Biceps Tendon Rupture
This condition is a tear of one of the tendons that anchor the biceps muscle to the shoulder. The upper end of the biceps muscle is divided into two separate sections called the long head and the short head. The long head passes over the head of the humerus and attaches to the glenoid. The short head passes in front of the humerus and attaches to a bony protrusion, called the coracoid, on the shoulder blade.
