Axillary lateral or scapular "Y" view can help distinguish between<unk>  and posterior dislocation
Rule out associated fracture
May forego imaging if:
Age <40
Atraumatic mechanism
Multiple past dislocations
Clinically consistent with dislocation
Bedside ultrasound can be used to assess for both dislocation and successful reduction
