I believe many people are not unfamiliar with orthopedic internal fixation materials. After orthopedic patients undergo surgery, many of them will ask some questions about the plate. Here are 7 questions and answers to clear your doubts. 1, the plate must be removed? Now the internal fixation is mostly titanium alloy material, rejection is very small, in theory, can not take. Foreigners are generally not to take, one because the medical insurance does not reimburse, and foreigners think it is not a matter. Chinese people are not, always feel that the body more than one foreign body is a heart disease, so many people eventually took out the internal fixation. In fact, think about the many revolutionary predecessors in the body have a lot of shrapnel, not to take a lifetime, but also fine. Our plate is much more advanced than shrapnel. 2.What is the right time to take out after surgery? Generally, the weight-bearing parts of the lower extremity are more suitable to be taken out 1.5-2 years after the fracture line disappears, and the upper extremity is generally more suitable to be taken out 1 year after the fracture line disappears, if you want to take out the internal fixation, it is fine later than the above time. But not early, take early is easy to fracture again; also not too late, more than 3-5 years is difficult to take out. In addition, the domestic device company can not last long, it is likely that 5 years later the company that provided the plate has disappeared. 3, why which hospital to do the surgery, to go back to that hospital to take out the plate? Because some screwing tools are not uniform, if the internal fixation is performed in the outside hospital, to this hospital to take, it is possible that the tools do not match and cause the removal failure. Just like the phone charger is not suitable for charging, in case you can’t get it out is not let you suffer for nothing, for safety reasons, for your sake, or back to the original hospital to take it out. 4.Which is better: imported steel plates or domestic ones? To be honest, imported steel plates are better than domestic materials in terms of material and workmanship. But at the same time, the imported steel plate is more expensive than the domestic steel plate, generally one-third or even one-half of the price of the domestic steel plate. Can’t domestic steel plate be used? Of course not, domestic steel is also in line with national standards. Just like domestic cars and imported cars. Why do many people prefer imported cars? Although both cars can reach the destination, but the quality, safety factor, workmanship and other aspects of imported cars are still superior to some. Of course, there is no need to tighten the belt must use imported materials, because the domestic steel plate has progressed rapidly in recent years, the quality can also be guaranteed. 5, deep steel plate is generally not taken. For example, the pelvic steel plate is too deep, and the removal operation is very damaging, so doctors generally recommend not to take it. 6.Is there any absorbable material? Yes, but it is not made of steel. It will gradually absorb with time and eventually disappear. However, this material is not strong enough and is usually used in non-weight-bearing parts. At the same time, because the degradation speed is not adjustable, once the fracture healing is slower than the degradation speed, it is easy to fail the surgery, so the current amount is small. 7.Can the plate be used twice? Of course not. Metal fatigue will be produced during the fixation of the internal fixation, and this fatigue is not recoverable, which means that the internal fixation has its life. The used internal fixation is the one that has completed its mission, and its material mechanical properties cannot support the treatment of new fracture. In addition, China’s management of medical devices is based on strict laws, internal fixation is a disposable medical supplies, the State Council “Medical Device Supervision and Management Regulations” provides that single-use medical devices may not be reused, if the violation, the administrative penalties for manufacturers, agents and hospitals is absolutely running out of money, not to mention the huge civil compensation and criminal sanctions, who dare?
