ਮੈਲੇਟ ਫਿੰਗਰ (Mallet Finger)

This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview¶

• Most mallet finger injuries can be managed non-surgically with splinting [6].
• Surgery is occasionally recommended for acute or chronic mallet finger cases or for salvage of failed prior treatment [6].
• Mallet fingers can be cured or significantly improved in approximately 50% of cases by simple splintage [3, 9].
• After a mallet-finger injury treated within two weeks by either internal or external splintage, few patients have significant persistent disability [8].
• Both surgical and nonsurgical treatments of mallet finger injuries lead to excellent clinical outcomes [7].
• There was insufficient evidence from randomised controlled trials to establish the relative effectiveness of different custom-made or off-the-shelf finger splints used for treating mallet finger injury [15].
• The perforated mallet finger splint can produce consistently good results even in patients who would not tolerate a conventional splint [33, 34].
• Compliant patients have significantly better outcomes than noncompliant patients in the treatment for mallet finger injuries [22].
• Specialist hand therapists could treat mallet finger by themselves, providing that the patients fit the inclusion criteria for non-operative treatment [17].
• The authors propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which they treat with extra-articular pinning [1].
• Absolute indications for surgical intervention for mallet fingers in the pediatric population remain unclear [2].
• Simple surgery such as Kirschner wire fixation of the DIP joint or tenodermodesis is of benefit in most patients with mallet finger who fail to be cured by simple splintage [11].
• Delayed surgical management of bony mallet fingers demonstrated adequate functional outcome with minimal complications when compared with prior literature [4].
• Complication rates were low, suggesting that large-fragment mallet finger cases can be effectively managed conservatively [5].
• 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 [46].
• A significant advantage of surgical management even in complicated mallet fracture cases has yet to be clearly proven [46].
• The role of surgery for mallet fractures of the thumb remains unclear due to their uncommon nature and favorable radiographic findings [18].
• Primary surgical repair is the preferred treatment for mallet thumb, but conservative treatment should be the first choice if there is no skin wound or the conditions at first consultation are not appropriate for surgery [32].
• Central slip tenotomy is the best choice for mallet finger deformity because of the minimal amount of time required to return to function [14].
• The authors recommend the central slip release as an alternative to reconstruction in certain types of chronic mallet finger deformity [24].
• A safe and simple technique for chronic mallet fingers is proposed if deformity exceeds 30°, for patients untreated after the second month, or when splinting has failed [13].
• Today most authorities splint only the distal joint for mallet finger deformities [10].

Anatomy & Pathophysiology¶

Anatomy¶

• The extensor apparatus of the fingers includes the interosseous muscle, extensor digitorum communis tendon, lumbrical muscle, flexor tendon sheath, sagittal bands, transverse metacarpal ligament, interosseous hood, interosseous hood oblique fibers, extensor lateral band, extensor middle band, interosseous middle band, interosseous lateral band, oblique retinacular ligament, central extensor lateral, spiral fibers, transverse retinacular ligament, lateral extensor tendon, triangular lamina, and terminal extensor tendon [27].
• The terminal extensor tendon inserts onto the distal phalanx [27].
• The mallet finger deformity reflects the loss of normal extensor force transmission via the terminal tendon insertion onto the distal phalanx [41].
• The unopposed flexor digitorum profundus pulls the distal joint into flexion in mallet finger deformity [41].
• Displacement of the epiphysis of the distal phalanx can cause the digit to assume a mallet finger posture [27].
• Hyperextension of the phalanx usually affords satisfactory reduction of a displaced epiphysis in mallet finger [27].

