Anterior subfascial transposition of the ulnar nerve

After anterior subfascial transposition, the ulnar nerve ties superficial to the flexor-pronator muscle group but deep to its fascia. Eight patients with cubital tunnel syndrome were treated with this method and reviewed retrospectively. The average age at the time of operation was 52 years. All patients had severe cubital tunnel syndrome based on Dellon's classification. The average follow-up period was 2 years and 9 months. Post-operative outcome assessment was based on the modified Bishop rating system. Six patients had excellent and two had good outcomes. All were back at work by the 5th post-operative week. There were no complications or recurrence of symptoms. Anterior subfascial transposition of the ulnar nerve is an effective method of surgical treatment for patients with severe cubital tunnel syndrome.
