For a lateral tibia/fibula projection, which statement about the field of view is true?

• A. The hip joint is required
• B. The knee joint is included
• C. The ankle joint must be excluded
• D. Only the mid-shaft is imaged

Answer: (B)

In this view, you want the field of view to cover from knee to ankle so you can examine the entire tibia and fibula and how they align with the adjacent joints. Including the knee joint is important because fractures can extend into the proximal tibia and involve the knee area; seeing this region helps you assess alignment and rule out joint involvement that could change management. The hip joint isn’t necessary for a tibia/fibula study, and the ankle joint should also be visible to evaluate the distal extent of the bones. Imaging only the mid-shaft would miss potential fracture extension or joint involvement, which is why including the knee is the correct requirement.
