On this internal rotation radiograph, the humeral head (green), greater tuberosity (yellow) and lesser tuberosity (red) are outlined. Normally, these should be the only structures creating outlines. In this case, an additional Hill-Sachs lesion (blue) is visible.
Case Discussion
No pre-reduction radiograph was available, nor was the information specified by the referring physician, but the Hill-Sachs lesion suggests a now-reduced anterior dislocation.
