Weightbearing Foot AP Lateral
4
Feb

Overview

Weightbearing foot radiographs assess alignment and joint space under physiologic load. AP and lateral weightbearing views reveal flatfoot cavus deformity and joint collapse not seen on non weightbearing studies. These views guide orthotic and surgical planning.

Technique

Obtain AP and lateral radiographs with the patient standing and bearing equal weight on both feet. Center the detector to the mid foot and use appropriate exposure for increased soft tissue thickness. Ensure consistent foot positioning for serial comparison.

Clinical Indications

Weightbearing foot views are indicated for deformity assessment hallux valgus and arthritis evaluation. They reveal functional collapse and alignment issues relevant to treatment. Non weightbearing views may underestimate deformity severity.

Image Assessment

Evaluate arch height talonavicular coverage and metatarsal alignment under load. Assess joint space narrowing and subluxation. Report findings relevant to orthotic prescription and surgical planning.

Foot AP

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 Lateral

Feb

Overview

The lateral foot radiograph profiles the longitudinal arch calcaneus and tarsal alignment. The foot is positioned in true lateral with the medial and lateral aspects superimposed. This view is important for assessing arch collapse and calcaneal fractures.

Technique

Place the foot in true lateral and center the detector to include the calcaneus and metatarsals. Use appropriate exposure and immobilize the foot to minimize motion. Weightbearing lateral views assess functional alignment.

Clinical Indications

Lateral foot is indicated for trauma suspected calcaneal fracture and arch assessment. It complements AP and oblique views for comprehensive evaluation. Weightbearing studies evaluate functional deformities.

Image Assessment

Evaluate calcaneal morphology talar alignment and plantar arch height. Inspect for posterior facet fractures and subtalar joint involvement. Document findings relevant to surgical planning and orthotic management.

Foot Oblique

Feb

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.
