title: Anomalous fascicle of triceps brachii muscle and its clinical importance in relation to radial nerve entrapment.
abstract: We present a case of unreported morphological variant of the triceps brachii muscle which was observed while dissecting a cadaveric upper limb at the department of human anatomy. It was noted that an anomalous fascicle present between the lateral and long heads of the triceps. The fascicle was passing just superficial to the spiral groove and was crossing the radial nerve and profunda brachii artery. After the literature search, it was found that the present variation has not been previously reported. The clinical implication of this anomalous fascicle in relation to radial nerve entrapment and non-traumatic radial nerve palsy are discussed.
