So I am one week prior to my bi-lateral hip replacement. AUGHHHH. I have congenital bilateral acetabula protrusio, left one particularly bad and was fused 38 years ago. Pain is occasional but flexibility is nil, so getting hips replaced. Dr. Bryon Nestor, originally from HSS in New York now here in MN. Major checkmark: Eldest passed her driver's test so yeah! I have a chauffer.
