Disability of the hand and wrist occurs quite frequently after injury to the wrist. Although several causes have been listed in the literature, lack of return to normal function because of tendovaginitis involving the fifth dorsal compartment of the wrist has not been generally recognized and rarely has been reported in the literature.
