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).
近端指间关节（PIP）损伤在运动员中很常见，尤其是在对抗性和球类运动中（1）。大多数PIP损伤涉及掌板断裂或背侧脱位。较少见的是“纽扣指”损伤，如果未被诊断和治疗，会导致纽扣指畸形。这种畸形难以处理，通常需要长期固定和/或手术来恢复功能（2）。
