The shoulder joint capsule is the ligament that surrounds the shoulder joint. It stabilizes the shoulder by keeping the head, or ball, of the upper arm bone centered in the glenoid socket in your shoulder blade.
The shoulder capsule can loosen or tear from a light or severe trauma. It can also occur with an overuse injury. Once the ligaments in the joint capsule become loose, shoulder dislocation frequently recurs. Another common name for this condition is shoulder instability.
