Transverse bayonet dislocation of the distal interphalangeal joint--a case report.

Transverse bayonet dislocation of an interphalangeal joint is an unstable injury caused by the disruption of both collateral ligaments. This injury pattern in proximal interphalangeal joint was first described by Patel et al. (Clin Orthop Rel Res. 1978;133:219), who coined the term "bayonet dislocation" to describe this particular type of injury. The case of a distal interphalangeal transverse dislocation is presented. This dislocation was successfully treated by closed reduction and immobilization with an aluminum splint and buddy taping to the adjacent finger.
