Operational procedures for creating the femoral head necrosis model. A Selection of the iliac crest and greater trochanter as the sites for an arched incision; B Sequential dissection of muscle and other soft tissues to expose the acetabulum; C Create a window approximately 3Â mm away from the acetabular rim; D Implantation of the femoral head compression device. E Intraoperative X-ray imaging confirms the accurate placement of the bone window
