case_images: Therefore, the patient was believed to have experienced posterior shoulder dislocation, and the clinical diagnosis was confirmed by radiological imaging (Fig. 1).

case_images: However, during this procedure, because the osteoporotic humerus showed a collapse of approximately 30% on the posterior articular surface, an iatrogenic Hill-Sachs lesion was added to the reverse Hill-Sachs lesion at the beginning of the humeral head (Fig. 2).

case_images: Considering the possibility that this partial engaging lesion could develop into a non-engaging lesion, fixation was performed with a Kirschner wire, while the joint was in the reduction position (Fig. 3).

case_images: The measurements revealed a defective area of approximately 25% in the anterior part of the humeral head and 30% in the posterior part (Fig. 4).
