I. Which cases are suitable for hip joint replacement surgery?
(1) Various inflammatory arthritis of the hip joint, including primary or secondary osteoarthritis, traumatic arthritis, rheumatoid arthritis, hemophilic arthritis, Charcot arthritis, etc;
(2) Femoral head necrosis;
(3) congenital dislocation or subluxation of the hip joint and acetabular dysplasia;
(4) Hip fusion or pseudarthrosis;
(5) Periprosthetic tumors;
(6) resting infectious arthritis (including tuberculosis);
(7) failed repair after hip reconstruction surgery.
Second, which cases are contraindicated for hip replacement surgery?
(1) Recent and current infection of the hip joint, infection of the distant part;
(2) Unstable medical condition.
Third, the advantages and disadvantages of artificial hip joint
The advantages are.
(1) The surgical technique is mature.
(2) The surgical treatment period is relatively short, about one month.
(3) The joint pain can basically be completely removed.
The disadvantages are
(1) It has an effect on sports such as running and benching hills.
(2) Sitting on a low stool and squatting completely should be avoided after surgery.
(3) After 10-15 years after the surgery, the bone and the artificial joint may loosen, and the percentage of replacement is about 5-10%.
(4) It is very difficult to treat infections in artificial joints. 1% of people have infections after surgery, which require prolonged treatment or even removal of the artificial joint, and joint replacement after the infection is controlled. The rate of infection in the resurfaced joint is higher than in the first surgery.
(5) Wear and loosening of the artificial joint is also a cause of post-operative pain and surgical failure.
(6) The price is more expensive.
Fourth, how to choose a good artificial hip joint?
When a patient decides to use artificial joint replacement treatment, a question is often raised: what kind of artificial joint is the best artificial joint? It should be said that different patients should choose different artificial joints. Artificial joint prosthesis has very strict requirements on its design, surface treatment, material selection, manufacturing process and packaging; it also needs sufficient clinical practice to confirm the effect of a certain artificial joint. At present, the artificial hip joint has become a very mature artificial joint, both in terms of the prosthesis itself and in terms of surgical techniques. The artificial hip joint has been widely used in clinical practice and has achieved good clinical results. The choice of artificial hip prosthesis is very different from the choice of other commodities, because once the artificial hip prosthesis is placed in the human body, it is not easy to “replace”, even if the “replacement” cost is also quite large, it can not be measured with money. Therefore, the choice of a good artificial joint should be made carefully under the guidance of experts.
V. The main process of inpatient treatment
The day of hospitalization and the next day: hospitalization procedures, bed arrangement, medical history and physical examination by doctors, routine tests and examinations before surgery.
The day before surgery: pre-surgery conversation and signing of medical documents such as surgery consent form, drug allergy skin test, skin preparation and blood preparation procedures.
On the day of surgery: fasting, catheterization, infusion, and surgery. After surgery, we will leave the infusion tube, urinary catheter and bleeding drainage tube.
After surgery: 10-12 days to remove the stitches, gradually enhance functional exercise, generally in about 1 week crutches to the ground.
VI. Post-operative examination
Three months after discharge from the hospital to review, take X-rays, to understand the position of the joint prosthesis and stability is good. Six months after the operation and then once again, and then every year to take the film examination. In case of discomfort, such as redness, swelling, pain or difficulty in moving the joint, or if the joint is injured due to an accident, go to the hospital for examination in time.
VII. Duration and efficacy of the artificial hip joint
The hip joint is an important joint, which has various functions such as walking, running, jumping and squatting. Once the hip joint is diseased, the cartilage of the joint will be destroyed, and the surface will become rough or even defective from the original smooth surface like a mirror, and furthermore the bone will be deformed. As a result, you will feel pain, have difficulty walking, limited movement, and limp. When the disease progresses to a certain level and the joint is destroyed, surgery is required. An artificial hip joint is used to replace the damaged joint to restore walking and other functions. The greatest benefit of artificial joint surgery is that it can eliminate joint pain after surgery, greatly improve the function of the joint, and improve the patient’s quality of life so that he or she can work and live well during his or her lifetime. Successful arthroplasty allows you to live a pain-free life and perform daily activities that no other treatment can achieve for a damaged hip joint. Nowadays, more and more patients are willing to accept the suggestion of artificial joint surgery. The longevity of the artificial hip joint is determined by two factors: the wear and tear of the joint and the loosening of the prosthesis due to wear particles. The strength and wear resistance of the artificial hip material can generally satisfy the patient for more than 20 years. Nowadays, the artificial joint can be used for more than 95 percent of the twenty years. Of course, the service life of the artificial joint is also related to many factors, such as the amount of movement of the patient, the choice of artificial prosthesis, the surgeon’s surgical technique and their own conditions.
VIII. Treatment of artificial hip joint after loosening or infection
Once the artificial hip joint becomes infected or aseptically loose, joint revision surgery is required. There are specially designed hip prosthesis and surgical instruments for the revision surgery. The revision surgery is more complex than the initial surgery and may require bone grafting, a different type of joint prosthesis, or the use of a special prosthesis. After revision surgery, the majority of patients can achieve a satisfactory outcome.
IX. Protection after artificial hip replacement surgery
After the artificial hip replacement, you need to develop good habits of life and activities to maintain the stability of the joint, and learn some simple rehabilitation knowledge and carry out joint rehabilitation exercises. Pay attention to the prevention and control of infections, and actively treat infections such as tonsillitis, skin infections, ringworm, etc. After surgery, you can do exercises such as cycling, walking, dancing and swimming, but strenuous exercises such as running and jumping, as well as long-distance walking and climbing are not encouraged. In addition, some hospitals provide patients with post-operative rehabilitation manuals for their reference.
X. Rehabilitation after hip replacement
Rehabilitation exercises are crucial to the success of total hip replacement surgery. Isometric contraction of the muscles of the affected limb can be performed after surgery. If the joint position and fixation are good, rehabilitation exercises can be started under the guidance of the doctor and the rehabilitation teacher, even after complete rehabilitation and discharge, regular rehabilitation exercises are generally required.
