Proximal biceps tendon rupture: primarily an injury of middle age.

A 51-year-old man suffered a rupture of the long-head tendon of the left biceps and a small rotator cuff tear while rock climbing. The typical signs and symptoms of a ruptured long-head biceps tendon include anterior shoulder pain, tenderness in the bicipital groove, and unusual bulging of the injured biceps. The history and physical exam are generally sufficient to make the diagnosis, but x-rays and MRI may be helpful to rule out related disorders. Because the injury is often associated with rotator cuff tendinitis, a complete shoulder exam is necessary. Conservative treatment will enable most patients to regain normal strength.
