What x-rays should you order for a shoulder dislocation?

• A. AP, Axillary, and Y-view
• B. AP only
• C. Axillary view only
• D. AP and Lateral

Answer: (A)

The key idea is that shoulder dislocations need a multi-view radiographic approach to not miss the direction of the dislocation and any associated bone injuries. An AP view provides a general picture, but it can miss certain dislocations and small fractures. The axillary view gives an true axial perspective of the shoulder, making it especially effective at identifying the direction of dislocation and occult injuries that AP may overlook, such as a posterior dislocation. The scapular Y view (or Y-view) shows the humeral head in relation to the glenoid in the scapular plane, helping confirm alignment and reveal other injuries like Hill-Sachs or Bankart-type lesions that may not be evident on AP or axillary views alone. Using all three views—AP, axillary, and Y-view—offers the most complete assessment, reducing the chance of missing a dislocation or associated fracture. The other options lack one or more essential views, which can leave important injuries undetected.
