Transmuscular Ulnar Nerve Transposition in a Case of Traumatic Medial Cord Injury

Cubital tunnel syndrome can present with pain/numbness in the ulnar nerve territory and weakness in the ulnar-innervated extrinsic/intrinsic muscles. The etiology for cubital tunnel syndrome depends on the case and includes various points of compression along the course of the ulnar nerve. The most common compression point is the medial epicondyle at which the fascial […]

Submuscular Ulnar Nerve Transposition

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. […]
