A Hill-Sachs defect is commonly seen in patients with anterior shoulder dislocations, due to the impact from the humeral head against the anterior glenoid rim¹.

As the defect is on the posterior aspect of the humeral head, it may not always be present on an anterio-posterior radiograph of the shoulder, especially if it was performed with an external rotation of the humerus. Therefore, a Stryker notch radiograph would be helpful in assessing the severity of the Hill-Sachs defect². Other views that would demonstrate the Hill-Sachs defect would be an anterio-posterior radiograph with an internal rotation of the humerus³.
