The variable clinical manifestations of ulnar neuropathies at the elbow

Abstract

In twenty-five cases of ulnar neuropathy at the elbow, the involvement of the fibres from three sensory and to four motor branches were examined clinically and, where possible, electrophysiologically. Of the sensory fibres, those from the terminal digital nerves were most commonly involved. The fibres to the hand muscles were much more frequently involved than those to the forearm muscles. These findings suggest that in ulnar neuropathies at the elbow there is variable damage to the fascicles within the nerve.
