What is the purpose of artificial hip replacement? ① To relieve pain; ② To restore and improve the motion function of the joint; ③ To correct the deformity; 3, what are the contraindications for hip replacement surgery ① Recent and current infection in the hip joint, and infection in the remote area; ② Unstable medical condition, such as the underlying disease is too serious to tolerate the replacement surgery; 4, what should be prepared for the preoperative artificial hip joint replacement surgery? ① should be under the guidance of the doctor the correct use of crutches, strengthen the quadriceps isometric muscle contraction, ankle flexion and extension exercises, to master the correct method of effective coughing and phlegm expectoration; ② preoperative preparation for the examination, skin preparation, the treatment of systemic concomitant diseases, prevention of colds, smoking cessation, practicing bedtime urination and defecation; ③ diet light, easy to digest to ensure that the postoperative urinary and faecal fluids, fasting before the operation, to prevent the operation of vomitus accidentally inhalation (c) Eat a light diet, easy to digest, to ensure smooth urination and defecation after surgery. 5, the advantages and disadvantages of artificial hip joint ① Advantages: a: surgical technology is mature; b: shorter surgical treatment period, about one month or so; c: basically all the joint pain can be removed. ② disadvantages: a running, stool mountain such sports have an impact; b after surgery should be avoided to sit on a short stool and squatting completely; c after 10-15 years after surgery, the bone and artificial joints between the possible loosening of the proportion of the number of the need for replacement of about 5% -10%; d artificial joint infection is very difficult to treat. 1% of the people caused by the infection after surgery to prolong the treatment time, or even had to remove the artificial joints, after infection control, the joints again. After the infection is controlled, the joint is replaced. Replacement of the joint infection rate is higher than the first surgery; e wear and tear and loosening of the artificial joint is also the cause of postoperative pain, surgical failure; f expensive; 6, the main process of hospitalization ① hospitalization day and the next day: hospitalization procedures, bed arrangements, the doctor to ask about the medical history and checkups, pre-surgery routine tests and inspections. ② pre-surgery day: pre-surgical conversation and sign the consent for surgery and other medical documents, drug allergy skin test, skin preparation, blood preparation procedures. ③ day of surgery: fasting water, catheterization, infusion, surgery. After surgery, the patient should be given an infusion tube, urinary catheter and drainage tube. ④ After surgery: remove the stitches in 10-12 days, gradually enhance the functional exercise, generally around 1 week to go down on crutches. 7, the duration of use and efficacy of artificial hip joint Hip joint is an important joint, which has various functions such as walking, running, jumping, squatting and so on. Once the hip joint is diseased, the cartilage of the joint will be destroyed, and the original smooth surface like a mirror will become a rough or even defective surface, which will further deform the bone. As a result, you will feel pain, have difficulty walking, have limited movement and limp. When the above diseases have progressed to a certain level and the joint has been destroyed, surgery is needed. An artificial hip joint is used to replace the damaged joint to restore walking and other functions. The biggest benefit of artificial joint surgery is that it can eliminate joint pain after surgery, greatly improve the function of the joint, and improve the quality of life of the patient, so that he or she can work and live well during his or her lifetime. Successful artificial joint replacement surgery allows you to live pain-free and fulfill your daily activities, and no other treatment can achieve the same results for a damaged hip. At present, more and more patients are happy to accept the suggestion of artificial joint surgery. 8, the service life of the artificial hip joint: mainly determined by two points, one is the wear and tear of the joint, and the other is the loosening of the prosthesis caused by wear particles. The strength and wear resistance of the artificial hip joint material can generally satisfy the patient for more than 20 years. Nowadays, twenty years after the placement of artificial joints, more than 95% of them can continue to be used. Of course, the service life of the artificial joint is also related to many factors, such as the patient’s exercise, the choice of artificial prosthesis, the surgeon’s surgical techniques and their own conditions. Post-operative review: three months after discharge from the hospital, we should go to the hospital for review and take X-ray to know whether the position and stability of the joint prosthesis are good or not. After six months of operation, you will be rechecked again, and then you will have to take X-rays every year. If there is any discomfort, such as redness, swelling, pain or difficulty in moving the joints, or if the joints are injured due to accidents, you should go to the hospital for examination in a timely manner. 10.How should I perform rehabilitation exercises after surgery? ① the day after surgery can be centripetal massage of the affected limbs from the dorsum of the foot, ankle active, passive extension and flexion exercises; ② 2 to 3 days after surgery, after removing the drainage tube can be hip, knee extension and rotation exercises, flexion and extension exercises from the passive to the active transition; ③ 4 days to 2 weeks after surgery, the patient’s physical strength has been recovered, and gradually began to sit from lying down, sitting, from sitting to stand, from standing to walk the training (the process) The patient’s physical strength has recovered, and gradually start training from lying down to sitting, from standing to standing, from standing to walking (in this process, attention should be paid to prevent falling); ④ In the third postoperative week, the patient gradually regained the ability of weight-bearing, and strengthened the training of gait; ⑤ In the fourth to sixth postoperative weeks, the range of motion of the hip joint of the affected side was gradually improved, and the ability of weight-bearing of the affected hip was increased, so as to make the function of the artificial hip joint close to normal; ⑥ In the seventh to twelfth postoperative weeks, it was mainly to improve the overall strength of the muscles, and continue to practise the use of crutches to carry out walking training. In short, the rehabilitation training must follow the principles of early, middle and late, individualization and gradual progress. 11.What should be paid attention to after going home with artificial hip replacement surgery? ① functional exercise should be gradual, first help the crutches down to the ground, and then gradually abandon the crutches to walk; ② for your seat, toilet and stairs to install reliable handrails; ③ for your seat to prepare a comfortable cushion, and safe backrest and armrests, and prepare a footstool to facilitate the rest of your limbs; ④ toilet elevated; ⑤ shower room to prepare reliable handrails and chairs; ⑥ clear your activities at home in the area of all possible objects that may cause you to fall, such as ⑥ Remove all objects in the area of your home that could cause you to fall, such as removable rugs and telephone cords.
