Background

Orthopedics is one of the most common departments in all hospitals, and mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and maintains and develops the normal form and function of the system by using medicines, operations and physical methods. With the change of times and society, the orthopedic injury spectrum has obvious changes, for example, diseases such as osteoarticular tuberculosis, osteomyelitis, poliomyelitis and the like are obviously reduced, and the injuries caused by traffic accidents are obviously increased. The change of the orthopedic injury spectrum requires the orthopedics to be advanced with time. With the development of material science, some complex fractures can also be treated by internal fixation; the functions and performances of the artificial joint and the artificial vertebral body are more perfect. In summary, the development of bone science is indistinguishable from the development of basic medicine, particularly experimental medicine and material science.

In the steel plate screw internal fixation, the shape of the medical steel plate is matched with the physiological bending of the fracture part, so that the good inosculation between the medical steel plate and the fractured bone is ensured, the fixation effect of the fractured bone and the firmness of the medical steel plate after the medical steel plate is fixed by the screw are improved, most of the existing medical steel plates are processed according to the position and the specification, and the physiological difference of different cases is difficult to be considered.
