<P> Overuse can lead to a buildup of tissue around the posterior capsule called hypertrophy . The next step is tightness of the posterior capsule called posterior capsular contracture . This type of problem reduces the amount the shoulder can rotate inwardly . </P> <P> Over time, with enough force, a tear may develop in the labrum . The labrum is a rim of cartilage around the shoulder socket to help hold the head of the humerus (upper arm) in the joint . This condition is called a superior labrum anterior posterior (SLAP) lesion . The final outcome in all these steps is the dead arm phenomenon . </P> <P> The shoulder is unstable and dislocation may come next . Dead arm syndrome will not go away on its own with rest--it must be treated . If there is a SLAP lesion, then surgery is needed to repair the problem . If the injury is caught before a SLAP tear, then physical therapy with stretching and exercise can restore it . </P> <P> It is common among baseball pitchers as they age, and it can also occur with quarterbacks in football and handball players also as they age . </P>
