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.
