Stener lesion after lateral dislocation of the proximal interphalangeal joint--indication for open reduction.

The management of lateral dislocations of the proximal interphalangeal joint is controversial. Absolute indications for operative management are few, and most dislocations can be treated nonoperatively. In this case, the ulnar collateral ligament was trapped between the lateral hand and central slip of the dorsal apparatus and required open reduction for a satisfactory functional result.
