Artificial hip joint replacement is a common orthopedic surgery that uses modern biological materials to make an artificial joint similar to the physiological form of the human body to replace the function of the human hip joint. Awareness of the normal hip joint: symptoms of hip arthrosis: 1, hip pain 2, hip swelling, deformation 3, limb movement is restricted 4, walking difficulties, limp I, artificial joint replacement includes which parts: acetabular cup, acetabular liner, femoral head, femoral stem composition. Second, which cases are suitable for hip replacement surgery? (a) Old age degenerative hip disease. (2) Fracture of the femoral neck and traumatic arthritis. (3) Aseptic necrosis of the femoral head for various reasons. (D) Advanced rheumatoid arthritis. (E) Ankylosing spondylitis combined with bilateral hip ankylosis. (F) Congenital acetabular dysplasia. (vii) Various benign or low-grade malignant tumors. Third, what problems are likely to occur after artificial hip replacement? The common problems after artificial total hip replacement are loosening of the replaced metal prosthesis, joint infection, dislocation of the artificial femoral head and femoral fracture. The main reasons for the loosening of the metal prosthesis are the quality of the metal itself and the surgical operation. Loosening often occurs 5 years after the operation. Fourth, what are the problems to be noted after the artificial total hip arthroplasty? In the early postoperative period, the main concern is to prevent infection, so pay attention to personal hygiene, including sputum removal and diligent mouth rinsing. The next thing is to decide the time to sit up and get down according to the doctor’s advice. After discharge from the hospital, you should pay attention to actively exercise the function of the lower limbs and exercise the muscle strength of the lower limbs in a gradual manner. V. Functional exercise after artificial total hip replacement 1. In order to maintain the position of the new hip joint, a pillow should be placed between the legs after surgery to open the legs for six weeks. 2. On the day after surgery, the nursing staff should assist and guide you to turn over at least once every 2 hours with the pillow. 3. Practice flat leg raising exercise as early as possible when lying in bed to strengthen the quadriceps muscle. 4. Do not pull or twist the drainage tube at the wound to keep it open, the nursing staff will assist and instruct you how to squeeze it. 5. After surgery, follow the instructions and assistance of the nursing staff to get out of bed. 6. When moving around within six weeks after surgery, the affected limb should not be bent at an angle of 90 degrees to the body and remember the following five points: (1) Sit with the knee at the same height as the hip. (2) Sit with your legs 8-15 cm apart. (3) Do not sit in a chair without armrests, which can safely help you stand up from a sitting position. (4) Do not cross your legs when sitting or lying down. (5) Do not bend at the waist. Pelvic exercise, leg suspension exercise, leg straightening and lifting exercise, lateral leg extension exercise, knee abduction exercise, heel extension exercise, knee suspension exercise, hip abduction exercise. 7. Use crutches, walkers or canes to reduce the weight on the hip as directed by the health care provider. 8. In order to limit the bending of the hip, you can buy elevated toilets and long handles to facilitate picking up objects on the floor or other things that can be removed by yourself. 9. After the stitches are removed, it is more convenient to take a shower when bathing. 10. You can gradually resume activities, you can play golf, swimming and other upper body activities, but do not engage in more strenuous sports, such as tennis, skiing, etc. 11. Before having minor surgery or going to the dentist, remember to remind the doctor that you have an implant on your body, because the application of antibiotics can prevent the infection of the implant. 12. When hip pain worsens, leg swelling, discharge, chest pain or shortness of breath, you should contact your physician immediately. 13. Return to the outpatient clinic as instructed by the health care provider, and you may ask the physician for further advice. 14. Positions that can and cannot be used: Appropriate positions: To pick up objects on the ground, please bend the knee of the healthy limb and extend the affected leg backwards To put on socks and pick up objects at the early stage after surgery, temporarily ask a family member to do it for you or use an aid. When sitting down, the affected leg should be stretched forward, and the chair should be high enough, preferably with armrests. When standing or sitting down, the legs should be spread apart. “Two O legs” Older people fall and fracture their hip joints, what should they do? In the past, they had to stay in bed for a few months to let the bones grow slowly, but with the development of medical technology, broken joints can now be replaced like broken car parts, and some 70- and 80-year-olds can have the right to walk again through artificial joint replacement surgery. However, the replacement joint is after all a foreign body, so there is a lot to learn about how to adapt the body to this “new partner” after surgery.
