ABSTRACT

Ligament reconstruction and tendon interposition (LRTI) procedures for trapeziometacarpal osteoarthritis aim to prevent proximal metacarpal migration to improve thumb function. We sought to evaluate the effect of the remaining trapezial space on outcomes after trapeziectomy with LRTI. Forty-seven patients were included in this study. Patients were evaluated clinically and radiologically. They were divided into two groups according to the remaining trapezial space at last follow-up. Postoperative to preoperative trapezial space ratio was >50% in group 1 and <50% in group 2. Mean follow-up was 30.8 months. Mean age, sex, dominant side, preoperative stage, and follow-up were similar in both groups. The mean QuickDASH scores were significantly better in group 1 than group 2. Mean tip and key pinch were significantly stronger in group 1, than group 2. Trapeziectomy with LRTI is the most used surgical technique and it produces satisfactory results. Improved clinical outcomes can be achieved when more than 50% of the preoperative trapezial space remains.
