Overview
The AP foot radiograph evaluates metatarsals tarsals and phalanges for fractures and alignment. The patient places the plantar surface flat on the detector with the foot dorsiflexed slightly. This view is standard for foot trauma and deformity assessment.
Technique
Center the detector to the base of the third metatarsal and ensure the foot is flat without rotation. Use appropriate exposure and immobilize the foot to reduce motion. Include the ankle when indicated for proximal pathology.
Clinical Indications
AP foot is indicated for trauma pain and suspected metatarsal fractures or dislocations. It assesses arch alignment and foreign bodies. Additional oblique and lateral views complement the AP projection.
Image Assessment
Inspect cortical margins for fracture lines and evaluate joint spaces for subluxation. Assess for Lisfranc injury and metatarsal alignment. Report findings relevant to orthopedic or podiatric management.
