[A rare anomaly of the superficial flexor tendons of the little finger]

Abstract

A rare anomaly was found in both hands of an eighty-five-year old female. The muscle bellies of the superficial finger flexor muscle for the little finger were absent. Instead of this, a thin tendinous cord arose from the tendon of the flexor superficialis of the ring finger proximal to the carpal tunnel to pass into the radial side of the flexor tendon sheath of the little finger at the level of the annular ligament A 1. Together with an abortive tendon on the ulnar side the tendon inserted into the middle phalanx. The flexor digitorum profundus muscle of the little finger was normal.
