Shoulder dislocation with Hill Sachs deformity

AP (image 1) and scapular Y (image 2) images of the shoulder show an anterior shoulder dislocation with Hill-Sachs deformity (arrowhead on image 1 and arrow on image 2). A Hill-Sachs deformity is an impaction fracture caused by the anteroinferior glenoid impacting upon the posterolateral humeral head.

AP (image 1) and axial (image 2) radiograph of the shoulder shows anteroinferior dislocation of the glenohumeral joint. Shoulder dislocations most commonly occur in the anterior direction. Radiologist should evaluate for associated injuries such as a Hill-Sachs deformity which is caused by impaction of the humeral head upon the glenoid.

Sagittal T1-W MRI shows a Hill Sachs deformity of the humeral head.
A Hill Sachs deformity is a compression fracture caused by anterior dislocation of the shoulder. The compression is caused by impaction with the inferior aspect of the glenoid. Patients with a Hill Sachs lesion are thought to be more likely to have recurrent dislocations.

X-ray shows anterior dislocation of the right shoulder. The humeral head is displaced inferiorly and anteriorly in relation to the glenoid. The glenoid has caused an impaction injury of the posterolateral humeral head (Hill Sachs deformity). This image nicely shows the glenoid resting in the Hill sachs deformity. #MSKMonday
