Capsular Injury

The shoulder capsule is the deepest soft-tissue layer in the shoulder and represents the ligaments between the humeral head (ball) and glenoid (socket) of the shoulder joint that gets tight at the extreme ends of shoulder motion to keep the shoulder stable. The capsule ligaments can be torn during glenohumeral dislocation. Additional repetitive activity (throwing, swimming, etc.) can injure or stretch the capsule ligaments resulting in instability. When the capsule ligaments are torn, this often results in uncontrolled shoulder instability (slipping out of place).
