Whether the femoral head disease is curable or not is related to the stage of femoral head disease, as follows: 1, stage 1 and 2 femoral head necrosis: the treatment effect is better, more conservative treatment is used, which is generally through reducing weight bearing, and then muscle exercise around the hip joint, which can increase joint stability and thus reduce joint load. At the same time, the use of alcohol and hormones should be prohibited, and through active conservative treatment, it can be cured; stage 2, 3 or 4 femoral head necrosis: the treatment is relatively more difficult, stage 3 can use the fibula flap transplantation with vascular tip, or iliac flap transplantation with vascular tip, this surgery is the reconstruction of blood flow surgery, the surgery is relatively complex, trauma is also larger, and the patient’s recovery is slower. stage 4 femoral head necrosis Artificial joint replacement surgery is required. Although full function can be restored after surgery, it is done at the expense of the femoral head itself.
