Comprehension: CT of Ankle Joint
Two coronal oblique CT sections of the ankle are shown. The more posterior section defines the bony relationships around the tibiotalar joint. The subtalar joint is also well shown. The more anterior section brings out the sustentaculum tali of the calcaneus, as well as the head of the talus. Note that both structures are on the medial aspect of these bones. CT examination of the tarsal bones is sometimes required to bring out subtle fractures as well as major displacements of fracture fragments.
