PURPOSE: To present the early results of arthroscopic debridement and thermal shrinkage using radiofrequency probes for partial (Geissler grades I and II) scapholunate (SL) interosseous ligament injuries of the wrist.
METHODS: Sixteen patients with a mean age of 34 years (range, 18-54 y) presenting with chronic dorsoradial wrist pain unresponsive to initial conservative treatment for a mean period of 12 weeks were included in this study. No patient showed radiologic signs of static dissociation (SL interval, <3.5 mm; mean SL angle, 49 degrees ) before surgery. Diagnostic arthroscopy showed a partial SL tear in 14 patients and redundancy of the ligament in 2. Partial SL tears involved the membranous (proximal) and volar part of the ligament. All lesions were debrided and treated with thermal shrinkage using a bipolar radiofrequency probe.
RESULTS: The mean follow-up period was 19 months (range, 9-34 mo). Fourteen patients experienced substantial pain relief whereas in 2 the pain remained unchanged. Eight patients were completely pain free. The mean flexion-extension arc was 142 degrees and the mean grip strength was 78% that of the unaffected side. No patient showed radiologic signs of arthritis or static or dynamic instability after surgery (SL interval remained <3.5 mm; mean SL angle, 53 degrees ). Based on the modified Mayo wrist score there were 8 excellent, 6 good, 1 fair, and 1 poor result.
CONCLUSIONS: Partial SL ligament tears can be a source of radial-sided wrist pain. Scapholunate ligament debridement and thermal shrinkage effectively provided pain relief for most of the patients treated. Stability was maintained radiographically. No complications were noted from the use of radiofrequency probes. These reasonably favorable short-term results should be viewed cautiously. A longer follow-up study is necessary to determine the ultimate efficacy of this procedure.
