Surgical exposure of the Distal Radius in a patient with a flexor carpi radialis brevis muscle anomaly

Abstract

There are numerous reports of anatomical variants of the muscles of the forearm, particularly the extensors of the wrist and hand. The abnormal deep and short radial wrist flexor (flexor carpi radialis) is rare. There are only two previously reported cases. We present the case of an anomalous ‘flexor carpi radialis brevis’, muscle found intra-operatively during a volar approach to the distal radius and discuss the strategies needed for further exposure in order to complete the procedure.
