Which projection will demonstrate the cuboid, navicular, and lateral cuneiforms without superimposition?

The AP oblique projection in 30-degree medial rotation is the correct choice for demonstrating the cuboid, navicular, and lateral cuneiform bones without superimposition. This specific angle allows for optimal visualization by placing these bones in a position where they are not overlapped by adjacent structures.

When the foot is rotated medially by 30 degrees, the cuboid and lateral cuneiform are positioned laterally, while the navicular is brought into clearer view medially. This technique ensures that the anatomy of interest can be distinctly visualized, which is essential for accurate diagnosis and evaluation.

The AP projection, while a standard view, does not provide the necessary separation of these middle and lateral tarsal bones, often leading to their superimposition. The lateral oblique projection typically focuses on the medial structures of the foot and would not adequately visualize the cuboid or lateral cuneiform as intended. Similarly, the AP oblique projection in 30-degree lateral rotation would favor visualization of the medial bones of the foot rather than the lateral bones, thereby missing the goal of demonstrating the cuboid and lateral cuneiform clearly.
