BICEP TENDON RUPTURE

Located on the front side of the upper arm, the biceps muscle attaches to the bones of the shoulder and elbow by tendons. While uncommon, biceps tears on the elbow side most often occur from sudden injuries rather than through overuse. The bicep tears that occur from injuries also tend to result in greater weakness afterwards  than similar biceps injuries at the shoulder level.

Unfortunately, If the biceps tendon tears at the elbow, it will not reattach to the bone and heal on its own. Patients will still retain most functions of the arm thanks to the other muscles, though they will have the most difficulty rotating the forearm from the palm down position to the palm up position (Supination). 

To regain normal levels of  arm strength, Doctors must usually resort to surgery. However, for patients who may not need total arm function, patients may sometimes settle for nonsurgical treatment.
