What does the PA wrist X-ray primarily assess?

The PA wrist X-ray is primarily designed to assess fractures and dislocations of the wrist. This imaging technique allows for a clear view of the carpal bones, distal radius, and the alignment of the wrist joints. By obtaining a posteroanterior (PA) projection, radiologists can effectively evaluate any acute injuries, such as fractures that may not be visible through clinical examination alone. The PA view helps to identify subtle fractures, joint alignment issues, and any associated dislocations, making it an essential tool in the initial assessment and diagnosis of wrist trauma.

While other options relate to different aspects of wrist evaluation, they do not capture the primary focus of a PA wrist X-ray, which is to visualize the skeletal structure for signs of acute injury rather than emphasizing soft tissue, bone density, or chronic conditions like overuse syndromes.
