[Results of arthroscopic repair of triangular fibrocartilage complex peripheral tears (Palmer type 1B)].

BACKGROUND

Triangular fibrocartilage complex (TFCC) injury is the major cause of wrist pain on the ulnar side. In this study, treatment outcomes of arthroscopically repaired peripheral TFCC tears (Palmer type 1B) were evaluated retrospectively.

METHODS

Thirty-eight patients (30 males, 8 females; mean age 27.6; range 19 to 42 years) with TFCC tears (Palmer type 1B) who were treated arthroscopically between February 2007-July 2012 were evaluated retrospectively. The data were collected by Mayo wrist evaluation form and by preoperative and postoperative visual analogue scale (VAS).

RESULTS

The results of the data collected by the Mayo wrist evaluation forms were perfect in 30 patients and good in 8 patients. Preoperative VAS was 6.53 (range: 4.5-8.2) and postoperative VAS was 1.48 (range: 0.3-3.1).

DISCUSSION: With the arthroscopic technique, TFCC tears can be repaired with minimal harm and better visualization, and evaluation of all the structures of the wrist can be done. Outside-to-inside suturing technique, which is performed through the portal opened 1 cm inferior to the 6R portal, is the least traumatic technique and does not carry the risk of injury to the superficial branch of the ulnar nerve. With this technique, the complaints of preoperative pain can be eliminated significantly.
