Abstract

Background: The biceps brachii is the main muscle at the front of the upper arm. Normally, it has two points of origin at the shoulder and attaches to the radius bone near the elbow, along with a flat tendon sheet called the bicipital aponeurosis. Case Presentation: During a routine dissection of a human body, we found an unusual structure on the left side. The short head of the biceps muscle did not start normally. Instead, its origin was formed partly as a muscle and partly as a tendon- a musculotendinous slip. Conclusion: This type of anatomical variation is important for doctors and surgeons to know. Recognizing it can help prevent accidental damage to nearby nerves and blood vessels. It is also useful during surgery to repair a torn proximal biceps tendon.
