A Bankart lesion is defined as which of the following?

• A. Avulsion of the glenoid labrum
• B. Partial thickness rotator cuff tear
• C. Avulsion of the acromion
• D. Damage to rotator cuff tendons

Answer: (A)

Bankart lesion describes tearing where the glenoid labrum peels off from the front-inferior rim of the glenoid, usually after an anterior shoulder dislocation. The labrum is the fibrocartilaginous rim that deepens the socket and helps stabilize the joint by anchoring the capsule and ligaments. When it avulses off the glenoid, the stabilizing structure is lost, leading to instability and a tendency for recurrent dislocations. This is not related to the rotator cuff or the acromion, which is why injuries to those structures aren’t Bankart lesions.
