ABSTRACT:
An improved method and instrument design for performing endoscopic transverse carpal ligament release surgery. The improved instrument design comprises a working end, such as a knife blade, a rasp, a curette or a blunt right angle probe, connected to a handle. The handle is positioned at an angle of approximately 21 degrees relative to the working end. The improved method eliminates the step of retracting the flexor tendons and/or ulnar nerve at any time during the surgery. Furthermore, the design of two knife blades is described that allows the number of cutting steps involved in the surgery to be reduced from five to three.