Pathophysiology¶

• Mallet finger involves loss of continuity of the extensor tendon over the distal interphalangeal joint [28].
• Mallet finger results in a flexion deformity of the distal finger joint [28].
• Mallet finger may lead to an imbalance between flexion and extension forces more proximally in the digit [28].
• The mallet finger deformity is characterized by a loss of active distal interphalangeal joint extension with full passive range of motion evident [41].
• The usual mechanism of injury involves sudden passive flexion of the actively extended distal interphalangeal joint [41].
• 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 [41].
• Because the avulsed fragment includes the terminal tendon insertion, the clinical appearance of soft tissue and bony mallet fingers is similar [41].
• The distal joint rests in flexion, a posture that cannot be actively changed in mallet finger [41].
• Full passive extension of the distal interphalangeal joint is possible in mallet finger [41].
• Mallet finger is due to a disruption of the extensor mechanism from its insertion at the dorsal base of the distal phalanx [57].
• Closed mallet injuries are usually from a sudden forced flexion of a previously extended distal interphalangeal joint [57].
• Mallet finger most commonly involves a closed rupture of the terminal tendon with or without associated fracture of the distal phalanx [91].
• Snagging the extending finger on a pants cuff, a bedsheet, or other object that suddenly flexes the extending distal interphalangeal joint is a frequent cause of mallet finger [91].
• A forceful hyperextension injury of the distal interphalangeal joint may result in a large fracture of the base of the distal phalanx involving one-third or more of the articular surface [91].
• Elderly patients with osteoarthritis of the distal interphalangeal joint may have mallet deformities that are not related to trauma [91].
• Individuals with hyperlax joints may have multiple pseudomallet swan neck postures that are unrelated to trauma [91].
• Open mallet injuries are uncommon [91].
• The most frequently involved digits in mallet finger are the small, ring, and middle fingers of the dominant hand [91].
• Mallet finger has a male predominance [91].
• Tendinous mallet fingers have been reported to occur from age 11 onward [91].
• In skeletally immature individuals, a transepiphyseal plate fracture may be seen in mallet finger [91].
• There may be a familial predisposition to mallet fingers [91].
• An epidemiologic survey of 24 members of a three-generation family revealed an unusually high incidence of mallet fingers [12].
• Twenty mallet fingers were found in seven family members by clinical examination, suggesting a familial predisposition to develop this deformity [12].
• Multiple mallet fingers occurred in the surveyed family, with a range of two to six per member [12].
• The term "mallet finger" refers to a disruption to the terminal extensor mechanism with a lack of full or active extension through the distal interphalangeal joint [53].
• The term "mallet finger" is a misnomer, as rarely do these digits actually resemble a mallet [53].
• Other descriptions for mallet finger injuries include "baseball finger," "cricket finger," and "drop finger" [53].
• The direction of force on the fingertip that results in a mallet fracture has yet to be determined [115].
• The precise mechanism of injury leading to different sizes of mallet fracture fragments might be difficult to delineate due to multiple variables, including tendon tension at the time of injury and the strain-rate-dependent mechanical properties of the affected bone and soft tissues [115].
• Distal interphalangeal joint subluxation is expected with a mallet fracture fragment involving more than one-half of the joint surface [115].
• The distal interphalangeal joint has a remarkable ability to remodel [115].

Classification¶

• The Doyle classification system describes four types of mallet finger injuries [119].
• In the Doyle classification, Type IV represents mallet fractures and is further broken into three subtypes according to the size of articular involvement [119].
• The Wehbe and Schneider classification describes DIP joint subluxation and epiphyseal and physeal injuries [119].
• In the Wehbe and Schneider classification, articular injuries are subdivided into type A (less than one-third), type B (between one-third and two-thirds), and type C (larger than two-thirds of the joint) [119].
• The Doyle classification is proposed to be modified to make it more encompassing and less prone to interobserver error [53].
• The modified Mallet classification demonstrated strong to excellent agreement and interrater reliability across face-to-face, live tele-assessment, and video-based conditions [113].
• The modified Mallet classification is suggested to be appropriate for remote medical follow-up [113].
• The interrater reliability of the Kellgren & Lawrence and OARSI classification systems for post-traumatic osteoarthritis in the distal interphalangeal joint after mallet finger fractures is considerably lower than initially assumed [102].
• There is a need for better randomized, prospective studies to separate the various types of mallet injuries and their treatments [31].

Clinical Presentation¶

• Mallet injuries can be classified into four types based on skin integrity and the presence or absence of bony involvement [28].
• The diagnosis of bony mallet finger is usually straightforward based on the patient’s history, typical findings observed on physical examination (i.e., drop finger deformity and lack of DIPJ extension) and identification of an avulsion fracture on lateral finger radiographs [66].
• Mallet finger is often associated with a dorsal fracture of the base of the terminal phalanx [67].
• In cases of mallet finger with fracture, the avulsed fragment is typically small [67].
• In cases of mallet finger with fracture, there may be hyperextension at the proximal interphalangeal joint [67].
• In some cases of dorsal basal fracture, the fragment is appreciably larger and widely separated but there is no dropping of the fingertip [67].
• In cases with a larger dorsal basal fragment and no dropping of the fingertip, there is no associated hyperextension at the proximal interphalangeal joint [67].
• In cases with a larger dorsal basal fragment and no dropping of the fingertip, there may be volar subluxation of the terminal phalanx [67].
• Bony mallet injuries are typically caused by hyperextension rather than hyperflexion [44].
• Mallet finger injuries are frequent in football [43].
• Mallet deformity accounts for a minority of sporting injuries [36].
• Multiple mallet fingers occurred in the surveyed family, with a range of two to six per individual [12].

Investigations¶

• A radiograph should be obtained to determine whether a fracture is present [41].
• If a fracture is present, a radiograph should determine whether the dorsal fragment is large and whether the distal phalanx is subluxed palmarward [41].
• The clinical appearance of soft tissue and bony mallet fingers is similar, with the distal joint resting in a flexion posture that cannot be actively changed [41].
• Full passive extension of the distal interphalangeal joint is possible in mallet finger deformities [41].

