Abstract
This article describes the use of a miniplate and cortical screws in the treatment of five cases of flexor digitorum profundus (FDP) tendon avulsion. One case was type II, three cases were type III and one case was type IV. Near normal joint congruity was restored together with bony union in all cases. Six months after surgery four cases had near normal range of motion at the distal interphalangeal joint compared with the contralateral uninjured finger. These four patients were to return to their previous activities without restriction by 3 months. One repair of a type III avulsion ruptured but the distal interphalangeal joint was pain free and stable and the patient declined further surgery. Miniplate fixation offers some advantages over existing methods of repair and adds to the range of techniques available for reattachment of the FDP tendon in these injuries.
