For an AP tibia/fibula radiograph, which joints should be included in the image?

• A. Knee joint and ankle joint
• B. Hip joint and knee joint
• C. Only the mid-shaft
• D. Knee joint only

Answer: (A)

In a tibia/fibula AP view, you need to see the joints at both ends to properly assess injury and alignment. The tibia and fibula extend from the knee to the ankle, so fractures can extend into or affect the nearby joints. Including the knee joint proximally and the ankle joint distally allows you to check for intra-articular involvement, assess joint-space congruity, and determine any displacement that could influence treatment and prognosis. The hip isn’t part of this view and adding it wouldn’t help evaluate the tibia/fibula or the joints involved. Focusing only on the mid-shaft or on a single end risks missing joint involvement or misjudging alignment.
