Rotating the foot 30 degrees medially for a medial oblique view primarily reduces superimposition of which bone?

• A. Calcaneus
• B. Navicular
• C. Cuboid
• D. Talus

Answer: (C)

Rotating the foot medially on an oblique view shifts the lateral column bones into a profile that reduces overlap with the calcaneus. This specifically improves visibility of the cuboid because it sits laterally and is often obscured by the calcaneus in standard views. By turning the foot about 30 degrees, the cuboid is separated from the calcaneus, making fractures or lesions in that bone easier to detect. The navicular and talus are not the primary bones whose overlap is minimized with this particular rotation, so the key gain is the clearer view of the cuboid.
