Rotator Cuff Tendinitis/Tear

Rotator cuff diseases include inflammation (tendonitis) and possibly a partial- or full-thickness tear of the tendon. This causes marked pain in the shoulder region, which may worsen at night or with activities in which the arms are held over the head. Rotator cuff problems are caused by cumulative trauma throughout one's lifetime. It is believed to be partially caused by impingement of the tendon on a bone spur within the shoulder. Rotator cuff tendonitis or tear is fairly common. It is usually detected by means of placing the shoulder through ranges of motion that reproduce the pain.
