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.
