Periacetabular Osteotomy (PAO)

Periacetabular Osteotomy (PAO)

Periacetabular Osteotomy (PAO) is a surgical treatment for hip dysplasia that involves repositioning the acetabulum (socket) into a location that best covers the femoral head. “Periacetabular” means around the acetabulum. “Osteotomy” means to cut bone.

This surgical procedure is designed to relieve pain and instability of the hip caused by an abnormally shallow hip socket. In this procedure, the socket is cut and freed from the pelvis, then repositioned at an angle that stabilizes the hip and provides adequate support for the femoral head.
