Wine culture is a major feature of China, and wine as a special cultural carrier, occupies a unique position in human interaction, has penetrated into every aspect of people’s lives, there are reports that the amount of liquor Chinese people can drink a year is about as big as a West Lake, so it can be seen that the consumption of liquor in China is large. ”A small drink is pleasant, a large drink hurts” many people are familiar with a truth, but where the harm of liquor, but not everyone understands, we once did a simple survey in the TV program, found that everyone for the stomach, liver, kidneys, etc. are more agreeable, and after drinking alcohol have a trick to stomach, liver, kidney relief, but there is a But there is a key part that is ignored by everyone – this is the hip joint. Similar to alcoholic liver, hip joint problems can occur under long-term alcohol consumption, and the probability of occurrence is increasing, and the proportion of the population is also increasing, outpatient clinics often see 30-40-year-old patients limping to the clinic because of hip pain, careful questioning often found that they either like to drink, three meals a day to pour their own drinks, or because of work and social business needs to exchange glasses, the result Work performance is up, but the hip joint problems, a careful investigation confirmed the diagnosis of alcohol hip – medical diagnosis of alcoholic femoral head necrosis. The hip joint is a large joint connecting the human pelvis and lower limbs, consisting of the femoral head and acetabulum, they are like an inverted pestle and mortar, with good weight-bearing and stability while moving, and the femoral head is the most vulnerable due to the peculiarities of its own anatomical structure: the blood supply of the femoral head itself, as shown above, is supplied by the branches of the thicker arteries and their endings, they are at the base of the femoral neck A ring of blood supply arteries is formed, and in the head it relies mainly on the fine branches emanating from this ring for nutrition, similar to the coronary arteries of the heart, and once a blockage is formed in them, it leads directly to ischemic necrosis in the area of blood supply innervation. After drinking a lot of alcohol, alcohol metabolism is mainly carried out in the liver, which causes fat to accumulate in the liver, forming a fatty liver and continuously releasing fat emboli into the blood, which are retained in the terminal small blood vessels and subchondral vascular beds, causing ischemia and necrosis of cartilage; at the same time, the process of alcohol metabolism produces acetaldehyde and other lipid peroxides, thus causing further damage to the endothelium of blood vessels and forming tiny emboli to block blood vessels; coupled with The direct cytotoxic effect of alcohol and its metabolites, alcohol consumption can also cause disorders of vitamin D metabolism, reduced metabolism of bone cells, reduced osteogenic capacity, osteoporosis, resulting in a high stress osteogenic response due to reduced local stress area, destruction of bone cells, microfractures under the cartilage, causing increased local intraosseous pressure and bleeding, leading to osteonecrosis. These changes result in the femoral head not receiving sufficient nutrient supply, and the chronic damage that occurs under weight bearing cannot be repaired in time, resulting in the collapse and deformation of femoral head necrosis over time. So what is the manifestation of alcoholic femoral head necrosis? In the early stage, it is a vague pain or soreness, especially when crossing the legs, and the pain can radiate to the inner thigh and knee joint, which is often mistaken for lumbar disc herniation or knee joint disease; as the condition gradually worsens, patients will find it difficult to squat, put on shoes or socks by themselves, and walk with a limp. As the condition gradually worsens, patients may find it difficult to squat, struggle to put on shoes or socks by themselves, and walk with limp. If the condition becomes more severe, the two legs may not be the same length and the patient may not be able to stand and walk. Therefore, those who have a long-term habit of drinking a lot of alcohol need to be vigilant and should go to a regular hospital as soon as the above situation occurs. X-rays and MRI can make a clear diagnosis, and MRI has a very good sensitivity for early lesions, which can help patients to get early treatment and avoid further severity of the disease. In the early stage of alcoholic femoral head necrosis, the progress of femoral head necrosis can be slowed down by abstaining from alcohol, supporting double crutches to reduce weight-bearing, and taking oral medications to promote microcirculation and osteonecrosis repair; and according to the characteristics of early femoral head appearance is still intact, simple internal cystic changes and sclerotic repair, the femoral head can be decompressed with bone grafting to open up the ischemic necrotic area in the femoral head and re-establish the blood supply. According to the experience of our joint center, about 70% – 80% of patients with early stage femoral head necrosis can obtain satisfactory results through this method, thus preserving their femoral head; however, if the shape of the femoral head is found to have changed and collapsed on X-ray, this situation belongs to the advanced stage of femoral head However, if the shape of the femoral head is found to have changed and collapsed on X-ray, this is an advanced stage of necrosis and the effect of head preservation treatment is often unsatisfactory. The fundamental solution to the problem is to obtain an artificial joint by means of joint replacement. ”Small drink is good, big drink is bad” how small is small: from the point of view of avoiding femoral head necrosis, we recommend that the total amount of liquor per day should not exceed 2 taels; for long-term drinking and hip pain, we recommend actively seeking medical attention. We wish you all a good health.
