Bilateral femoral head necrosis can usually be operated together at the same time, and surgical treatment can effectively treat femoral head necrosis. Patients with severe bilateral necrosis of the femoral head can usually undergo surgery at the same time. Clinically, there are two main types of surgery, one is to preserve the patient’s own femoral head, such as medullary decompression surgery, which can reduce the intraosseous pressure, increase the supply of blood flow, and also remove part of the necrotic bone, and the other is to carry out an artificial arthroplasty, which replaces the loss of the function of the joints. Doctors will choose the appropriate treatment according to the patient’s specific situation. Currently, the surgical techniques are relatively mature and can usually be performed at the same time, with postoperative attention to protection as well as active cooperation with the doctor for rehabilitation training.
