There are two types of treatment for femoral head necrosis, non-surgical and surgical. (A) Non-surgical therapy: 1. Restriction of weight-bearing. It can reduce the pressure on the femoral head, relieve the pain, and avoid the collapse of the femoral head and the aggravation of collapse. 2. Traction therapy. Such as ankle sleeve traction can relieve the spasm of soft tissues, reduce intra-articular pressure, thus improving blood circulation and reducing pain; and can correct some deformities, such as joint deformity caused by contracture of soft tissues of serious sub. 3.Intravenous injection of salvia, etc. Salvia has the function of regulating lipid metabolism, lowering blood lipids, improving the high viscosity of blood, reducing the damage of vascular endothelial cells, inhibiting coagulation, dilating peripheral blood vessels, increasing blood volume and improving microcirculation, so as to improve the blood circulation within the femoral head and treat ischemic necrosis of the femoral head. 4.Therapeutic treatment by Chinese medicine. According to TCM, the disease is centered on “stasis” and can be divided into Qi stagnation and blood stasis, phlegm and blood stasis, Qi deficiency and blood stasis, spleen and kidney Yang deficiency, liver and kidney deficiency and other types of evidence. In the early stage, the disease is mainly solid, and in the later stage, it is mainly deficiency, mostly mixed with deficiency and intermingled. (II) Surgical treatment: According to the different stages of the disease, different surgical methods can be chosen. 1. Drilling and decompression surgery. It is a minimally invasive surgery, less painful, quick recovery, no need to meet the needle, does not affect the normal structure of the hip joint, can better reduce pain, control the development of necrosis and improve the quality of life, applicable to the treatment of patients with stage I and II femoral head necrosis. 2.Marrow core decompression plus artificial bone grafting. Bone grafting is divided into autologous bone grafting and artificial bone grafting. Through the navigation and positioning system, the femoral head is decompressed and the dead bone is scraped away, and then bone blocks or bone particles are implanted to play the role of mechanical support and promote the crawling of new bone, which is conducive to the repair and reconstruction of femoral head necrosis, and is suitable for patients with stage I and II femoral head necrosis. The artificial bone implant does not require separate surgery to retrieve bone and will not cause bone deficiency, which can make the surgery simpler. 3.Tantalum rod (porous tantalum metal) implantation. It can be done with minimally invasive technique and without donor area lesion. It can treat the early stage of femoral head necrosis. It is used for young patients whose X-rays show cystic necrosis of the femoral head, which has not yet collapsed, and the patient needs to walk normally. This treatment can avoid or delay the collapse of the femoral head and has the possibility of delaying or avoiding joint replacement. 4. Vascular grafting. Vascular grafting can provide good blood flow to the femoral head, but the mechanical support for the femoral head is poor, and is suitable for the treatment of patients with stage I and II femoral head necrosis. 5.Bone grafting with myotomy. Bone grafting with muscle vessels can effectively provide blood supply to the femoral head. The operation can reduce the internal pressure of the femoral head, remove the dead bone, implant new bone, play the role of osteoinduction, and play a supporting role for the femoral head. It is suitable for the treatment of patients with stage II and III femoral head necrosis. 6.Femoral head replacement or hip arthroplasty. Artificial joint replacement uses artificial materials to replace the necrotic, deformed and hyperplastic femoral head and acetabulum to improve their functions, and is adapted to the treatment of patients with stage IV and joint dysfunction.
