Summary

This chapter begins with an introduction of the anatomy of the ankle and foot. Appropriateness criteria for imaging foot and ankle trauma are then discussed. The ankle and foot are anatomically distinct from each other and therefore radiographic evaluation of each is different from the other. Standard ankle radiographs include anteroposterior (AP), lateral, and mortise view, and foot radiographs include AP, lateral, and oblique views. Computed Tomography (CT) is used for pre-operative planning in patients with complex distal tibial and malleolar fractures, tarsal fractures and Lisfranc fracture-dislocations. Magnetic Resonance (MR) imaging is indicated in assessment of radiographically occult stress and insufficiency fractures. In the setting of foot and ankle trauma, ultrasound is often performed to evaluate the Achilles tendon for the presence and severity of a tear. The key to interpreting ankle and foot radiographs is familiarity with normal anatomy and injury patterns that may involve the ankle and foot.
