PITFALLS IN CARPAL TUNNEL DECOMPRESSION

Abstract

In the period 1972 to 1977, 35 patients with persistent pain and other disabilities after carpal tunnel decompression were referred for treatment. The pitfalls included: (i) wrong diagnosis--5 patients; (ii) inadequate decompression--9 patients; (iii) recurrent compression--4 patients; (iv) iatrogenic nerve injury--7 patients; and (v) postoperative complications--10 patients. The patients in Groups 1 and 5 were treated by non-operative measures. Most of the patients in Groups 2, 3, and 4 were treated by reoperation. This paper outlines the causes and prevention of pitfalls in carpal tunnel decompression.
