Flexor tendon anomalies in a patient with carpal tunnel syndrome.

A case of an anomalous interconnection between the tendons of the flexor pollicis longus and the flexor digitorum profundi to both the index and middle fingers at the wrist of a patient presenting with carpal tunnel syndrome is described. The contents of the carpal tunnel should be inspected carefully at the time of median nerve decompression in cases where preoperative clinical examination suggests associated pathologies.
