In the later stages of rehab, do all fractures that are not angled need to be broken hard? For example, if a forearm fracture heals and is not angulated after rehab, will pressure break it? This depends on the firmness of our surgical fixation. If the surgeon chooses a very strong internal fixation during surgery, you can break and press it, but if the fixation is not strong, you can’t 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. As with any exercise, there must be a degree, too much is too little. The material of internal fixation, such as steel plate, is so hard that it will break. Even the strongest object has its fatigue. To make the simplest analogy, when we were small, there is no vise at home, want to break the steel wire is repeatedly bending the wire, repeatedly bending process the wire will be hot, then it will break, which is the fatigue of the metal. Since the steel plate of internal fixation will break, do patients still need to use this? Can it be replaced by a better one? In fact, plate fixation is only meant to provide a secondary fixation for fractures. As the fracture heals, the plate will play less and less of a role, and when it is completely healed, the plate will be useless. However, if the fracture does not heal and the patient is still active every day, the plate may break or break in other relatively fatigue areas, such as the location of the screws. It is common to see stainless steel plates break off in clinical practice. When rehabilitating, many people think that if I can get down to the floor, I can bear weight. This is definitely not true. There are 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, you can point your toes like a dragonfly; the third is partial weight-bearing, which is about 30 kg-60 kg; and the third is full 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.