Treatment¶

Non-Operative Management¶

• Splinting of the distal interphalangeal joint for 6 to 8 weeks has yielded good results while minimizing morbidity in the majority of patients [28].
• Non-operative management of mallet fractures, regardless of fracture classification, joint congruence or pre-existing degenerate change in the DIP joint, is safe and yields predictably good outcomes in most patients [30].
• This study supports the rationale for nonsurgical treatment of closed and displaced mallet finger fractures with greater than one-third articular surface involvement [39].
• The author argues that mallet fractures can be treated by nonoperative methods, stating that nonoperative treatment provided good results without the need for manipulation, open or closed, and without the use of pins [99].
• Conservative management of tendinous mallet finger injuries that have been neglected for 2 to 4 weeks can be treated as well as those injuries in patients presenting within the first 2 weeks of injury with low long-term complication rates [38].
• A hand therapist can treat mallet finger injuries of type 1 as effectively as a surgeon, with a method of immobilisation that offers practically no complications regarding skin condition [86].
• A hand therapist can treat type 1 mallet finger injuries as effectively as a surgeon [97].
• The management of uncomplicated mallet fingers by the hand therapy team achieved satisfactory results, indicating that specialist hand therapists could treat mallet finger by themselves, providing that the patients fit the inclusion criteria for non-operative treatment [17].
• Supplemental night splinting does not improve the outcome of mallet finger in terms of extensor lag, disability, or satisfaction with treatment [52].
• 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].
• Conservative therapeutic management of acute, closed mallet finger is diverse and varied, with exercises and interventions supplementary to splinting commonly utilised [82].
• Mallet deformity accounts for a minority of sporting injuries, but excellent functional outcome can be achieved with splintage and avoidance of the causative sport while splinted [36].
• Two patients with closed mallet deformities of the thumb were treated conservatively with satisfactory results [19].
• The prevailing opinion of most authors is to treat a closed mallet thumb injury nonsurgically with splinting [111].
• A retrospective study examined the outcomes of acute bony mallet injuries treated with 4 weeks of static immobilization in a splint, followed by graduated mobilization [44].
• The clinical efficacy of the proposed method of elastic taping for the treatment of mallet finger injuries remains to be tested vigorously [76].
• The study recommends a simple splint as an alternative means of treating mallet finger [23].

Operative Management¶

• Surgery is occasionally recommended for acute or chronic cases or for salvage of failed prior treatment [6].
• It is concluded that simple surgery such as Kirschner wire fixation of the DIP joint or tenodermodesis is of benefit in most patients with mallet finger who fail to be cured by simple splintage [11].
• Although 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, a significant advantage of surgical management even in those complicated cases has yet to be clearly proven [46].
• The indications for surgical treatment of bony mallet injuries include dorsal fracture fragments of more than one-third of the joint surface on the lateral radiograph or volar subluxation of the main remainder of the distal phalanx [109].
• It is a challenging surgery performed in treatment of bony mallet finger [16].
• We propose this safe and simple technique for chronic mallet fingers if deformity exceeds 30°, for patients untreated (after the second month), or when splinting has failed [13].
• The method is a suitable alternative in patients with annoying chronic mallet finger who refuse arthrodesis or further conservative treatment [45].
• The method is simple and very effective for treatment of chronic mallet deformity [50].
• This method seems to be a new reliable alternative in the treatment of chronic mallet finger [55].
• Scar overlapping suture for treating chronic tendinous mallet finger in children is safe and effective [89].

Complications¶

• The complication rate after operative treatment of mallet fracture was 41% [117].
• The high complication rate after operative treatment of mallet fracture is likely attributable to anatomical factors such as thin extensor tendon and poor blood supply [117].
• Delayed surgical management of bony mallet fingers demonstrated minimal complications when compared with prior literature [4].
• Complication rates were low in large-fragment mallet finger cases managed conservatively [5].
• Conservative management of tendinous mallet finger injuries neglected for 2 to 4 weeks is associated with low long-term complication rates [38].
• A series of acute combined tendon and bone mallet fingers treated with pullout wire fixation and Kirschner wire stabilization reported no complications such as infection, nonunion, or nail deformity [59].

Recovery¶

Non-Operative Management¶

• Treatment by splintage produces a cure or improvement in half the patients studied [9].
• Most authorities splint only the distal joint for mallet finger deformities [10].
• The management of uncomplicated mallet fingers by a hand therapy team achieved satisfactory results, indicating that specialist hand therapists could treat mallet finger by themselves provided patients fit inclusion criteria for non-operative treatment [17].
• 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 [38].
• Nonsurgical treatment is supported for closed and displaced mallet finger fractures with greater than one-third articular surface involvement [39].
• Large-fragment mallet finger cases can be effectively managed conservatively with low complication rates [5].

Operative Management¶

• The chronic mallet deformity was corrected in each of the 12 cases reported in a series using oblique retinacular ligament reconstruction [25].
• Tenodermodesis is a useful surgical procedure in cases of mallet fingers where conservative treatment has failed [49].
• Mallet finger injuries are frequent in football and difficult to treat during the competitive season, often requiring delayed treatment or internal splinting [43].
