Periacetabular Osteotomy

Overview

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.

Preparation

The patient is positioned so that the hip is clearly visible to the physician, and the area is cleaned and sterilized. An IV is administered for general anesthesia.

Accessing the Joint

An incision is made across the hip to allow access to the hip joint, and the pelvis and femoral head are examined. Cuts are carefully made across the ilium, pubis and ischium of the pelvis, freeing the hip socket from the rest of the pelvis.

Repositioning the Hip Socket

The hip socket is rotated so that it is properly aligned with the femoral head. Surgical screws or metal plates are inserted to hold the hip socket in place.

End of Procedure and After Care

The incision is closed with sutures or surgical staples and the hip is bandaged. A hospital stay of four to six days is required, and patients will receive physical therapy. Crutches will be needed for at least eight weeks. Most patients will be able to walk unaided in three months.
