Lifespan of artificial femoral head

For some patients with femoral head necrosis, when the disease develops to a certain extent, they will go to the hospital for surgical treatment. The best way to treat femoral head necrosis is to replace the necrotic bone and use an artificial femoral head to maintain normal use of the bone. So, do you know how long the lifespan of an artificial femoral head is? In fact, generally speaking, the service life of artificial femoral heads is 15-20 years!

The service life of an artificial femoral head is about 20 years. Twenty years after replacement, the artificial prosthesis will be damaged, and a second operation will be required to replace the prosthesis. Of course, the specific time required for each person is different. This is related to the amount of activity after replacing the prosthesis, and whether trauma occurs again. Currently, the surgical technology for joint replacement is relatively mature and the success rate is relatively high. As long as there are no accidents, most replacements can be successful.

Artificial femoral head replacement is a commonly used surgical treatment for femoral head necrosis in Western medicine. It replaces the necrotic femoral head with an artificial femoral head prosthesis. It is suitable for people such as elderly patients with femoral head necrosis over 65 years old, patients with severe hip fractures, and other diseases. Artificial femoral heads have a certain service life in the human body. Patients who have undergone artificial femoral head replacement surgery need to undergo another femoral head replacement after 5-15 years. Some patients even have failed operations and need a second replacement shortly after the first operation.

The artificial femoral head is made of high-quality medical steel and has no self-repair ability. Therefore, the artificial femoral head needs special protection to keep the prosthesis alive in the patient's body for as long as possible. First of all, you should pay attention to daily lower limb movements, do not cross your legs, do not sit low, do not jump on one leg, avoid excessive weight bearing and too much physical labor, use crutches or canes when appropriate to reduce the wear of artificial joints. The debris produced by wear can cause bone dissolution or cause the prosthesis to loosen and sink; secondly, pay attention to eliminating inflammation in the body, and areas with chronic inflammation should be treated in time to avoid inducing joint infection; regular examinations should be performed after femoral head replacement, and should be reviewed at least once a year. Choose conservative treatment and try to avoid replacement. Patients with femoral head necrosis should try to avoid replacement surgery because replacement surgery has higher risks, is prone to complications such as postoperative infection, and has greater surgical trauma. Although patients have escaped from the necrosis, other problems caused by the surgery still follow the patients. Therefore, patients with femoral head necrosis should choose conservative treatment to cure or improve the disease.
