Artificial Hip Replacement and Postoperative Rehabilitation Artificial hip replacement refers to the use of metal, polymer polyethylene, ceramics and other materials, according to the human body’s joint form, structure and function of the artificial joint prosthesis, implanted in the body through surgical techniques, to replace the function of the diseased joints, to achieve the purpose of relieving joint pain and restoring the function of the joints. Artificial joint replacement is one of the most successful orthopedic surgeries in the twentieth century, which has enabled countless patients suffering from end-stage bone and joint diseases to regain a normal life. Indications: 1, femoral neck fracture; 2, femoral head necrosis; 3, osteoarthritis; 4, rheumatoid arthritis; 5, congenital hip dysplasia; 6, ankylosing spondylitis; 7, hip tumors; 8, other rare diseases, such as: metabolic disorders, infectious diseases of the joints, traumatic arthritis and so on. Pre-operative preparation: Doctors will conduct a comprehensive pre-operative examination of the patient, including: physical examination, laboratory tests, a variety of auxiliary tests, etc., to comprehensively assess the patient’s physical condition in order to determine whether the patient is suitable for surgery, as well as to formulate a surgical plan, to reduce the chances of post-operative complications. At present, a good joint surgeon will complete the artificial joint replacement in about 1 hour to restore the patient’s hip function. Postoperative rehabilitation 1. Functional exercise On the first day after surgery, the patient should lie down flat, and should not use pillows within 6 hours. On the first postoperative day, the patient should lie flat, and should not use pillow within 6 hours. On the same day after operation, the patient can perform ankle joint active flexion and extension activities, which can promote the return of blood to the lower limbs, and reduce the chance of deep vein thrombosis. On the second postoperative day, the bed can be swung up to 30°, and active ankle flexion and extension exercises and isometric contraction of quadriceps muscle can be performed to maintain muscle tone. On the 3rd to 4th day after surgery, the bed can be swung up to 60°, and the patient can take the initiative to perform hip and knee flexion and extension exercises and straight leg raising exercises to increase the venous return and prevent the atrophy of quadriceps muscle. Note that hip flexion should be less than 70 degrees, and the lower limbs should not be inwardly retracted. After reviewing by film, you can go down to the ground under escort. One week after the operation, practice sitting to standing position, shift the center of gravity to the healthy side, support the bed with both hands, keep the affected leg abducted, slowly move the affected limb to the ground, and then move the healthy limb to the ground, sit on the edge of the bed. Then stand up with the support of the crutches and practice walking. 2, specific exercise methods: (1) hip extension: A, tighten the gluteal muscles, slightly do hip elevation, hold for five minutes. B, straighten the knee, joint backward extension of the lower limb. (2) Hip flexion: A, lying down, to the hip agitation heel, pay attention to hip flexion is not greater than 90 degrees. B, standing, pay attention to hip flexion is not greater than 90 degrees. (3) Knee extension: Lift one leg about 15 centimeters, hold for 5 seconds, then change leg, repeat 10 times. (4) Hip abduction: A. Keep the toes up in bed, straighten the lower limb, and spread the lower limb outward. B. Stand with the lower limb straight, spread the lower limb outward, hold for 5 seconds, and repeat 10 times. (5) Correct posture for getting out of bed Move the affected limb close to the edge of the bed Lower leg down slowly Try not to put your weight on the affected side The healthy side holds the walker with its hand, and the affected side holds the edge of the bed with its hand, and stand up slowly. (6) Correct posture with crutches Standing first out of the left crutch, step right foot out of the right crutch l step left foot V. Preventing complications 1, prevention of dislocation. It should be especially emphasized within six months after surgery. (1) Hip flexion not more than 90 degrees: including sitting up with the body bent not more than 90 degrees (do not sit on a short stool, toilet, sofa, etc., not more than 90 degrees when bending over). (2) Do not excessively retract the affected limb: Do not cross your legs, do not cross the affected limb to the opposite side when standing, and when sleeping on the side, a thick pillow must be sandwiched between the two legs. (3) Do not rotate the affected limb externally: do not sit cross-legged on the bed. (2) Prevention of venous thrombosis: starting functional exercise as early as possible is the fundamental measure to prevent venous thrombosis. 3.Prevent lung infection: ask the patient to sit up and encourage coughing to prevent pneumonia. After joint replacement, any infection in the whole body must be actively treated to prevent the bacteria from transferring to the joints through the bloodstream and causing joint infections. Postoperative follow-up 1 month, 3 months, 6 months, 12 months after the operation, and once a year thereafter, the patient should come to the hospital for routine follow-up examination and X-ray filming. The purpose of the follow-up visit is to guide the patient to further rehabilitation training in order to achieve the best results of the surgery. Please note that each patient has his/her own special circumstances and conditions, and the specific methods of functional exercises should be carried out under the guidance of your surgeon, the above is for reference only.
