Chinese people get together to socialize, quite a lot of attention to the human condition, wine is always a party of old friends, the depths of love a mouthful of boredom, do not drink do not give face to others, drink more injuries to the body, in the many cheer (cheers) sound, unknowingly, a few cups have been under the belly. Ordinary people so, doctors can not be exempted from the “common”. Anything, pay attention to a moderate amount. Usually occasionally drink a few small cups, soothe the mood, talk about a quality of life, entertainment and leisure a hand is not bad. However, if excessive alcohol consumption, it is easy to induce necrosis of the femoral head.” Shi Zhanjun pointed out. Some data show that adults cumulative consumption of 150 L of pure alcohol (cumulative weekly alcohol consumption of 400 mL) easy to cause necrosis of the femoral head. In China, the most common conditions for replacement of artificial hip joints are osteonecrosis of the femoral head and osteoarthritis in adults, and osteonecrosis of the femoral head occurs more often in male patients. Long-term heavy drinking can cause the accumulation of alcohol in the body, resulting in higher blood lipids, more and more viscous blood, slowing down the blood flow, blood vessel blockage, resulting in osteonecrosis. Most patients with osteonecrosis of the femoral head are already in a more serious condition when they are found. Because the early symptoms of the disease are not obvious, the pain is relatively mild and does not have a great impact on life. So many people think it is just a sprain and do not go to the hospital for examination. Even if they do get checked, early X-rays can’t detect the problem.” Magnetic resonance imaging is now an important tool that can detect necrosis of the femoral head at an early stage. It is therefore recommended that those who have been drinking alcohol for a long time, as well as those who have had traumatic injuries, who feel unexplained hip pain, are advised to go to the hospital to find out the cause. Quality of life is most important, and the age of surgery is not a big issue. The optimal age for joint replacement is 60-65 years old. From the point of view of artificial joint life and human life expectancy, it is more appropriate to replace the artificial joint after 60 years old, and people who are too young to replace the artificial joint may need to have another surgery in their later years to replace the “obsolete” artificial joint. However, does this mean that young people should not have joint replacement surgery? This is a matter of personal philosophy. You can’t wait until you are old to care about your quality of life. For example, artificial joints can be used in the body for 25-30 years (90% of patients). If a young man in his 20s suffers from ankylosing spondylitis and needs to have a joint replacement, should he really have to endure all kinds of pain and inconvenience until he is 60 years old because of a possible surgery in a few decades? For young people in their 20s, it is unrealistic to wait until they are old to think about improving their quality of life if it is not good when they are young. Although it is best to wait until age 60 for surgery, passive waiting is not the best strategy. In addition, nowadays, the surgical technology and the quality of artificial joints are constantly improving, and the service life is constantly prolonging. For young patients, if they use suitable artificial joints such as ceramic friction joints, they may not need to undergo surgery again in their lifetime, so why not cherish and live a good life in their younger years first. For the elderly, “Don’t think that spending money on joint replacement is too much of a burden to your family. In fact, it is the biggest burden to your family in your life. Being able to keep your family from having to worry about your health is the only way to make them feel better about their work. As a matter of fact, when it comes to the question of whether or not to opt for surgery, the doctor will first consider the needs of the patient. If the patient’s goal is simply painless, then we can consider not to do the surgery, the patient just stay in bed and do not move the joints will not be too painful, but if you want a high quality of life, want not to drag the family or even continue to contribute to the family such as buying groceries and washing clothes, or will recommend surgery. This is the ultimate goal of surgery: to reduce pain and improve quality of life. According to Shi Zhanjun introduction, now basically can do painless surgery, pre-operative hyperalgesia, can avoid central nervous over-excitement, significantly reduce or even eliminate the central sensitization after peripheral tissue injury, post-operative analgesic dosage can also be reduced. Whether it’s hip or knee replacement surgery, patients can generally get off the floor and practice walking within 48 hours after surgery. “Nowadays, there are basically no patients complaining that they can’t tolerate the pain of surgery, but going back ten years, this was still the case a lot. Knee joint health care to lose weight, exercise way to pay attention to osteoarthritis of the knee joint is most common in female elderly patients, talk about how to protect the knee joint, prevent joint problems, Shi Zhanjun said, a very important point is to lose weight. A person’s own weight of 80 pounds, grow to 120 pounds, that is equivalent to 40 pounds a day to walk on their backs, every day to do heavy physical activity, joint wear and tear can not be big. He confessed that he had lost weight before. “Once the heaviest time 85 kilograms, and finally reduced to the appearance of 75. Weight loss is not a one-day thing, is a long-term task, weight loss can not eat, do not eat absolutely not, of course, hungry to eat, fat is not reduced. Weight loss can not be separated from the movement, but, choose the appropriate way of exercise is very important. Less climbing more swimming more walking is the best way to exercise. Many people love to climb the mountain, but some data show that when going up and down the mountain, the knee joints of the weight was 3 times and 7 times the weight. Once met a patient, only about 40 years old, but the joint checkup is surprising, two knee joints wear and tear is very serious, the reason for this, the original patient is an avid climber, climbing as eating and sleeping, is a daily necessity. It is recommended that mountaineering enthusiasts, especially the elderly try to avoid steeper slopes and multiple steps, choose a slightly smoother road, climb slowly, but also hand-held wall or railing, or use a walking stick, such as feet in the same step and then take the next step.
