Which ankle projection shows the distal tibia superimposed over the distal fibula?

The projection that demonstrates the distal tibia superimposed over the distal fibula is the lateral ankle view. In this positioning, the ankle is rotated in such a way that the lateral side faces the image receptor. This alignment allows for an optimal view of the bony structures of the ankle joint, showing the distal ends of the tibia and fibula in a superimposed manner. The lateral view provides critical information regarding the integrity of the joint and any potential fractures or dislocations.

In contrast, the other projections offer different views of the ankle; the anteroposterior view provides a frontal perspective, allowing visualization of the joint as a whole but without the superimposition characteristic of the lateral view. The medial oblique view demonstrates the ankle in a rotated position, improving visualization of the medial aspects of the joint but not achieving the specific superimposition of the distal tibia and fibula. The stress ankle projection is utilized to assess the ankle under load or rotational forces, primarily to evaluate ligament instability, and does not emphasize the bony superimposition of the distal tibia and fibula.
