A Pragmatic and Evidence-Based Approach to Mallet Finger

Abstract

A mallet finger is a common injury that results from a sudden flexion force on an extended distal phalanx or rarely, from hyperextension of the distal interphalangeal joint. Mallet finger can be purely tendinous or bony when associated with an avulsion fracture. The management of this injury is largely conservative with the use of a splint, although surgery may be indicated for select patients. There is little consensus on the indications for surgery or the suitable surgical technique. The aim of this review article is to provide a pragmatic and evidence-based approach to mallet finger that will guide the treating surgeon in providing best care for their patient.
