Carpal tunnel syndrome caused by the palmaris profundus muscle. Case report
1Department of General Surgery, County Hospital, Köping, Sweden.
Abstract:
The palmaris profundus muscle is a rare structure that originates from the radial portions of the forearm. Its discrete tendon passes through the carpal tunnel, attaching distally to the palmar aponeurosis. If it interferes with the median nerve it may cause carpal tunnel syndrome. The finding can be compared with similar observations in comparative anatomy.
