Radiograph of the right shoulder AP view showing destruction of the head of the humerus giving rise to its blunted amputated appearance and increased joint space. The proximal right humerus and glenoid cavity are sclerosed and the proximal humerus is subluxated superiorly. Multiple bony fragments are seen in the soft tissues around the right shoulder joint.

A repeat X-ray was done that showed destruction of the head of the right humerus leading to its typical blunt amputated appearance and increased joint space [Figure 1].
MRI of right shoulder. (a) Sagittal proton density fat suppressed image showing destruction of the head of the humerus with sharp margins and large amount of joint effusion. (b) Coronal T2 weighted image showing superior subluxation of the head of the humerus with multiple bony fragments. Destruction of surrounding muscles is also noted.
