Radial nerve compression.
Symptomatic radial nerve compression is relatively uncommon. A relatively high incidence of compressive neuropathy involves other major nerves in the same extremity. Because sensory complaints are minor, radial nerve compression may successfully masquerade as tendonitis or tendon rupture. The most common site of radial nerve compression is in the forearm, at the arcade of Frohse. Spontaneous onset of dense paralysis is often due to space-occupying lesions in the forearm. Trauma-related compression in the forearm is most often due to radial head dislocation and either humeral fracture or local external pressure in the upper arm. Compression resulting in weakness that does not improve with several months of splinting, anti-inflammatory medication, and activity changes should be treated surgically to reduce the extent of permanent deficit. After decompression, early active motion is instituted to encourage nerve gliding. Results after decompression are not as favorable as those for carpal or cubital tunnel release. The worst results of decompression are seen in patients who have work-related injuries, chronic pain, and poor localization of symptoms on physical examination.
