title: Hemiresection-interposition arthroplasty of the distal radioulnar joint associated with repair of triangular fibrocartilage complex lesions.
abstract: Sixteen wrists of 15 patients with traumatic triangular fibrocartilage complex tears were treated by hemiresection-interposition arthroplasty of the distal radioulnar joint combined with repair of the torn triangular fibrocartilage complex. The surgical procedure was performed to avoid impingement of the ulnar head against the reconstructed triangular fibrocartilage complex. Most of the wrists showed a positive ulnar variance. The average age of the patients was 39 years. Follow-up averaged 41 months. Complete relief of pain was obtained in 10 wrists. Slight pain persisted in 6 wrists, although it was less than before surgery. The range of motion of the wrist joint and forearm improved postoperatively. Grip strength in all wrists increased. Postoperative complications occurred in 7 wrists of 6 patients: reoperation in 2 wrists, fracture in 1, and tendinitis of the extensor carpi ulnaris in 4. All 15 patients subsequently returned to their previous occupations.
