Why is it important?
The coracobrachialis muscle is a muscle of armthat shows several variations in its attachments. It isinserted into the middle 5 cm of the medial border ofthe humerus. The median nerve crosses the brachial artery from lateral to medial near the insertion ofcoracobrachialis and enters the cubital fossa. Thenerve and the artery may vary in their course This study was conducted in 36 embalmed adult upper limbs of both sexes of age group between 50–80 years from the Department of Anatomy, KMC, Chennai were studied. In this study, a musculoaponeurotic tunnel formed by coracobrachialis muscle was observed in 2.8% of the specimen in which entrapment of brachial artery and median nerve was present. The abnormality reported in the present study maylead to neurovascular compression syndrome in the upper limb. Knowledge of anatomical variations in the muscular structure and its related neurovascular entrapment is important surgically for orthopaedic surgeons, plastic surgeons and also physiotherapists clinically.
