How many degrees should the foot be rotated for an oblique foot projection?

• A. 15-20
• B. 50-60
• C. 30-45
• D. 65-75

Answer: (C)

Rotating the foot into an oblique position places the tarsal bones in profile and reduces overlapping of the joints, which is essential for clearly visualizing the intertarsal spaces and the cuboid/navicular areas. The standard amount of internal (medial) rotation is about 30 degrees. In clinical practice, a range around 30 to 45 degrees is commonly used to accommodate different patients while still achieving a true oblique view. If rotation is less than about 30 degrees, the foot won’t be obliqued enough, and the joints between the tarsals may remain overlapped. If rotation is much greater—toward 50–60 degrees or more—it becomes a more extreme oblique and can distort or obscure the view, not giving the intended demonstration of the oblique anatomy.
