Overview

The lateral ankle radiograph profiles the talus calcaneus and distal tibia to assess alignment and fractures. The foot is positioned in true lateral with the medial and lateral malleoli superimposed. This view is essential for trauma and preoperative planning.

Technique

Position the ankle in true lateral and center the detector to include the distal tibia and calcaneus. Use appropriate exposure and immobilize the limb to minimize motion. Include the subtalar joint when indicated.

Clinical Indications

Lateral ankle is indicated for trauma suspected fracture and evaluation of hindfoot alignment. It complements AP mortise and oblique views for comprehensive assessment. CT is used for complex fractures and surgical planning.

Image Assessment

Evaluate talar dome integrity calcaneal alignment and posterior malleolar involvement. Inspect for joint effusion and soft tissue swelling. Report findings relevant to orthopedic management and fixation planning.
