The treatment of femoral head necrosis is mainly aimed at the etiology, especially in the early stage. If the femoral head necrosis is caused by alcoholism, you must give up drinking. If the necrosis of femoral head is caused by the use of hormones, it may be necessary to discuss with the competent doctor or attending doctor whether hormones can be reduced or stopped. Second, symptomatic treatment. Pain symptoms often appear in the early stage of femoral head necrosis, so it is more important to use non-steroidal anti-inflammatory painkillers, which can better alleviate the pain symptoms of patients, but this treatment is not the treatment of the cause of femoral head necrosis, but only the relief of symptoms. In this case, it may be helpful to use drugs that promote blood circulation. Furthermore, it is necessary to reduce the load on the hip joint, such as using braces and crutches to reduce the load and prevent the femoral head from collapsing and deforming. After the collapse and deformation of the femoral head, its cartilage can also be damaged, and proper use of drugs to nourish the articular cartilage surface can also be helpful. In addition, if the femoral head necrosis develops to stage ⅲ or ⅳ, the condition will be more serious. At this time, if the patient is young, it may be necessary to do hip preservation treatment, that is, to preserve the femoral head. There are many surgical methods, such as drilling decompression and packing bone grafting, but the effect is not particularly obvious. All the treatments are aimed at preventing the further development of femoral head necrosis and delaying the time of joint replacement. Therefore, hip replacement is inevitable after joint collapse and deformation. At present, with the improvement of artificial joint technology and surgeon's operation technology, artificial joint surgery is very mature, so the effect of later artificial joint replacement is better.
