In artificial total hip replacement, bone cement technology is of great significance to the long-term stability of the prosthesis.
The first generation, that is, manual mixing, no emphasis on medullary cavity flushing, no distal plugs, and bone cement filling by hand. The second generation still mixes bone cement by hand, but has recognized the importance of flushing the medullary cavity, uses a distal plug, and injects bone cement with a bone cement gun. The application of the third generation of vacuum stirring, pressurized pulse flushing of the femoral medullary cavity, pressurized bone cement gun for injecting bone cement, femoral prosthesis central device and various types of distal plugs.
Notes and important information about bone cement:
Forehead filling, crown filling, and back of head filling, these three are all filled with bone cement. What is worth mentioning is if If there are muscles on both sides of the filling area, it cannot be filled. As far as the filling effect is concerned, bone cement can achieve a full and corrective effect, which is more in line with the adaptability of our human body. This kind of shaping is relatively long-lasting, and with good living habits, it can even last a lifetime.
The technical aspect is a relatively hard-core thing, but for ourselves, we must understand it. Its safety is also the most noteworthy point for us. The bone cement is certified by the US SPA and the Food and Drug Safety Administration. In terms of material selection, the qualification rate of the materials is strictly checked to ensure that they are harmless to the human body before allowing the hospital to use.
