Ans.B. A Hill-Sachs lesion is a cortical depression in the posterolateral head of the humerus bone. It results from forceful impaction of the humeral head against the anteroinferior glenoid rim when the shoulder is dislocated anteriorly. It is often associated with a Bankart lesion of the glenoid (anterior capsule injury associated with tear of glenoid labrum of the anterior glenoid rim).
