I am a 40 year old mother of 2 boys - Brady and Reilly. I have a wonderful husband TJ. I was diagnosed with hip dysplasia at age 28 and had a scope done to repair a torn labrum. After two pregnancies and lots of hip pain - I had RPAO on 1/25/08 with Dr. Millis in Boston.
"Periacetabular" means around the acetabulum. "Osteotomy" means to cut bone. Simply put, the PAO cuts the bone around the acetabulum that joins the acetabulum to the pelvis. Once the acetabulum is detached from the rest of the pelvis by a series of carefully controlled cuts, it is rotated to a position of ideal coverage as dictated by the specific acetabulum's unique anatomy.
