The medial oblique projection at a 45° angle is the best choice for demonstrating the distal tibiofibular joint because this positioning allows for optimal visualization of the joint space. When the ankle is rotated medially, the fibula moves away from the tibia, opening up the area around the distal tibiofibular joint. This positioning reduces superimposition of the bones and highlights the joint relationship, which is crucial for assessing any injuries or conditions affecting the syndesmosis between the tibia and fibula.

The other projection options do not specifically target this joint as effectively as the medial oblique. For instance, the lateral oblique does not provide the same level of detail for the distal tibiofibular joint because it does not separate the tibia and fibula in the same manner. The anteroposterior projection primarily shows the overall structure of the ankle but lacks the specific angle required to properly assess the distal tibiofibular joint. Lastly, the posterior oblique projection may also fail to properly visualize this joint because it is more focused on the posterior aspects of the ankle rather than the lateral area where the distal tibiofibular joint is located. Therefore, the medial oblique at 45° is the most effective
