ABSTRACT

In view of the variable presentations of biceps brachii, a proper understanding of the anatomy of the muscle, and possible anatomical variants is a pre-requisite in managing distal biceps injury. We present the case of a 65 years old male cadaver showing variationin the insertion pattern of biceps brachii muscle unilaterally on the left arm. Although the origin of the muscle was normal, its insertion was by two separate tendons; a common and an accessory; both inserting on diverse regions of the radial tuberosity. The common tendon was formed by the tendons from short head and long head. The accessory tendon was the extension of the fleshy belly on the lateral side of the main muscle (Accessory Muscle Belly) towards its lower third. Knowledge of the accessory tendon of the biceps iscrucial while performing tendon reconstruction and repair and it may also lead to unusual displacement of the bone fragment, subsequent to fracture.
