Final answer:
A lateral foot radiographic view is the best option to demonstrate the cuboid, sinus tarsi, and tuberosity of the 5th metatarsal, which are most visible in this perspective.
Step-by-step explanation:
The cuboid, sinus tarsi, and tuberosity of the 5th metatarsal can best be demonstrated using a lateral foot radiographic view. This view allows for a clear image of the lateral aspects of the foot, where these anatomical structures are located. The cuboid is one of the seven tarsal bones that form the posterior foot, and it features a deep groove across its inferior surface for muscle tendon passage. The 5th metatarsal, which is part of the anterior half of the foot formed by the five metatarsal bones, has a prominent tuberosity that can be felt as a bony bump at the midpoint along the lateral border of the foot. The sinus tarsi is a small canal located between the talus and calcaneus bones, and it is best visualized on the lateral view when examining the foot.
