The initial results of using radiofrequency probes for debridement of a torn triangular fibrocartilage complex were studied in 20 patients with a mean age of 44 (range 27-56) years presenting with ulnar-sided wrist pain. On arthroscopic examination, 18 central and two radial triangular fibrocartilage complex tears were identified and debrided to a stable rim using radiofrequency probes. The mean follow-up was 22 (range 9-35) months. Seventeen patients experienced substantial pain relief. In three, the pain was unchanged. The mean flexion extension arc was 132 degrees , pronosupination arc 155 degrees and mean grip strength was 83% of that of the unaffected side. Using the modified Mayo wrist score, there were ten excellent, seven good and three fair results. No perioperative complications occurred. Radiofrequency probes were found to be safe and effective for use in triangular fibrocartilage complex debridement. These results compare favourably with other standard methods of treatment of this problem.
