Hyperextension mallet finger.

Mallet finger injury of the distal extensor mechanism of a digit represents a spectrum of pathology. The hyperextension variant, characterized by a major intraarticular fracture fragment and volar subluxation of the distal phalanx, requires specific recognition. Its distinctive mechanism of injury requires modification of routine mallet finger management, whether open or closed. Persistent volar subluxation, in our experience, has been associated with consistently unsatisfactory results. Copyright 2013, SLACK Incorporated.
