title: Boutonniere deformity of the second toe after planter dislocation of proximal interphalangeal joint: a case report.
abstract: The boutonniere deformity is a well-known deformity in the fingers, however, its appearance on a lessor toe is extremely rare. In the present case, the deformity resulted from a rupture of the central slip of the extensor tendon and the shift of the lateral bands to the planter side after reduction of a traumatic planter dislocation of the PIP joint of the second toe. Surgical repair of the extensor mechanism brought good results.
