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.
