Wartenberg's syndrome, or compression of the sensory branch of the radial nerve, occurs in the interval between the brachioradialis and the extensor carpi radialis longus approximately 8 cm proximal to the radial styloid. There may be history of repetitive wrist/forearm circumduction activity (ie, knitting) or of wearing a tight wristwatch or jewelry. It can occur in patients who have been handcuffed. Typical clinical findings are pain, paresthesia, and/or hypesthesia in the dorsoradial aspect of the wrist and hand in the distribution of the radial sensory nerve. There is often a positive Tinel's sign over the compression site. Hypesthesia may be present in the distribution of the radial sensory nerve which is typically on the dorsal aspect of the first dorsal web space and dorsum of the thumb; however, with overlap in the distribution of the superficial radial nerve and the lateral cutaneous nerve of the forearm this may not always be present. Surgical management consists of release of the nerve as it exits the interval between the brachioradialis and the extensor carpi radialis longus in the distal forearm.
