Quick splint for acute boutonniére injuries.

Injuries to the proximal interphalangeal (PIP) joint are common in athletes, especially in contact and ball sports(1). Most PIP injuries involve disruption of the volar plate or dorsal dislocation. Less common is the "boutonniére" injury, which, if left undiagnosed and untreated, results in a boutonniére deformity. This deformity is difficult to manage and often requires prolonged immobilization and/or surgery to regain function(2).
