Abstract

The anatomical variations and abnormalities of the muscles of the upper limb have become significant because of new imaging techniques, such as computed tomography and magnetic resonance imaging. Among the three muscles of the anterior compartment of the arm, a very uncommon anomaly of the biceps is having three or more heads. Knowledge of the existence of the three headed or four headed biceps brachii may become significant in preoperative diagnosis and during surgery of the upper limb. The present study was undertaken to observe the anomalous origin, insertion and the incidence of three or more heads biceps brachii in the adult human cadavers. This study was carried out on 24 human cadavers at Dr. Pinnamaneni Siddhartha institute of medical sciences & research foundation (Dr. PSIMS & R.F) Gannavaram; Krishna Dist; A.P. Variant biceps brachii may cause compression of neurovascular structures because of their close relationship to brachial artery and median nerve. The surgeons and traumatologists have to keep such muscular variations in mind.
