After the fracture has healed, do the plate screws that fixed the fracture have to be removed?" , many patients and their families will ask this question after undergoing orthopedic internal fixation surgery. Many patients and their families even regard the answer to this question as a reference standard for choosing internal fixation devices: if they need to be removed in the future, they should use cheap domestic steel plates; If there is no need to dismantle later, use imported steel plate. In fact, this understanding is wrong. With the progress of raw material industry and the development and update of orthopedic internal fixation devices, the biocompatibility and stiffness of orthopedic internal fixation plate screws used by the vast majority of medical institutions are quite good. The so-called domestic and imported steel plate screw material difference, is a statistical theoretical difference, for example, with imported steel plate screw and domestic steel plate screw under the same conditions of the load fatigue test, 1000 imported steel plate only 1 piece of fracture, and 1000 domestic steel plate there are 6 pieces of fracture, but in fact, The fracture rate of domestic plate in clinical application is very low. Because there are many factors leading to plate fracture, even if the imported steel plate, if the fracture is not healed, then the plate will eventually loose or fracture. As for the steel plate material, some of the quality of domestic steel plate does have some defects, more common is the screw tail and screw rod connection has a weak point of stress, sometimes try to tighten the screw, fracture occurs at the screw tail and screw connection. Or screw tail slip, slip, can not be screwed with a screwdriver. If this happens when the steel plate is removed, it will bring great trouble. Therefore, it is wrong to think that "if the steel plate is removed in the future, domestic steel plate will be used". In fact, for adults, whether the choice of domestic or imported steel plate, the vast majority of steel plate screws are not necessary to remove. The removal of plate screws after fracture healing can only be considered unless there is rejection reaction of the body to plate screws, long-term non-union of the incision, exudation, or loosening of the screw plate, or the plate screws are raised under the skin, stimulating the skin or affecting the sliding of the tendon.
