Submuscular Ulnar Nerve Transposition 3 Mackinnon SE1 Yee A1 March 8, 2011Disclosure: No authors have a financial interest in any of the products, devices, or drugs mentioned in this production or publication.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.Keywords: ulnar nerve transpositioncubital tunnel syndrometransmuscular transpositioncompression neuropathyulnar nervenerve decompression You must login to view the full article and extended video on this page.
