The ulnar nerve is decompressed in the wrist through Guyon’s canal and in the hand, specifically the deep motor branch of the ulnar nerve. This deep motor branch is released by dividing the tendious arch of the hypothenar muscles. In addition, a carpal tunnel release is performed by transecting the transverse carpal ligament.
