I.What is ceramic heads?
The main materials of artificial hip joints refer to the materials of the artificial femoral head and the acetabulum. The appearance is similar to the ball and bowl used to mash garlic. The ball refers to the femoral head and the concave part is the acetabulum. When the joint moves, the ball will slide inside the acetabulum, and this movement will inevitably cause friction. In order to reduce the wear of the ball head and increase the service life of the artificial joint on the basis of the original metal head, the ceramic head came into being.
Metal joints were created earlier, and the surgical plan of metal plus metal joints has basically been eliminated. Because the wear rate of metal on plastic joints is about 1,000 times higher than that of ceramic plus ceramic, this leads to the problem of short service life of metal heads.
In addition, ceramic materials produce less debris during use and will not release metal ions into the body like metal joints. It prevents metal ions from entering the blood, urine and other body organs, and avoids adverse reactions between cells and body tissues in the body. The debris generated by the friction of metal heads is extremely harmful to women of childbearing age, people with kidney disease and people with metal allergies.
II.What are the excellencies of ceramic heads over metal heads?
In addition, the ceramics used in hip replacement surgery are not ceramics in our traditional sense. As mentioned above, the fourth generation of ceramics uses alumina ceramics and zirconium oxide ceramics. Its hardness is second only to diamond, which can ensure that the joint surface is always smooth and difficult to wear. Therefore, the service life of ceramic heads can theoretically reach more than 40 years.
III.Post-implantation protocols for ceramic heads.
First of all, wound care is required. Keep the wound dry and clean, avoid water, and prevent infection. And the wound dressing needs to be changed regularly according to the guidance of medical staff.
Secondly, regular follow-up is required. Generally, follow-up is required at one month, three months, six months and one year after surgery. The doctor will determine the specific follow-up frequency based on the recovery status at each follow-up. The follow-up items include X-ray examination, blood routine, hip joint function assessment, etc., so as to timely understand the position of the prosthesis, healing status and overall recovery of the body.
In daily life, avoid excessive bending and twisting of the hip joint. When going up and down the stairs, the healthy side should go first, and try to use the handrail to assist. And within three months after surgery, strenuous exercise and heavy physical labor, such as running and lifting heavy objects, must be avoided.
