Biceps Insertion Rupture

The biceps muscle is in the front of your upper arm. It helps you bend your elbow and rotate your forearm. It also helps keep your shoulder stable.
Tendons attach muscles to bone. Your biceps tendons attach the biceps muscle to bones in the shoulder and in the elbow. If you tear the biceps tendon at the elbow, you will lose strength in your arm and be unable to forcefully turn your arm from palm down to palm up.

Once torn, the biceps tendon at the elbow will not grow back to the bone and heal. Other arm muscles make it possible to bend the elbow fairly well without the biceps. However, they cannot fulfill all the functions, especially the motion of rotating the forearm from palm down to palm up. This is called supination. Significant permanent weakness during supination will occur if the tendon is not surgically repaired.
