Abstract: This study presents the cases of Eaton and Littler's ligament reconstruction for the treatment of instability of lst CM joint resulting from early stage osteoarthritis (Group OA), trauma (Group T), and a part of generalized joint laxity (Group GJL) in 21 joints of 20 cases. Omitting six cases with less than one year follow-up, 15 joints in 14 cases were analyzed. Clinically, hypermobility pain was improved in all joints. However, eight out of 14 patients felt their joints stretched, but still had the normal range of motion. Grip power and pinch power was significantly improved (P<0.01, P<0.05). Comparing each group, only Group T revealed a significant difference between preoperative and postoper- ative grip power (P<0.01). In increase of grip power, Group T were more significantly improved than Group OA (P<0.01) and Group GJL (P<0.05). Radiographically, postoper- ative stages of 4 joints in 4 cases out of 8 cases which felt stretched progressed from their preoperative stages. We assumed that the newly reconstructed ligament may be strong enough to maintain the stability of 1st CM joint and ligament reconstruction is most effective in treating post-traumatic instability.
