Superficial Branch of the Radial Nerve
The Superficial Branch of the Radial nerve descends in front of the lateral epicondyle of the humerus. The superficial branch of the radial nerve lies deep to the brachioradials muscle. In the distal portion of the forearm, the superficial radial nerve leaves the protection of the brachioradialis and winds around the the lateral surface of the radius. On the extensor surface of the wrist, the superficial branch of the radial nerve divides into dorsal digital nerves for the radial two and a half digits as far distal as the proximal interphalangeal joints.
