[Muscular malformation of the wrist in an initial carpal tunnel syndrome. Clinical case].
A carpal canal syndrome in a young female subject was found at the operating table to be due to a wrist muscle abnormality. An extra muscle leaving the styloid process of the radius in the direction of the transverse ligament of the carpus, and an abnormal distal development of the muscular belly of the superficial flexor of the third finger, had led to compression on the median nerve corresponding to the carpal canal. Check on motor and sensitive conduction of the median nerve revealed nerve damage at wrist level. Removal of the extra muscle and section of the transverse ligament of the carpus resolved the painful symptomatology. Control of nervous conduction two months after operation confirmed the improvement.
