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.

This 33 year-old female patient suffered from right wrist pain due to slip down.
(A) The wrist AP radiograph shows the old fracture of distal radius and non-union of ulnar styloid process.
(B) T2 weighted coronal MR image shows the peripheral tear of TFCC (arrow).
(C) Palmer type 1b TFCC tear was obvious on the arthroscopic field after shaving the hypertrophied synovium.
(D) Outside-in technique. The curved spinal needle was inserted through the ulnar capsule and triangular fibrocartilage. Then 2-0 PDS was inserted through this spinal needle.

(F) 2-0 PDS was remained inside the loop which was inserted into the joint cavity through the straight spinal needle.

(H) The triangular fibrocartilage was tied to the capsule of ulnar side.
