The general public does not know much about artificial joints, and often think that during the operation, all joints will be removed and stainless steel joints will be installed, and the limbs will be like robots after the operation, which is hard and unnatural. In fact, artificial joint replacement is only to remove the worn and damaged joint surfaces, and then implant the artificial joints to restore the normal smooth joint surfaces, just like installing dental braces. It can be said to be one of the greatest breakthroughs in orthopedic surgery in this century. At present, it has been applied to the treatment of shoulder joint, elbow joint. It has been used to treat shoulder, elbow, wrist, interphalangeal joints, hip, knee and ankle joints, etc., but artificial hip and knee joint replacement is the most common. The design and material of artificial joints are the result of the continuous efforts of biomechanics experts, materials engineers and orthopedic surgeons. It is mostly made of metal and high-density plastic material according to the structure, shape and function of human joints. In order to make the joints and bones close together and not easy to loosen in the future, bone cement can be used to fix it or use the holes on the artificial joints to let the bones grow in (i.e., bio-type joints). Joint replacement surgery has been developed for more than a hundred years. Both the medical level of the doctors and the craftsmanship of the prosthesis have changed day by day, and joint replacement is being used more and more in the clinic, and more and more people are beginning to undergo this kind of surgery. First of all, when your loved one is told to undergo this type of surgery, one of the first questions you will consider is: should they have a joint replacement? Again, this is a question for your doctor to consider. Artificial total hip replacement is mainly used for patients over the age of 65 who have hip pain that cannot be effectively relieved by conservative treatments, to relieve pain and improve hip function. For example: rheumatoid arthritis in the late stage (hip joint limitation is obvious), osteoarthritis, ischemic necrosis of the femoral head in the late stage and fracture of the femoral neck does not heal (fracture of the femoral neck displacement is obvious or older), ankylosing spondylitis, congenital hip dysplasia, etc.; Artificial total knee arthroplasty don’t mainly used for knee arthritis (hemophilia, osteoarthritis, systemic lupus erythematosus, neurogenic arthritis, rheumatoid etc). Rheumatoid arthritis, etc.). The original purpose of joint replacement is to solve the patient’s pain and improve the patient’s quality of life. The first thing you should consider when choosing an arthroplasty is the same, for example, we have encountered this situation many times in the clinic: an elderly patient, 72 years old, femoral neck fracture, X-ray shows that the displacement of the broken end of the more obvious, mild osteoporosis; the physical condition is still good. The patient could have chosen arthroplasty, but the family approached us 6 months after the operation and asked for arthroplasty after the cut-and-replace internal fixation. Review X-ray showed that the fracture was not healed, and osteoporosis was obviously aggravated, and there were sores in the sacrococcygeal area, and there were scattered wet woven mats in the lungs, and the family was very thankful and regretted that arthroplasty was not performed after the fracture. This is one of the advantages of arthroplasty, which enables the patient to regain joint function at an early stage and eliminate pain. Of course, in our clinic, we have also seen arthroplasty performed at the age of 40, so we cannot help but ask whether it is better to perform internal fixation first. Obviously, the patient and his family did not grasp this problem when they chose. They only see the advantage of early recovery of joint function after surgery, but ignore the disadvantage of needing replacement surgery after 20 years. Therefore, when you encounter this kind of problem, you should also ask yourself whether you should be sued for joint replacement surgery, and listen to the professional doctor’s advice. Secondly, although the level of joint replacement surgeons is getting higher and higher and their grasp of details is getting better and better, most of the patients undergoing joint replacement surgery are on average over 60 years old, and most of these patients have high blood sugar, high blood fat, high blood pressure and other disorders, so whether or not the patient’s physical condition is able to withstand the surgery, and whether or not the patient can pass through the surgery and the perioperative period of the joint replacement surgery smoothly, is another issue. Patients and their families undergoing joint replacement surgery come here to improve their quality of life. If the surgery is unsuccessful, or if there are any problems in the perioperative period, how can we talk about the quality of the surgery? For example, when an elderly patient with a history of old cerebral infarction, older, just admitted to the hospital with coronary artery disease, electrocardiogram shows T wave flattening, at this time we will tell ourselves to first ask the relevant departments to consult, try to exclude the operation of the hidden dangers, the operation may cause the lowest possible harm, do not blindly seek speed, the operation as far as possible to do a little bit smaller, a little bit more conservative, the physical basis of the conditioning of a little bit better; the family members of the patient should also consider this issue, do not once hospitalized in a joint replacement operation, the patient’s family members should also consider this issue. To consider this issue, do not think of immediately doing surgery as soon as hospitalized, to choose professional hospitals, professional doctors, professional team to protect your family. Another issue that needs to be weighed is the question of the effect of the surgery: whether the effect of the surgery can satisfy the patient and his family. Sick people usually have a general idea, especially Chinese people, always think that as long as they enter the hospital and have surgery, their diseases and problems will be solved, this idea is very one-sided. Arthroplasty can certainly solve your problems, but a prosthesis is still a prosthesis, and the results cannot be 100% reliable. This requires the surgeon to conduct a thorough evaluation and careful examination before performing the surgery on the patient. After surgery, patients should not think that everything will be fine, but should follow the doctor’s instructions and practice actively. Early recovery. Only through the positive efforts of doctors and patients can we receive satisfactory results. The above three issues are not only for orthopedic surgeons engaged in joint replacement to face and think seriously, but also for patients and their families to consider. To solve the pain of the patient, minimize the risk of surgery, and receive satisfactory results is easy to say, but not so simple in practice, of course, also need the cooperation of the family, I believe that professional orthopaedic joints team can help you to solve these problems.
