Two surgical approaches are usually taken, either the femur is cut to put the femoral head deeper inside the acetabulum or the acetabulum is cut to make it cover the femoral head better. Rarely, both the femur and the acetabulum will need to be cut. Surgery does not guarantee good outcome. Perthes disease varies from patient to patient. No two cases are identical.
Physicians vary in the way they take care of patients with Perthes disease.
Radiographic monitoring during the stages of Perthes disease is necessary. With appropriate radiographic follow-up, the physician and the family can make appropriate decisions about the treatment.
