Femoral head necrosis, also known as ischemic necrosis of the femoral head or aseptic necrosis of the femoral head, is a disease caused by ischemia of the femoral head and osteoclastic necrosis, which leads to changes in bone structure and mechanical function, causing hip pain and functional impairment. Femoral head necrosis disease process progresses quickly, most patients after the occurrence of femoral head necrosis about 2 years after the femoral head collapse, so the femoral head necrosis disability rate is high, seriously reducing the quality of life, causing femoral head necrosis is a variety of reasons, but the most important and common are the following three main reasons: First, long-term use of hormones during the last 20 years hormonal femoral head necrosis accounted for all femoral head necrosis 46.03%, so this kind of femoral head necrosis is extremely common in the clinic. There are some patients suffering from immune diseases, such as systemic lupus erythematosus, rheumatoid, dry syndrome, etc. In some cases, hormones must be applied in order to control the condition, and the use of hormones is inevitable. However, some friends blindly believe in the so-called “prescriptions” or “ancestral secret recipes” on the street, which may contain hormones, so they may be able to temporarily relieve the symptoms after using them, but the incorrect dosage and usage of hormones may lead to the problem of femoral head necrosis. Therefore, “hormones” are fiercer than tigers, so when you use hormones or hormone-containing drugs, you must apply them under the guidance of a doctor, and of course, you should not trust the so-called “prescriptions” or “secret recipes”. Ancestral secret recipe”. Second, long-term alcoholism alcoholic femoral head necrosis in our hospital accounts for 15.4% of all femoral head necrosis, the proportion is also very large. Moderate drinking can promote blood circulation, can relieve mental tension, reduce stress-related diseases, especially cardiovascular disease, but if long-term, heavy alcohol abuse can be extremely harmful to our health, such as fatty liver, pancreatitis, memory loss, etc., and of course, we talk about today’s femoral head necrosis, alcohol leads to increased blood viscosity caused by bone microcirculatory disorders and necrosis of the femoral head Alcohol is a double-edged sword. Alcohol is a double-edged sword, we must grasp the “degree”, so for the sake of our health, we suggest that alcoholic friends better quit drinking, and we suggest that the total amount of liquor should not exceed 2 taels per day if there are really difficulties. Third, hip trauma, the most common of which is femoral neck fracture Fracture of the femoral neck can directly affect the local blood supply of the femoral head, resulting in femoral head necrosis. Femoral head necrosis occurs in 1M3 of patients with femoral neck fracture. Patients with femoral neck fracture must go to a regular hospital for treatment in time, without delay, so as not to delay the best time for fracture repositioning. Especially for those over 60 years old, if a fall occurs and there is discomfort in the hip, it is very necessary to go to a nearby hospital to have a hip radiograph so as not to delay the diagnosis and miss the best treatment window. In order to avoid the occurrence of alcoholic femoral head necrosis, we suggest that friends try to avoid the habit of long-term heavy drinking, and for those who really have difficulties, we suggest that the total amount of liquor should not exceed 2 taels per day; for long-term drinking and hip pain, we suggest actively seeking medical attention.
