The role of orthopedic plates is to maintain the stability of the fracture end. When a fracture is created, some of the fractures can be treated conservatively, such as cast fixation and splint fixation, and there is no need for surgery or plate fixation at this time. In fact, many fractures are unstable fractures, so plaster and splinting are not useful for treatment, and orthopedic plates are needed at this time. The orthopedic plate implanted into the body can ensure that the fracture end is not under stress, and the fracture end can only gradually heal under relatively stable conditions, and the orthopedic plate plays the role of stability. The fracture can be healed smoothly by fixation with plates and nails, while there is no way for the fracture to grow without plates.
