Paralysis of the ulnar nerve in cyclists.

Paralysis of the ulnar nerve in cyclists was first documented ninety years ago. Increase in the number of cyclists has revived interest in this pathology which occurs apparently only amateurs. The authors report three cases to add to the thirty-five previously reported cases of the literature. The onset of symptoms and their specific features are dealt with and the advantage of electromyography is emphasized. Evolution is spontaneously favorable in almost all cases. Cycling can be resumed with certain precautions once symptoms have completely subsided.
