Loose Shoulder

This condition occurs when the tissue that forms a capsule around the shoulder joint stretches and can no longer effectively keep the ball of the humerus within the shoulder socket. Patients with loose shoulder may experience frequent shoulder dislocations.

Cause

Prior instances of shoulder dislocation, where the ball of the humerus slips out of the shoulder socket, can stretch or tear the soft tissue that forms the capsule. Sports that require repetitive overhand motion such as baseball, volleyball or swimming are a common culprit.

Symptoms

The main symptom is a looseness or feeling of instability in the shoulder, as if it could fall our of place at any moment. This is called apprehension. Some patients may also experience pain, numbness and frequent dislocations of the shoulder.
