The primary symptom is a painful, aching shoulder of rather nondescript type. With supraspinatus tendinitis, the pain is aggravated when the shoulder is abducted and externally rotated against resistance. With bicipital tendinitis, pain is aggravated when the patient flexes forward against resistance. Acromioclavicular Injuries Usually result from a direct blow or fall on the tip of the shoulder. Partial tear of the joint capsule without joint deformity and minimal ligamentous disruption and instability.
Treatment includes ice, pain medication, a sling for comfort, and early mobilization.
Complete tear of the acromioclavicular ligaments. The AC joint is locally tender and painful with motion. The distal end of the clavicle may protrude slightly upward. Stress radiograph of the AC joint with the patient holding a 10-pound weight in both hands reveals widening of the joint. Complete tear of the acromioclavicular and coracoclavicular ligaments with pain on any attempt at abduction.
