May use intact labrum for capsule plication or tuck. Visual changes noted and healing process may accentuate shrinkage. The posterior portion of the inferior glenohurneral ligament plays an important role in stability when the arm is abducted. The posterior capsule has significant redundancy with a valley between the labrum and the posterior portal entrance. The posterior capsule above the inferior glenohumeral ligament is thin.
Stability requires capsular balance, structural support and dynamic positioning of the glenoid.
