Femoral head necrosis is a pathological process of aseptic inflammation and necrosis of the femoral head due to certain causes, characterized by pain, claudication and functional impairment. The disease is mostly seen in middle-aged and young people, with progressive aggravation and late manifestation of femoral head collapse and loss of joint function, resulting in a very high disability rate and seriously affecting patients’ ability to take care of themselves. Since 2005, we have sent Deputy Director Yang Bin to Beijing to study the treatment of femoral head necrosis and established a collaborative relationship with the Chinese Academy of Traditional Chinese Medicine, who sent professors to guide us. We have established the “Bone Disease and Femoral Head Necrosis Treatment Center”, which has achieved great success in combining Chinese and Western medicine, and held an inauguration ceremony and academic meeting in our hospital. In 2008, our hospital was the collaborating hospital of the “Eleventh Five-Year Plan” National Science and Technology Support Program “Chinese Medicine Treatment Research on Femoral Head Necrosis”, which has enhanced the level and reputation of our hospital in treating bone diseases, especially femoral head necrosis. Second, the incidence of necrosis of the femoral head and the source of disease in our city According to statistics, the world is currently suffering from this disease about 30 million people, Japan has 2500 ~ 3000 new cases each year, while the United States is up to 15 ~ 20,000, China’s large population base, medical conditions are not perfect, national statistics show that there are more than 7 million such patients, about 10 ~ 20,000 new patients each year, after SARS in 2003 The incidence of 30% to 50% of osteonecrosis not only makes this morbidity population suddenly increase, but also makes the treatment of femoral head necrosis become an urgent social problem. According to incomplete statistics, there are many patients with decompression sickness caused by diving in the coastal area of Rizhao, and there are more than 100 patients with decompression sickness caused by diving in the village of Wangjia in Tao Luo. In addition, there are many patients with alcoholic, hormonal femoral head necrosis and traumatic femoral head necrosis. Third, the development of femoral head necrosis (a) At present, we can independently carry out early and middle stage femoral head necrosis “head preservation” treatment: drilling decompression; interventional treatment, a series of Chinese medicine dialectical treatment; lesion removal bone flap transfer; lesion removal compression bone grafting; drilling decompression stem cell transplantation; bone flap transfer tantalum rod up internal fixation, so that the middle and late stage Femoral head necrosis patients timely surgical intervention, delay or avoid femoral head necrosis arthroplasty. At present, more than 200 cases of such patients have been successfully treated in the city’s Chinese medicine hospital, and nationally renowned professors of femoral head necrosis regularly come to our hospital for consultation and technical guidance. This treatment method is at the leading level in China. (b) At present, we are able to carry out total hip replacement for advanced femoral head necrosis independently. (3) Academic exchange of femoral head (1) In 2005, we established a collaborative relationship with the Chinese Academy of Traditional Chinese Medicine and set up the “Bone Disease and Femoral Head Necrosis Treatment Center”, which has achieved great success in combining Chinese and Western medicine. (2) On March 27, 2009, the kick-off meeting of the Rizhao Station of the “Eleventh Five-Year Plan” National Science and Technology Support Program on “Chinese Medicine Treatment of Femoral Head Necrosis” was held at the Municipal Hospital of Traditional Chinese Medicine, which invited the members of the National Femoral Head Necrosis Committee of the Orthopedic and Traumatology Branch of the Chinese Society of Traditional Chinese Medicine and the “Femoral Head Necrosis” Committee of the Beijing Health Bureau. Professor Chen Weiheng, member of the National Femoral Head Necrosis Committee of the Orthopedic and Traumatology Branch of the Chinese Academy of Traditional Chinese Medicine and head of the Chinese Medicine Group of the Beijing Municipal Health Bureau, was invited to the meeting. During the meeting, Prof. Chen held a seminar and gave free medical consultation and on-site technical guidance to some patients with femoral head necrosis, and provided patients with “hip preservation” treatment, including TCM intervention, focal removal and compression bone grafting, stem cell transplantation and tantalum rod fixation, which enabled some patients to avoid the pain of joint replacement surgery.
