In which projection are the cuboid articulations, sinus tarsi, and tuberosity of the fifth metatarsal best demonstrated?

The best demonstration of the cuboid articulations, sinus tarsi, and tuberosity of the fifth metatarsal occurs in the AP oblique foot with medial rotation. This projection allows for optimal visualization of the lateral aspect of the foot, where these specific structures are located.

In the AP oblique view, by rotating the foot medially, the cuboid bone and its articulations can be better seen, as this angle reduces superimposition of surrounding structures. Additionally, the sinus tarsi, an important landmark for assessing ankle injuries, is more readily discernible in this orientation. The tuberosity of the fifth metatarsal, which is often a point of interest in studies or injuries related to the foot, can also be clearly identified in this projection due to the reduction of overlapping bones that occurs with the medial rotation.

While other projections like the lateral projection provide a side view of the foot, they do not enhance the visibility of these specific structures as effectively. The AP projection of the foot does not allow for sufficient visualization of the lateral structures due to overlapping. The calcaneus projection focuses primarily on the heel bone, which is not relevant for demonstrating the cuboid articulations or the sinus tarsi. Therefore, the
