At this stage, there is really only one hazard of not taking plates and nails, which is the stress masking effect. At the time of fracture, the plate and nail can take the stress for the fracture end, so they can maintain the stability of the fracture end and allow the fracture end to achieve bony healing in a stable condition. When the fracture is healed, the plate and nail can also share the force of the bone and still take over the force of the bone, so it will gradually cause osteoporosis due to stress shading of the bone. In severe cases, the bone cortex can even be significantly thinned, which may lead to secondary fractures when re-injured. Steel plates and nails will eventually produce metal fatigue and also lead to fracture of the plates and nails easily.
