A Hill-Sachs lesion is a cortical depression in the posterolateral head of the humerus, commonly associated with anterior shoulder dislocations. It occurs when the soft humeral head impacts against the relatively hard anterior edge of the glenoid, often requiring surgical intervention if it contributes to recurrent instability.

The humerus is the long bone in the upper arm that runs from the shoulder to the elbow, playing a crucial role in arm movement and support. It connects with the scapula at the shoulder and the radius and ulna at the elbow, forming part of both the shoulder and elbow joints.

Surgical intervention involves the manual and instrumental techniques performed to treat a pathological condition, improve bodily function, or enhance appearance. It requires careful consideration of risks and benefits, informed consent, and often involves a multidisciplinary team for optimal patient outcomes.
