Pelvic and Femoral Osteotomies

Also known as: periacetabular osteotomy, PAO, PAO surgery.

What is hip preservation surgery: pelvic and femoral osteotomies?

The acetabulum is the curved part of the pelvis that forms the hip socket and accepts the head of the femur bone. In most cases, these two bones fit together well. If something is causing the femur to pop loose or not rotate well in the socket, then a pelvic and femoral osteotomy may be the procedures needed to fix the problem.


What happens during the procedure?

In some cases, only a pelvic osteotomy is required. This involves cutting away bone in order to reposition the acetabulum in the pelvis. It is then held in its new position with screws. If a femoral osteotomy is needed, this procedure involves reshaping the femur in order to fit in the pelvis better.


Is any special preparation needed?

The patient may need to avoid food, drink or medication for a set period of time prior to the procedure. Several diagnostic tests are required, as well.


What are the risk factors?

Infection, bleeding, pain, and injury to surrounding organs and tissues are all potential complications of pelvic and femoral osteotomies.
