Humero - bicipito - articularis: a rare accessory muscle of the arm

ABSTRACT

Anomalies related to the musculature of the upper limb are extremely important for plastic and orthopedic surgeons in their clinical practice. The present study reports the presence of a rare accessory muscle in the flexor compartment of the arm with its morphological description and also highlights its clinical relevance. We encountered a rare accessory muscle in the region of upper arm of an adult male Indian cadaver in the Anatomy department. The anatomical details of this accessory muscle were studied in detail and appropriate photograph was taken. An accessory muscle in the flexor compartment of the right upper arm was observed. The muscle originated from the proximal part of the humeral shaft and displayed insertion into the lateral border of the short head of biceps brachii It's fibers also blended with the fibrous capsule of the shoulder joint. The plethora of muscular variations in this important anatomic area is of utmost significance to the surgeon performing reconstructive and explorative procedures
