Brief Introduction of Hip Replacement 5
Jun. 02, 2020
Since 2003, many companies have completed IDE procedures, and their ceramic-to-ceramic hip joints have been approved by the US FDA, but the technology still belongs to the third type of implant. Over the past decade, the application of ceramics to ceramic hip replacements has been quite frequent. Reading the literature, we can find that the characteristics of alumina ceramics with low wear and no osteolysis have not changed. With further refinement in the engineering technology of metal and ceramic prostheses, the trend toward the design of fourth-generation alumina-based composite materials has begun to increase the use of large-diameter femoral heads, which is Diameter femoral heads compete. The advantages of ceramic large-diameter femoral heads are obvious. It can increase the stability of the prosthesis while reducing the risk of fracture of the prosthesis because the larger ball head is less likely to fracture.
In the past ten years, the abnormal noise during the use of ceramic load-bearing surface has been widely criticized. In the initial stage of use, almost no such problems have occurred. Then there were quite a few case reports. Subsequent research did not find the real source of abnormal noise, but it is generally believed that the production of this sound is a "system" problem, and the incidence is quite high in a specific prosthetic system. Although the incidence of abnormal noise in systems using fourth-generation materials may decrease, it is still a risk factor.
When writing this brief history, readers will agree from reading the following literature that ceramic materials and prosthesis designs are steadily improving. Since the particles produced by ceramics hardly cause wear and tissue reactions, their clinical results are excellent. With the advent of a cup of multi-lined acetabular cups, and the fourth generation of ceramic materials eventually used on the femoral and acetabular sides, ceramic-to-ceramic total hip replacement is still a very attractive option for young active patients.
