Medial ends of the clavicles are at incongruent heights, with the painful right clavicle inferior to the left clavicle, suggesting posterior dislocation of the right sternoclavicular joint.
On frontal projection, the humeral head has a lightbulb appearance. This is due to internal rotation of the shoulder caused by a sling-harness (rather than a posterior dislocation), and congruency of the glenoid and humerus can be confirmed on both frontal and lateral views.
