Distal Interphalangeal Joint Fractures of the Hand.

Abstract

Fingertip fractures are some of the most common traumas encountered by hand surgeons. The distal interphalangeal joint is frequently involved and encompasses a spectrum of injury that can require simple splinting to open reduction and internal fixation procedures. Fractures can be classified into those that involve mainly dorsal or mainly volar articular fragments versus those that involve a combination of the two with comminution. Fractures can be either closed or open, associated with joint instability and/or involve inserting tendon disruption. Anatomic reduction of the articular surface is desirable but often not necessary to achieve a good outcome. Optimal outcome is governed by a timely diagnosis with initiation of appropriate treatment, restoration of tendon insertion integrity (when applicable), and improvement of joint concentricity.
