Final answer:
The most clearly showing projection for a clay shoveler's fracture is Axiolateral hip.
Step-by-step explanation:
The most clearly showing projection for a clay shoveler's fracture is Axiolateral hip. A clay shoveler's fracture is a type of avulsion fracture of a spinous process in the lower cervical or upper thoracic vertebrae. An axiolateral hip projection would provide the best visualization of the injury because it provides a lateral view of the cervical spine, allowing for better visualization of the spinous process fractures.
