Abstract

Guyon syndrome is the well-known ulnar entrapment at the wrist; usually surgical decompression improves the symptoms. Neurophysiological studies are essential to demonstrate the abnormality of ulnar nerve conduction at the wrist. We report a case of Guyon syndrome onset after 6 h of cycling. Neurophysiological study revealed ulnar neuroapraxic block at the wrist, and axonal impairment. Post-operative clinical and neurophysiological follow-up showed marked clinical improvement and neurophysiological resolution of abnormalities. To our knowledge, no cases of Guyon syndrome with neuroapraxic block are reported in the literature. Copyright (C) 1998 Elsevier Science Ireland Ltd.
