A dislocation is when the ligaments that hold the bones of a joint together are stretched and the bones separate. A shoulder dislocation causes the top of the upper arm bone (humerus) to slip out of its normal position in the shoulder socket.
The shoulder can become dislocated due to a blow to it or the upper arm, or when the shoulder gets pulled while the arm is reaching out, which often happens during sports.
A dislocated shoulder may move back into place on its own, or a doctor might gently put it back with a maneuver called a reduction. If a reduction is needed, medication is given to make the person comfortable during the maneuver.
A shoulder immobilizer or sling is usually worn for a few weeks. After the immobilizer is taken off, physical therapy is generally needed to improve shoulder strength and motion. Usually, people return to most normal activities within a couple of months, although a return to full sports participation can take longer.
