Position Change of the Neurovascular Structures around the Carpal Tunnel with Dynamic Wrist Motion.

It is appropriate to transect the ligament greater than 4 mm apart from the lateral margin of the hook of the hamate without placing the edge of the scalpel toward the ulnar side. We would also recommend not transecting the transverse carpal ligament in the ulnar flexed wrist position to protect the ulnar neurovascular structure. Kwon JY, Kim JY, Hong JT, Sung JH, Son BC, Lee SW. J Korean Neurosurg Soc. 2011 Oct;50(4):377-80.
