Abstract

Recurrent motor branch entrapment syndrome is a compressive mononeuropathy of recurrent motor branch of median nerve. It is a rare condition as a cause of thenar muscle wasting and may have different pathogenesis. If such an anatomical variation is the cause, there is a possibility that thenar muscle atrophy remains if only the transcarpal ligament release is performed. We report a 25-year-old male patient with carpal tunnel syndrome with thenar muscle wasting 1 month ago.

Key Words: Carpal tunnel syndrome, Median nerve, Recurrent motor branch
