When collocating for an AP foot X-ray, what areas should be included?

When collocating for an anteroposterior (AP) foot X-ray, it is essential to ensure that the entire relevant anatomy of the foot is captured. The correct answer focuses on including the calcaneus, which is the heel bone, as well as the distal phalanx—this is the bone at the tip of the toes. By including these elements, the X-ray can reveal important structures and potential pathologies throughout the entire foot.

The inclusion of soft tissue margins is critical as it provides a comprehensive view, but this is less specific than the other structures mentioned. The focus on both the calcaneus and the distal phalanx ensures that both the hindfoot and toe regions are represented, which is vital for assessing any fractures, dislocations, or other abnormalities that may impact the full function of the foot.

Capturing the proximal tib-fib to mid-foot, while important in other X-rays, does not specifically address the focused area of interest for an AP foot X-ray, which should primarily concentrate on the bones and soft tissues of the foot itself.
