Peripheral Radial Nerve Injury

Upon deriving its nerve supply from the C5, C6, C7, C8, and T1 levels, the radial nerve spirals about the humerus (Gardner & Bunge, 1984, pp. 23-24). The proximal nerve innervates the brachioradialis, as well as both the flexor carpi radialis longus and brevis, to cause forearm flexor and wrist extension (Sloan, 1993, p. 654). Descending laterally through the spiral groove, the radial nerve penetrates the lateral intermuscular septum, descends behind the brachioradialis and brachialis muscles, and-- at the antecubital space--divides into the posterior interosseous and superficial radial branches (Stroyan & Wilk, 1993, p. 284). Compressive neuropathy refers to nerve injury due to acute or chronic repetitive external pressure. Neuropathy tends to affect the radial nerve less frequently than the median or ulnar nerves. Radial nerve compression has a wide range of presentations. There are five different syndromes associated with radial deficits: three involve the radial nerve itself; whereas two occur in its

r tendinous arcade of Frohse has been reported in 80% of patients who undergo surgical release for compressive radial symptoms; its incidence in cadavers is from 20-30%. Two other anatomic areas with the potential to impair radial nerve function include the extensor carpi radialis brevis muscle and the leash of Henry. The extensor carpi radialis brevis muscle has a sharp border which overlies the posterior interosseous nerve. The leash of Henry consists of the vascular arcade, including the muscular branches off the radial artery and the recurrent radial artery (Eaton & Lister, 1992, p. 350). Moreover, certain abnormal structures have been correlated with specific compressive radial nerve syndromes. For example, posterior interosseous syndrome commonly occurs in patients with space occupying lesions at the elbow. In contrast, radial tunnel syndrome is strongly associated with a fibrous arcade of Frohse. A comprehensive explanation for these observed differences remains lacking. Radial nerve compression produces a variety of symptoms. In the proximal forearm, the clinical findings may resemble the pronator and anterior interosseus syndromes of median nerve compression. The two syndromes, posterior interosseous and radi
