle fingers of the dominant hand [34].
• There is a male predominance in mallet finger incidence [34].
• Tendinous mallet fingers have been reported to occur from age 11 onward [34].
• In skeletally immature individuals, a transepiphyseal plate fracture may be seen [34].
• There may be a familial predisposition to mallet fingers [34].
• The terminal tendon is the primary structure responsible for extending the DIP joint [46].
• Adjacent retinacular structures provide stability to the DIP joint [46].
• Palmar subluxation of a DIP joint without preexisting arthritic deformity is expected when more than one half of the dorsal articular surface is injured [47].
• A mallet finger caused by avulsion of the extensor tendon from the distal phalanx can be satisfactorily treated by splinting 12 weeks after injury [13].
• Prolonged splinting and splinting longer than 12 weeks may be successful, though the duration may be limited by the patient’s tolerance [13].
• After 12 weeks, if the distal phalanx droops severely but passive extension in the DIP joint is still satisfactory, surgery may be indicated depending on patient needs [13].
• Displacement of the epiphysis of the distal phalanx can cause the digit to assume a mallet finger posture [13].
• Hyperextension of the phalanx usually affords satisfactory reduction of a displaced epiphysis [13].

Classification

• Most mallet finger injuries can be managed non-surgically with splinting [6].
• Surgery is occasionally recommended for acute or chronic cases of mallet finger [6].
• Surgery is occasionally recommended for salvage of failed prior treatment of mallet finger [6].
• The authors propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger [9].
• Stage IV mallet finger is treated with extra-articular pinning [9].
• A modification to the Doyle classification is proposed to make it more encompassing and less prone to interobserver error [31].
• The interrater reliability of the Kellgren & Lawrence classification system for post-traumatic osteoarthritis in the distal interphalangeal joint after mallet finger fractures is considerably lower than initially assumed [36].
• The interrater reliability of the OARSI classification system for post-traumatic osteoarthritis in the distal interphalangeal joint after mallet finger fractures is considerably lower than initially assumed [36].
• The modified Mallet classification demonstrated strong to excellent agreement and interrater reliability across face-to-face, live tele-assessment, and video-based conditions [37].
• The modified Mallet classification is appropriate for remote medical follow-up [37].
• Non-operative management of mallet fractures is safe regardless of fracture classification [38].
• Non-operative management of mallet fractures is safe regardless of joint congruence [38].
• Non-operative management of mallet fractures is safe regardless of pre-existing degenerate change in the DIP joint [38].

Clinical Presentation

• Mallet finger injuries are frequent in football [19].
• Mallet deformity accounts for a minority of sporting injuries [28].
• Bilateral mallet fingers raise questions regarding the possible role of biochemical abnormalities in causing the condition [20].
• Approximately 50% of patients with a mallet fracture involving more than one-third of the articular surface of the distal phalanx do not progress to subluxation of the distal interphalangeal (DIP) joint [21].
• Fracture size is an independent risk factor for the development of DIP joint subluxation in mallet fracture [21].
• Time to application of a finger immobilizer is an independent risk factor for the development of DIP joint subluxation in mallet fracture [21].
• Conservative management of tendinous mallet finger injuries neglected for 2 to 4 weeks can be treated as well as those presenting within the first 2 weeks of injury, with low long-term complication rates [12].
• Surgery is occasionally recommended for acute or chronic cases of mallet finger or for salvage of failed prior treatment [6].
• Uncomplicated cases of mallet injuries are best treated by splinting therapy [29].
• Cases that do not react to splinting therapy are best treated by surgical interventions [29].
• The authors propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which is treated with extra-articular pinning [9].
• Early recognition of mallet finger injuries and referrals to a hand surgeon are crucial to avoid long-term disability [11].

Investigations

• Most authorities recommend splinting only the distal joint for mallet finger deformities [4].
• A radiograph should be obtained to determine whether a fracture is present [18].
• Radiographs should be evaluated to assess if the dorsal fragment is large and whether the distal phalanx is subluxed palmarward [18].
• Approximately 50% of patients with a mallet fracture involving more than one-third of the articular surface of the distal phalanx do not progress to subluxation of the DIP joint [21].
• Fracture size and time to application of finger immobilizer are independent risk factors for the development of DIP joint subluxation in mallet fracture [21].
• Surgery is generally indicated in cases of mallet fractures involving more than one-third of the articular surface [16].
• Surgery is generally indicated in all patients who develop volar subluxation of the distal phalanx [16].
• The advantage of surgical management for complicated cases (large fractures or subluxation) has yet to be clearly proven [16].

Treatment

Non-Operative Management

• Surgery is occasionally recommended for acute or chronic cases or for salvage of failed prior treatment [6].
• Conservative management of tendinous mallet finger injuries neglected for 2 to 4 weeks can be treated as well as those presenting within the first 2 weeks, with low long-term complication rates [12].
• A simple splint is recommended as an alternative means of treating mallet finger [14].
• There was insufficient evidence from randomized controlled trials to establish the relative effectiveness of different custom-made or off-the-shelf finger splints for treating mallet finger injury [15].
• Supplemental night splinting does not improve outcomes in terms of extensor lag, disability, or satisfaction with treatment [22].
• A hand therapist can treat type 1 mallet finger injuries as effectively as a surgeon [24].
• A hand therapist can treat type 1 mallet finger injuries as effectively as a surgeon, using an immobilization method that offers practically no complications regarding skin condition [32].
• Hand therapists implement a diverse range of clinical skills to optimize outcome success [23].
• The clinical efficacy of elastic taping for the treatment of mallet finger injuries remains to be tested vigorously [27].

