Complications of endoscopic carpal tunnel release.

Carpal tunnel release has a high rate of success when the open or endoscopic technique is used. The reported complications of the endoscopic procedure have included incomplete release of the transverse carpal ligament and injury to the neurovascular structures or flexor tendons. The complication rates are comparable when performed by surgeons well versed in the technique. The procedure is technically demanding but can be performed safely with an understanding of the anatomic structures at risk and strict adherence to surgical methods. The technique has a steep learning curve and requires considerable practice on cadaveric specimens after attendance at one of the available courses.
