A submuscular ulnar nerve transposition is performed to decompress the ulnar nerve in the cubital tunnel at the elbow. The medial antebrachial cutaneous nerve is identified and protected. Proximally, the medial intermuscular septum is resected. A step-lengthening of the fascia of the flexor-pronator muscles is performed. The ulnar nerve is placed in a transmuscular location. More importantly, the distal fascial septum between the flexor carpi ulnaris and the flexor-pronator muscles is removed.

POSITION
Supine.
INCISION
Incision is placed behind the medial epicondyle along the course of the nerve. The dotted line denotes the course of the medial antebrachial cutaneous branch across the incision and is found approximately 3.5cm distal to the medial epicondyle.