Operative Management

• A significant advantage of surgical management over conservative management in complicated cases (fracture >1/3 articular surface or volar subluxation) has yet to be clearly proven [16].
• Surgical management may be considered for acute and chronic mallet lesions in patients who have failed nonsurgical treatment [30].
• Surgical management may be considered for acute and chronic mallet lesions in patients unable to work with the splint in position [30].
• Surgical management may be considered for acute and chronic mallet lesions in patients with a fracture involving more than one third of the joint surface [30].
• A deepithelialised pedicled skin flap technique is a new reliable alternative in the treatment of chronic mallet finger [25].
• Scar overlapping suture for treating chronic tendinous mallet finger in children is safe and effective [33].

Surgical Technique Details

• A mallet finger caused by avulsion of the extensor tendon from the distal phalanx can be satisfactorily treated by splinting 12 weeks after injury, as described for an acute injury [13].
• Prolonged splinting and splinting longer than 12 weeks may be successful, though duration may be limited by patient tolerance [13].
• After 12 weeks, if the distal phalanx droops severely but passive extension in the distal interphalangeal joint is still satisfactory, surgery may be indicated depending on patient needs [13].
• For surgical repair of chronic mallet finger, make a small V-shaped or U-shaped incision, convex distally, with the tip no closer than 5 mm proximal to the nail base on the dorsum of the finger [13].
• Avoid injury to the germinal matrix of the nail during incision for chronic mallet finger repair [13].
• Develop the flap gently in the plane between the tendon and subcutaneous fat, elevating proximally to expose the extensor tendon with intervening scar [13].
• Attempt to identify the junction of normal tendon with scar and sever the tendon transversely proximal to the joint, leaving the insertion of the tendon into bone [13].
• Resect sufficient scar or tendon to allow closure of the gap with the finger in maximal extension [13].
• Support and protect the repair by immobilizing the joint with a transarticular 0.045-inch Kirschner wire [13].
• Repair the extensor tendon with 4-0 monofilament nylon or 4-0 monofilament wire as a pull-out roll stitch [13].
• No additional sutures are required for the tendon repair in chronic mallet finger surgery [13].
• Close the skin with interrupted 5-0 nylon or use 4-0 nylon as a dermotondermal suture [13].
• Maintain the finger in extension and apply a compressive dressing post-operatively [13].
• Support the finger with a volar splint for post-operative comfort and to avoid reinjury in the recovery period [13].
• Sutures are removed at 10 to 14 days post-operatively [13].
• The distal joint is maintained in extension, with the Kirschner wire protected by a small metal splint, for 4 weeks post-operatively [13].
• The Kirschner wire is removed after 4 to 6 weeks post-operatively [13].
• The repair is protected with a splint for 8 weeks post-operatively [13].
• Normal activities are progressively resumed after the post-operative protocol [13].

Complications

• Delayed surgical management of bony mallet fingers demonstrated minimal complications [2].
• Conservative management of neglected tendinous mallet finger injuries (2 to 4 weeks) is associated with low long-term complication rates [12].
• Large-fragment mallet finger cases managed conservatively have low complication rates [5].
• Surgical treatment of acute combined tendon and bone (double level) mallet finger injuries reported no complications such as infection, nonunion, or nail deformity [17].
• The complication rate after operative treatment of mallet fracture was 41% [41].
• The high complication rate in operative treatment of mallet fracture is likely attributable to anatomical factors such as thin extensor tendon and poor blood supply [41].

Recovery

• Delayed surgical management of bony mallet fingers demonstrates adequate functional outcomes with minimal complications compared with prior literature [2].
• Large-fragment mallet finger cases can be effectively managed conservatively with low complication rates [5].
• All cases of mallet finger are proposed to be treated with a dorsal glued splint except for stage IV mallet finger, which is treated with extra-articular pinning [9].
• Early recognition of tendon rupture injuries and referrals to a hand surgeon are crucial to avoid long-term disability [11].
• Surgical treatment of acute combined tendon and bone (double level) mallet finger injuries using pullout wire fixation with distal interphalangeal joint Kirschner wire stabilization reports good to excellent long-term results with no reported complications such as infection, nonunion, or nail deformity [17].
• Mallet finger injuries are frequent in football and difficult to treat during the competitive season, often requiring delayed treatment or internal splinting [19].
• Supplemental night splinting does not improve the outcome of mallet finger in terms of extensor lag, disability, or satisfaction with treatment [22].
• The Fowler procedure is the safest and most effective reconstructive measure for chronic mallet finger deformity after phalangeal fracture, offering less morbidity than osteotomy or procedures restraining proximal interphalangeal joint extension [44].
