Arthroscopic Repair for Traumatic Peripheral Tear of Triangular Fibrocartilage Complex

ABSTRACT

PURPOSE: To assess the results of an arthroscopic repair for traumatic peripheral tears of triangular fibrocartilage complex (TFCC, Palmer type Ib). MATERIALS AND METHODS: 10 patients with traumatic peripheral TFCC tear were treated with outside-in technique with arthroscope and evaluated with an average follow-up of 19 months (range, 15 to 28 months). The clinical outcomes were assessed with investigation of pain, range of motion, grip strength, return to job and patient's satisfaction. RESULTS: The arthroscopic repair of traumatic peripheral TFCC tear resulted in significant pain relief and increase in functional ability of wrist, that is, 8 excellent, 1 good and 1 fair results. At last follow-up, the average of flexion was 79° (range 76~86°), average of extension was 78° (range 70~84°), average pronation was 85° (range 75~91°) and average supination was 87° (range 79~92°). Nine patients except one were back to their original job. CONCLUSION: Arthroscopic repair of traumatic peripheral TFCC tear could be used for pain relief and increase in functional ability of wrist.
