Figure 2 Imaging examinations of case two. A–C: Plain radiographs and three-dimensional computed tomography (3D-CT) reconstruction of the left shoulder, showing multiple intra-articular loose bodies and the subluxation of the humeral head; D–F: Postoperative radiographic re-examination and 3D-CT reconstruction showed no loose bodies in the subacromial space. The humeral head returned to a normal anatomical relationship.
