Why take the surgical plate?

At present, the harm of not taking steel plates and steel nails is actually only one point, that is, stress shielding effect. In the process of fracture, the steel plate and nail can bear the force of the broken end, so the stability of the broken end can be maintained, and the broken end can achieve bone healing under stable conditions. When the fracture heals, the steel plate and the steel nail can also share the strength of the bone and still bear the strength for the bone, so the bone will gradually become osteoporosis due to stress shielding. Seriously, it will even make the cortical bone obviously thinner, and it may lead to a second fracture when it is injured again. Steel plates and steel nails will eventually produce metal fatigue, which will easily lead to the fracture of steel plates and steel nails. Some steel plates are not used, some have a heavier impact, and some have a lighter impact. Because the steel plate bears the load for the fracture and provides stable support for the broken end, the broken end can heal. However, after the fracture is healed, there are also cases where the steel plate bears the strength for the bone, which is called stress shielding. It is relatively better in the parts of upper limbs that are not loaded, but in the parts of lower limbs that are loaded, such as femoral shaft, tibia and fibula, it is particularly easy to form osteoporosis caused by stress shielding, and may even lead to secondary fractures.
