Abstract

Normally, brachioradialis originates from the upper part of the lateral supracondylar ridge of the humerus. Variations in its origin are very rare. We observed the presence of an additional set of fl eshy muscle fibers in the lateral part of the anterior compartment of the arm in addition to the other normal muscles. This unusual case was observed at the Mookambika Institute of Medical Sciences, Kulashekara, Tamil Nadu, India, during routine dissection of the upper limb. The anomalous fl eshy fi bers were attached proximally to the middle part of the shaft of the humerus, close to the insertion of deltoid. Some of its fi bers continued further up to the acromian process of scapula. These fi bers passed downwards along with deltoid and joined the fi bers from the humerus before getting merged with the brachioradialis distally. These additional muscle fi bers were compared with the brachioradialis accessorius and the uniqueness, functional signifi cance and the clinical relevance were discussed.
