Abstract:
PURPOSE: The purpose of this study was to analyze the clinical results of patients with scaphoid nonunions treated with arthroscopically assisted bone grafting and percutaneous K-wires fixation. METHODS: We retrospectively reviewed 20 patients with a scaphoid nonunions which was treated with arthroscopically assisted bone grafting and percutaneous K-wires fixation from November 2008 to July 2012. Time from injury to treatment was 74 months (range, 3-480 months) in average. Functional outcome was evaluated using the modified Mayo wrist score and visual analogue scale (VAS) for pain, which were measured before operation and at the last follow up. RESULTS: All nonunions were healed successfully. The average radiologic union time was 9.7 weeks (range, 7-14 weeks). The average VAS score improved from 6.3 (range, 4-8) preoperatively to 1.6 (range, 0-3) at the last follow up. The average modified Mayo wrist score increased from 62.5 preoperatively to 85.7 at the last follow-up. CONCLUSION: Arthroscopically assisted bone grafting and percutaneous K-wires fixation is an effective treatment method for a scaphoid nonunion. It may provide more biological environment than open surgery as a minimally invasive procedure.
