How to treat ischemic femoral head necrosis

In addition to bacterial infection, femoral head necrosis is also caused by ischemia. Many people believe that ischemic necrosis of the femoral head is not life-threatening, but this is a wrong view. If ischemic femoral head necrosis is left untreated, it will cause certain damage to the body's bone and living tissue. Therefore, we must treat ischemic necrosis of the femoral head in a timely manner. Now let me tell you how to treat ischemic necrosis of the femoral head.

1. Non-surgical treatment. 1. Limit the weight. Strictly limiting weight-bearing or not bearing weight can restore blood supply to ischemic bone tissue and protect it from pressure, thereby controlling the progression of the disease, preventing collapse, and promoting self-healing of the ischemic and necrotic femoral head. It is mainly suitable for patients who are not suitable for surgical treatment, such as the elderly, patients in poor general condition, patients in the advanced stage of ischemic necrosis and patients with poor prognosis. You can first rely on braces such as canes and crutches to limit the load on the affected limb until there is a clinical indication for joint replacement.

2. Electrical stimulation. Electrical stimulation has an osteogenesis effect and can promote fracture healing. Its mechanism may be related to the piezoelectric effect of bone and the ability of electrical stimulation to simulate biological signals. Electrical stimulation can be used as an independent treatment for ischemic necrosis or as an adjunct to surgery.

2. Surgical treatment. Treatment for preserving the femoral head: 1. Drilling decompression. It is mainly used for patients in the early stage without articular surface collapse and is the simplest surgical method for treating femoral head necrosis. The mechanism of action is to reduce intraosseous pressure and promote venous return. Relieve the spasm of the nutrient vessels and allow new blood vessels to grow into the ischemic area through the bone holes.

2. Bone grafting. Because drilling is required before bone grafting, it is also called drilling decompression bone grafting. Its mechanism of action is: drilling to decompress; bone grafting to provide mechanical support; muscle pedicled bone transplantation to increase blood supply to the femoral head. There are many surgical methods, including cancellous bone transplantation, cortical bone transplantation, muscle pedicled bone transplantation, vascular anastomosis bone transplantation and allogeneic osteochondral transplantation. In the early stage, central decompression and cortical bone implantation were often used to treat femoral head necrosis.

3. Osteotomy. By changing the corresponding position relationship between the femoral head and the femoral shaft, the weight-bearing area of ​​the femoral head can be increased.

I believe everyone has a certain understanding of how to treat ischemic necrosis of the femoral head. During the treatment process, we must also maintain a positive attitude to fight the disease, quit smoking and drinking, avoid spicy food, eat more foods that nourish the spleen and kidneys, strengthen muscles and bones, supplement calcium and promote blood circulation. Finally, the editor wishes the patient a speedy recovery.
