Treatment of Palmer Class 1A Triangular Fibrocartilage Complex Injuries with Arthroscopic Partial Resection

ABSTRACT

PURPOSE: We reported the clinical results of Palmer class 1A triangular fibrocartilage complex (TFCC) injuries treated with arthroscopic partial resection. METHODS: This study included eighteen patients with Palmer class 1A TFCC injury. The results of arthroscopic partial resection were analyzed based on the preoperative and postoperative evaluation of visual analogue scale pain scale, range of motion, grip strength, Mayo wrist score, ulna grind test, ulna stress test and ulnocarpal tenderness. RESULTS: According to the Mayo wrist score, the results were excellent in 10 patients, good in 4, fair in 2, and poor in 2. There was no correlation among the worker's compensation, interval from injury to surgery, age and the treatment results. Patients with complication and scapholunate interosseous ligament tears had a poor clinical outcome. CONCLUSION: The arthroscopic TFCC partial resection is considered as an useful and effective treatment in Palmer class 1A TFCC injuries.
