Figure 5.

Schematic representation of procedures to restore sensation on the ulnar side of the hand in patients with a lower-type palsy of the brachial plexus. Either the palmar cutaneous branch of the median nerve was transferred to the dorsal branch of the ulnar nerve, or the proper digital nerve of the little finger was sutured to fascicles of the median nerve to the palm, either in association or not in association with fascicles raised from the proper ulnar digital nerve of the index finger.
