Comprehension: Lateral Radiograph of the Foot
A lateral view of the ankle illustrates the tibiotalar joint. The talar trochlear (dome) is seen. Note the relationship between the talus and calcaneus at the subtalar joint. The cortex of the sustentaculum tali of the calcaneus is outlined, as are the articulations between the navicular, talar, cuboid, and cuneiform bones.
Frontal Radiograph of Ankle
A frontal view of the ankle shows the medial and lateral malleoli. These two structures, as well as the superior aspect of the talus, make up the ankle mortise.
