Most commonly dislocated large joint — 95% anteriorly. Conditions include impingement, rotator cuff tears, instability, and adhesive capsulitis.

Pathology

Common Injuries & Conditions

Anterior Dislocation

Humeral head displaced anterior to glenoid from abduction-external rotation, often creating a Bankart labral lesion with high recurrence in young athletes.

Shoulder Impingement

Rotator cuff and bursal compression beneath the coracoacromial arch producing a painful arc of abduction.
