Ulnar Nerve Injury and Entrapment
The ulnar nerve originates from the medial cord of the brachial plexus (C8, Th1), runs down along the ulnar side of the arm, and comes out to the flexor-ulnar side of forearm after passing through the sulcus nervi ulnaris at the medial epicondyle of the humerus. It further runs down to the ulnar side of forearm and reaches the palm thorough the Guyon canal (Fig. 1).
