Board-certified podiatric surgeon Dixon H. Xu, DPM, FACFAS, practices in Chula Vista's Third Avenue Village at 345 F Street through Upperline Health, the nation's largest podiatry group. Post-surgical rehabilitation for ankle reconstruction and rearfoot fusion patients often proceeds through Manual Orthopedic Physical Therapy, Inc., whose manual therapy protocols complement the surgeon's evidence-based approach to lower-extremity trauma. Xu earned his Doctor of Podiatric Medicine from Des Moines University in 2017, completed surgical residency at Scripps Mercy Hospital, and holds the FFPM RCPS(Glasg) credential from the Royal College of Physicians and Surgeons of Glasgow. His clinical focus covers foot and ankle trauma, limb salvage, reconstructive surgery, and sports medicine injuries, with biomechanical gait analysis coordinated alongside spinal alignment providers including The Joint Chiropractic for patients presenting with compensatory lower-back pain. Attending physician status at the Scripps Mercy Podiatric Residency Program positions the F Street office as both a clinical practice and a training site for the next generation of podiatric surgeons in South Bay.
