Review Case Reports
Simultaneous dislocation of both joints of the thumb with a fracture involving the interphalangeal joint. A case report and a review of the literature.
Combined dislocation of the metacarpophalangeal and interphalangeal joints of the thumb is uncommon, only five cases having been previously reported. In this case report, a previously unreported case characterized by volar-ulnar dislocation of the metacarpophalangeal joint and dorsal dislocation of the interphalangeal joint, associated with a unicondilar open fracture of the proximal phalanx, is presented. ⋯ Although the diagnosis of dislocation of the interphalangeal joint is obvious, a simultaneous dislocation of the metacarpophalangeal joint can be easily overlooked, which is a fact that underlines the importance of this article. It is therefore recommended to examine the whole hand.
