Which three areas should be visible on a lateral tibia and fibula radiograph?

Which three areas should be visible on a lateral tibia and fibula radiograph?

• A. Anterior tibia; Medial malleolus; Calcaneus
• B. Posterior knee joint; Lateral malleolus; Fibular head
• C. Superimposed femoral condyles; Lateral aspect of the medial malleolus; Lateral aspect of the tibia and fibula
• D. Medial malleolus; Lateral malleolus; Tibial plateau

Answer: (C)

On a lateral view of the tibia and fibula, three areas should be clearly visible to confirm proper positioning and provide diagnostic usefulness. First, the femoral condyles should appear superimposed, showing the knee is in true lateral with minimal rotation and the beam aligned correctly. Second, the lateral aspect of the medial malleolus should be visible, ensuring the ankle region is included and the malleolus is in profile for evaluating distal tibiofibular alignment. Third, the lateral aspect of the tibia and fibula should be seen along the shafts, allowing assessment of fracture lines and any displacement without excessive overlap. Together, these cues indicate the projection is positioned correctly and will yield reliable information about the leg, knee, and ankle.
