Foot AP
4
Feb

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.

Foot Oblique

Overview

The oblique foot radiograph rotates the foot to separate metatarsal heads and reveal fracture lines. This projection improves visualization of the cuboid and navicular bones. It is routinely obtained with AP and lateral views for complete assessment.

Technique

Rotate the foot approximately 30 to 45 degrees and center the detector to the mid foot. Use tight collimation and a small focal spot for optimal detail. Immobilize the foot and ensure consistent rotation for follow up comparisons.

Clinical Indications

Oblique foot views are indicated for trauma and suspected occult fractures. They help visualize the tarsometatarsal joints and lateral column. Correlate with clinical findings and consider CT for complex injuries.

Image Assessment

Inspect cortical continuity and joint alignment and evaluate for small intra articular fragments. Assess the cuboid navicular and cuneiform bones for injury. Report findings relevant to orthopedic or podiatric management.

Forefoot Weightbearing AP Oblique

Feb

Overview

Weightbearing AP oblique forefoot radiographs assess metatarsal alignment and forefoot deformities under physiologic load. The oblique projection profiles the lateral column and metatarsal heads. These views are useful for hallux valgus and metatarsal pathology assessment.

Technique

Obtain the oblique projection with the patient standing and bearing weight equally. Center to the metatarsal heads and use appropriate exposure for increased soft tissue thickness. Ensure consistent foot rotation for serial comparison.

Clinical Indications

Weightbearing oblique views are indicated for deformity assessment forefoot pain and preoperative planning. They reveal functional alignment and joint subluxation not seen on non weightbearing studies. Orthotic and surgical planning rely on weightbearing imaging.

Image Assessment

Evaluate metatarsal alignment hallux valgus angle and joint congruity under load. Assess for metatarsal head overload and subluxation. Report findings relevant to podiatric or orthopedic management.
