This video shows the release of the carpal tunnel using a two portal technique. Once the cannula is introduced the camera is brought in through the palmar incision. The camera looks up at the undersurface of the transverse flexor retinaculum. A cotton tip is used to clear the cannula then a probe is used to check the ligament prior to cutting it. Next the special knife is introduced and used to cut the flexor retinaculum completely. As the ligament is cut it tends to spring apart and fat bulges through the cut ends into the cannula. At the end of the operation the cut ends of the ligament and the median nerve can be inspected by rotating the cannula and the camera. the two incisions are then closed with a buried subcuticular stitch.
