Transfer of the radial branch of the superficial radial nerve to the sensory branch of the ulnar nerve for sensory restoration after C7-T1 brachial plexus injury.

Previously, we have reconstructed the motor function of patients with C7-T1 brachial plexus palsies through combined nerve and tendon transfers. However, these patients lose not only the motor function of the hand but also the sensation on the ulnar side of the hand. Without sensory recovery, the injured hand may be further damaged, particularly by burns in this contact zone. Therefore, we described a technique to restore the sensation at the ulnar aspect of the hand by performing a transfer of the radial branch of the superficial radial nerve to the sensory branch of the ulnar nerve.
