Which projection is described by rotating the foot 30 degrees medially?

• A. AP axial foot
• B. Lateral foot
• C. AP foot
• D. Medial oblique foot

Answer: (D)

Rotating the foot medially about 30 degrees places it in a medial oblique position. In this view the plantar surface angles toward the midline, which reduces overlap of the bones and lets the joints between the tarsal bones be seen more clearly. This projection is used specifically to better visualize the arrangement of the midfoot and forefoot bones and their joints, something that isn’t as clear in a straight AP view or in a true lateral. The AP axial view relies on an angled CR to open spaces and isn’t defined by this medial rotation, and a lateral view results from a side-positioning of the foot, not from medial rotation. So, 30-degree medial rotation yields the medial oblique foot projection.
