Abstract

RAO K. G, Mohandas; BHAT, Seetharama M; VENKATARAMANA, V  and  RODRIGUES, Vincent. Ulnar and Humeral Heads Forming Separate Bellies: A Rare Case of Digastric Flexor Carpi Ulnaris Muscle. Int. J. Morphol. [online]. 2009, vol.27, n.1, pp.31-34. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022009000100005.

Proper knowledge of muscular variations is essential for both anatomists and surgeons. Variations of the flexor carpi ulnaris (FCU) are not very common. We are reporting an unusual case of FCU muscle with two bellies. The two heads (ulnar and humeral) of the muscle continued as two separate bellies and the tendons of which joined each other slightly proximal to the wrist before getting inserted to pisiform bone. Further, detailed literature review of variations of FCU muscle is done and the developmental basis for the variation and its surgical importance are discussed.

Keywords : Flexor carpi ulnaris muscle; Variations of forearm muscles; Ulnar head; Humeral head.
