Abstract
The boutonniere (French for button hole) deformity is a result of an injury to the finger extensor mechanism that causes a characteristic flexion attitude of the proximal interphalangeal joint and distal interphalangeal joint hyperextension. This article reviews the pertinent anatomy, the mechanisms of injury, the diagnosis, and a systematic approach to the prevention and treatment of the boutonniere deformity.
