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.
