Hill-Sachs lesion is associated with dislocation of which joint?

• A. Radiocarpal joint
• B. Elbow joint
• C. Acromioclavicular joint
• D. Glenohumeral (shoulder) joint

Answer: (D)

Hill-Sachs lesion comes from an impact injury of the humeral head when the shoulder bone dislocates anteriorly from the glenoid. As the humeral head slides out of the socket, it strikes the rim of the glenoid, leaving a dent on the posterolateral surface. This makes it a hallmark of dislocation at the glenohumeral joint, i.e., the shoulder joint. The other joints listed are not involved in producing this lesion.
