Abstract:

A case report describing the very rare finding of bilateral Anconeus Epitrochliaris. The patient presented with bilateral ulnar nerve symptoms and intraoperative findings identified bilateral Anconeus Epitrochliaris as the cause to the ulnar nerve compression. Ulnar nerve compression can occur at various sites within the cubital tunnel, with the most common sites being the 2 heads of the Flexor Carpi Ulnaris muscle, arcade of struthers and between Osborne’s Ligament and the MCL. Entrapment by the Anconeus Epitrochliaris muscle is a rare finding and is present in approximately 3%-34% of individuals. Furthermore, those found to have this muscle have a 25% chance of having bilateral muscles thus ulnar nerve entrapment is likely in the opposite arm. Careful history and examination is key in diagnosing and treating ulnar nerve entrapment regardless of the cause.
