Radial nerve injuries, at different levels, have been reported in swimming, tennis, golf, weight lifting, and several kinds of throwing sports. The mechanisms of injury include direct trauma and compression injuries. Radial tunnel syndrome is an uncommon pathology. However 5–8% of patients with chronic lateral epicondylitis have involvement of the posterior interosseous nerve (Celli et al. Treatment of elbow lesions. Spinger 281–297, 2008).

It is important to differentiate the two clinical syndromes related to the radial nerve.

The radial tunnel syndrome (RTS) is a compression of the radial nerve in a potential space four fingerbreadths long, located along the anterior aspect of the proximal radius, whereas the posterior interosseous nerve (PIN) syndrome relates to a compression of the PIN, with weakness of its muscles. There is weakness of extension of all of the digits, with sparing of the extensor carpi radialis brevis (ECRB).

The proximal radial nerve compression sites include fibrous bands between brachial and brachioradialis muscle anterior to the radiocapitellar joint, recurrent radial vessels (leash of Henry) at the radial neck, bands at the medial proximal edge of ECRB muscle or at the Frohse arcade (proximal edge of the superficial portion of the supinator muscle), as well as at the distal edge of the supinator muscle. The most common site includes membranous or tendinous fibers of the proximal edge of the supinator muscle. Surgery indicated if clinical symptoms of radial nerve entrapment despite conservative treatment persist.
