[Complications after endoscopic carpal tunnel decompression].

In an own prospective series with 18 endoscopic decompressed carpal tunnel syndrome patients the problems with this new release technique are described. Although most of the patients did clinically well, four major complications, all with revision operations, were observed. Two cases still suffer residual problems. Due to these complications we stopped the endoscopic technique and returned to the traditional surgical treatment of open carpal tunnel decompression.
