Abstract
OBJECTIVE: The purpose of this pilot study was to evaluate the feasibility of joint distraction of the first carpometacarpal (CMC1) joint in patients with CMC1 osteoarthritis (OA). METHODS: An external joint distractor was placed over the CMC1 joint by K-wire fixation in the trapezium and the metacarpal. The joint was distracted 3 mm during surgery. The device was then kept in place for 8 weeks. Disabilities of the Arm, Shoulder, and Hand (DASH) score, Michigan Hand Outcome Questionnaire (MHQ), Visual Analogue Scale (VAS), and grip strength were recorded preoperatively and at set postoperative intervals. RESULTS: Five female patients with an average age of 53 years (range = 41-61) were included. One year postoperatively, average DASH, MHQ, and VAS scores improved compared to preoperative values; DASH 53 to 27, MHQ 48 to 76, and VAS pain 48 to 14. There were no technical problems associated with the device. One patient had a local pin site infection treated successfully with oral antibiotics. CONCLUSIONS: This study concludes that joint distraction of the osteoarthritic CMC1 joint is technically feasible. In this small, prospective pilot study the majority of the results were favourable during short-term follow-up.
