In which projection of the foot are the sinus tarsi, cuboid, and tuberosity of the fifth metatarsal best demonstrated?
A. Lateral oblique foot B. Medial oblique foot C. Lateral foot D. Weight-bearing foot |
B.
Medial oblique foot To best demonstrate most of the tarsals and intertarsal spaces (including the cuboid, sinus tarsi, and tuberosity of the fifth metatarsal), a medial oblique is required (plantar surface and IR form a 30° angle). The lateral oblique demonstrates the interspaces between the first and second metatarsals and between the first and second cuneiforms. Weight-bearing lateral feet are used to demonstrate the longitudinal arches |

A. dorsoplantar metatarsals/toes B. tangential metatarsals/toes C. 30° medial oblique foot D. 30° lateral oblique foot |
tangential metatarsals/toes
