Which projection demonstrates the distal tibia aligned with the distal fibula?

• A. AP ankle
• B. Mortise
• C. Medial oblique
• D. Lateral ankle

Answer: (D)

The main idea is that the lateral ankle view shows the distal ends of the tibia and fibula in true alignment. In this projection, the leg is placed so the tibia and fibula lie in the same plane, and their posterior margins are superimposed. That clear superimposition lets you verify that the distal tibia sits in line with the distal fibula and readily spot any diastasis or misalignment at the ankle or near the syndesmosis. Other views—AP, mortise, or medial oblique—alter the bones’ positions or emphasize joint surfaces rather than the direct distal alignment, making the lateral view the best choice to demonstrate whether the distal tibia is aligned with the distal fibula.
