This depends on the firmness of our surgical fixation. If the surgeon chooses a very strong internal fixation during the surgery, it is possible to break and press it, but if the fixation is not strong, it is not possible to break or press it. Why? The purpose of surgery is to provide a strong and stable environment for the fracture end, but if it is not strong enough to provide stability, breaking and pressing will cause the fracture end to be re-displaced, and in serious cases, the plate may break again and the screw may loosen, leading to the failure of the surgery. Any exercise is the same, there must be a degree, too much is too little. Even a strong object has its fatigue level. To use the simplest analogy, when we were small, there was no vise at home, and the way to break the wire was to repeatedly bend the wire, and the wire got hot during the repeated bending process, and then it would break, which is the fatigue of the metal. In fact, plate fixation for fractures is only to provide an auxiliary fixation. As the fracture heals, the plate will play a smaller and smaller role, and when it is completely healed, the plate will have no role. However, if the fracture does not heal and the patient is still active every day, the plate may break or break in other relatively fatigued places, such as the location of the screws. It is common to see stainless steel plates break off in clinical practice. We classify patients into four levels of weight bearing: the first is no weight bearing at all; the second is weight bearing within the range of tolerable pain, which is about 5 kg, that is to say, you can point your toes to the ground like a dragonfly; the third is partial weight bearing, about 30 kg-60 kg; and the other is complete weight bearing. Therefore, when a patient can go down to the ground, there are actually three kinds of situations: the first is full weight-bearing, the second is partial weight-bearing, and the other is weight-bearing within the tolerable pain range, so you can imagine that the weight-bearing is completely different for these three levels. How to determine the size of the weight? Keep a scale at home, put your foot on the scale, the number of kilograms shown on the scale is the weight we are carrying.
