With the development of medical treatment, more and more fracture patients are treated with internal fixation, the healing of fractures is getting better and better, and the population of patients with plates in their bodies is getting bigger and bigger. Sometimes, we jokingly say that we can’t catch up with the trend without 2 plates in our body. Joking aside, is it necessary to remove the plates in the body by surgery? Many people are anxious to remove the plates as soon as the bones have grown. In fact, is it necessary to remove the plate? Why do you need to remove it? First of all, it is important to understand that there are many, many human implant materials, such as the most well-known heart coronary stents, implantation is never ready to take, in addition to many, such as, orthopedic internal fixation plate, hernia patch, silicone pad ……? These implanted devices are actually tested before implantation in the human body, in general there is no harm to the human body, in special circumstances, only to have an impact on the human body, such as infection around the implant, the implant contents seepage … The topic is a bit off, back to our orthopedic internal fixation plate, why do you need to open the knife to take it off? Can be discussed from the following aspects: 1, age. Pediatric, adolescents, the presence of internal fixation plate on the body’s development there is a clear, or potential impact, not only need to take out, because of rapid recovery, growth and development needs, but also need to be removed early, as early as possible. Clinicians also generally prioritize the arrangement of internal fixation removal in pediatric patients. 2. Location. The fracture site is close to the joint surface, after the fracture heals, the internal fixation plate exists on the joint activity, this kind of internal fixation material also needs to be removed. Some of the internal fixation screws are driven into for fixing the joint, such as the lower tibiofibular joint fixation screws, lower ulnar radial joint joint joint fixation screws, and the possibility of fracture will occur after a long time. 3.Infection. Infection around the internal fixation is a great disaster, and must be removed at the appropriate time. 4, there are other effects on the body, as well as allergies. A small number of internal fixation material position does not affect the joint, the patient also does not have growth and development problems, but may be due to screw withdrawal, or the patient’s body is thin, the plate obviously rubs against the skin and so on, such also need to consider taking out. Very few patients have allergic reactions to the internal fixation plate, serious skin rupture, plate exposed, such patients need to remove the internal fixation regardless of age. 5.Subjective need. These patients are relatively few in foreign countries, but more in China. Because of the traditional thinking, feel that the internal fixation plate in the body will produce psychological discomfort, so the rate of internal fixation removal in China is much higher than abroad. After discussing why it needs to be taken out, what is the situation that cannot be taken out? 1.Important tissues exist at the site of internal fixation, so it is very risky to remove. For example, in the case of pelvic fracture, there may be adhesions between the internal fixation plate and abdominal organs after surgery, and there is a great risk of injury to the organs when the plate is removed. Or the steel plate is adjacent to the nerves and blood vessels, and the removal may damage the nerves. This kind of steel plate is removed more disadvantages than benefits. 2, older, or poor health, the removal of the surgery has a greater impact on the body, or even affect the life.
