When the patient ulnar-deviates for a PA axial, ulnar-deviated wrist projection, the first metacarpal and radius are aligned, which helps in the visualization of certain wrist structures. The lunate is demonstrated distal to the radius, providing a clear view of its position and condition. The distal scaphoid shifts posteriorly, not anteriorly, due to the ulnar deviation, which is important for assessing scaphoid injuries or abnormalities.
