Abstract

Mallet finger in adults is a traumatic lesion of the terminal extensor band in zone 1, and is characterized by intact skin and division of the tendon insertion alone (tendinous mallet) or an avulsion of less than one third of the articular surface of the distal phalanx (bony mallet) resulting in inability to actively extend the distal interphalangeal joint. When untreated, this can lead to osteoarthritis at the distal interphalangeal joint and, potentially, a swan-neck deformity. Although a wide variety of both open and percutaneous surgical techniques have been described for the treatment of mallet fractures, accurate anatomic reduction and stable fixation of mallet fractures remains one of the most challenging operations in hand surgery. Common problems with existing pin, wire or screw techniques include loss of reduction, recurrent subluxation, pin migration, wire cut-out and the common requirement for prolonged trans-articular K-wire splintage and consequent inability to initiate early motion of the distal interphalangeal joint.
