The flexor carpi radialisbrevis muscle - an anomaly in forearm musculature: a review article.

The volar approach to the distal radius is an increasingly popular method of exposing fractures of the distal radius for purposes of reduction and internal fixation. We present five clinical cases and one cadaveric case of an incidental finding of an aberrant flexor of the forearm. A literature review undertaken showed few previous case reports of this relatively uncommon anatomic variant. The possibility of seeing the flexor carpi radialis brevis muscle during a volar approach to the distal radius should be made known to all orthopedic and hand surgeons.
