Which statement best describes acceptable patient placement for plantodorsal axial calcaneus radiography?

• A. The foot may be positioned seated or lying
• B. The patient must be standing
• C. The patient must be prone
• D. The patient must be in a supine position with the knee flexed

Answer: (A)

For the plantodorsal axial calcaneus view, the goal is to direct the x-ray beam along the long axis of the calcaneus while the foot is dorsiflexed so the plantar surface faces the image receptor. This setup provides a clear axial projection of the calcaneus, including the tuberosity and subtalar joint, without unnecessary distortion or overlapping structures. That’s why this view is commonly obtained with the patient seated or lying down—the position is stable and permits the necessary dorsiflexion of the foot. Standing isn’t required and isn’t needed to achieve the correct alignment, making seated or lying the acceptable placements.
