Proximal median neuropathy secondary to humeral neck fracture.

Median neuropathies proximal to the wrist are uncommon and usually result from penetrating injuries, fracture dislocation of the distal humerus, or compression by fibrous bands. A 66-year-old man suffered a comminuted fracture of the proximal humerus after a fall. Electrodiagnostic studies revealed a severe proximal median neuropathy and a mild distal radial mononeuropathy. Proximal median neuropathy rarely occurs in humeral neck fracture, mostly because the median nerve is not in close contact with the humerus proximally. Copyright 2000 John Wiley & Sons, Inc.
