Learn about shoulder dislocation and surgeries to prevent further dislocation

Traumatic Anterior Shoulder Instability is traumatic shoulder injury that generally occur as a result of an anterior force to the shoulder while its abducted and externally rotated and may lead to recurrent anterior shoulder instability.

Bankart tear - is an avulsion of the anterior labrum and anterior band of the IGHL from the anterior inferior glenoid

Hill Sach's defect - is a chondral impaction injury in the posterosuperior humeral head secondary to contact with the glenoid rim

Development of Bankart tear and Hill Sach's defect can lead to recurrent shoulder dislocations and further damage to the capsule and other anatomical structures of the shoulder like - Bony Bankart lesion, Humeral avulsion of glenohumeral ligament, glenoid articular defects  

Diagnosis is made clinically with the presence of positive anterior instability provocative tests and confirmed with MRI studies that may reveal labral and/or bony injuries of the glenoid and proximal humerus (Hill-Sachs lesion).
