Abstract

Introduction: Variants of Flexor Carpi Ulnaris(FCU) are clinically important as they cause ulnar nerve compression. The present article is documented on the anatomical variation found during routine dissection. FCU had its normal origin and insertion while Accessory flexor carpi ulnaris (AFCU) was found with absence of palmarislongus (PL). Awareness of variations of FCU are helpful in reconstructive surgeries of forearm and hand. Method: The right upper limb of a male cadaver was dissected during routine dissection in the Department of RachanaSharir, J.S. AyurvedMahavidyalaya, GujaratAyurved University. All superficial flexor muscles were exposed. The humeral and ulnar heads of FCU was dissected and AFCU was found having musculotendinous origin and central muscle belly inserting in the pisiform bone with the absence of PL. Relevant photographs were taken for documentation. Result: The FCU has its normal origin and insertion. AFCU had a fleshy-tendinous origin having two heads, the small humeral head arising from the medial epicondyle via the commontendon whereas the ulnar head had its origin from the medial margin of theolecranon. This common tendon is long and continuous into the fleshy belly in the middle part of the muscle and inserted into the pisiform bone. Ulnar vessels and nerve lied lateral to the insertion of the AFCU. There was absence of PL. Conclusion: The variation of AFCU is clinically important for surgeons doing flap surgeries, tendon transfer,for the surgeons dealing with cubital tunnel syndrome and in any operative procedure involving forearm and hand.
