Trapeziometacarpal joint osteoarthritis and carpal tunnel syndrome: a new surgical approach for concomitant treatment

A new approach for the concomitant surgical treatment of trapeziometacarpal joint osteoarthritis and carpal tunnel syndrome through the same incision is described. The technique was used in 25 patients (20 women, five men; mean age, 56 years). At a mean follow-up of 27 months, there was complete disappearance of the symptoms of carpal tunnel syndrome in 20 of the 25 patients, incomplete but substantial relief in four patients, and no improvement in one patient. One patient had scar tenderness and another had a superficial wound infection. The surgical technique is simple, safe and cost-effective as it avoids separate operations for both pathologies. The procedure is not suitable for severe carpal tunnel syndrome or when direct visualization of the median nerve and the carpal tunnel is necessary.
