The Repair of the Intra-Articular Bony Avulsion of the Flexor Digitorum Profundus Tendon (Report of Four Cases

Four patients with the intra-articular bony avulsion of the deep finger flexor (FDP) were treated by open reduction and internal fixation with mini screw. They were examined for the tendon function and range of motion of the distal interphalangeal (DIP) joint. The follow-up period was from 6 months to 60 months. DIP joint surface was involved in all the cases. Although the FDP function was restored there was reduced range of motion in DIP joints in all the patients. Beside the restoration of FDP function the condition of the DIP joint surface is another important factor which influences the prognosis and the treatment of FDP avulsion injuries
