The theory of Chinese medicine is profound and profound, and it must be acknowledged that Chinese medicine has made a great contribution to the health of people in China and the world. Unfortunately, however, many people do not have an objective understanding of TCM, and many people have gone to extremes in their understanding of TCM. Those who believe in TCM tend to mystify or even mythologize it, believing that it is omnipotent and that it can eliminate all diseases without side effects. Those who are against TCM believe that there is no scientific basis for TCM theory, no rigorous clinical trials, and even call it pseudoscience. In fact, these are not objective. TCM is an empirical discipline, in which a distinctive theoretical system is summarized and in turn guides clinical practice. The cycle from the particular to the general and then to the particular is a scientific methodology. Likewise, TCM is not a myth, but only a therapy with its own limitations and strengths and weaknesses, and it is impossible to cure all diseases. Specifically, the common methods of Chinese medicine for the treatment of femoral head necrosis are either external or internal or both. For example, oral tonics and pills, external ointment fumigation and so on. In terms of treatment mechanism: 1, improve the blood supply to the femoral head, that is, the role of blood circulation and blood stasis, from this point of view, especially for early non-traumatic type is effective, but for late necrosis area blood circulation interruption is not very meaningful, through the drug to make the necrosis area to rebuild blood supply is unlikely. 2, pain relief, many drugs in Chinese medicine have pain-relieving effect, such as Yanhuoxiao, the mechanism of its pain-relieving components has been relatively clear, which is also the most direct way of Chinese medicine to play a curative effect, not much different from Western medicine. This function is the characteristic and advantage of Chinese medicine, many patients with osteonecrosis of the femoral head are accompanied by basic diseases and poor health condition, such as long-term alcohol consumption or use of hormones, through the identification of Chinese medicine treatment to improve their resistance to disease and promote osteogenesis for the treatment of osteonecrosis of the femoral head is beneficial, but this conditioning is limited and will not increase with the course of treatment. However, there is a limit to this kind of conditioning, and it will not increase with the course of treatment and the amount of medicine to cure. In summary, we can think of Chinese medicine as a way to treat osteonecrosis of the femoral head is possible to try to use, but to use early with scientific and reasonable, to dialectical treatment of a thousand people must be undesirable, in addition can not be used for years and months, when its efficacy to play out the efficacy to reach the extreme is that, and then only the accumulation of side effects. Especially for late collapse and then use will be harmful.
