title: [Mallet-thumb--presentation and discussion of 3 cases of a rare lesion].
abstract: Three cases of closed extensor tendon ruptures without osseous involvement in Verdan's zone 1 of the thumb (Mallet thumb) are presented and the various treatment options discussed based on the pertinent literature. As a consequence of the special anatomy of the thumb's extensor tendons which differs from that in the fingers, we recommend surgical treatment of this rare lesion by transosseous refixation of the ruptured tendon. Thus, early postoperative motion can be initiated resulting in rapid recovery of complete function.
