Background
Bones are the hard organs that make up the internal bones of vertebrates, and function to exercise, support and protect the body; manufacturing red blood cells and white blood cells; storing minerals. Bones are composed of a variety of different shapes, with complex internal and external structures, which allow the bones to remain rigid while reducing weight. One of the components of bone is mineralized bone tissue, the interior of which is a rigid honeycomb-like three-dimensional structure; other tissues also include bone marrow, periosteum, nerves, blood vessels, and cartilage. The bones of the human body play a role in supporting the body and are part of the human body's movement system. When a bone (bone) is damaged, a fracture or a bone fracture occurs, and after the fracture or the bone fracture occurs, a splint and a bone nail are required to be used for conveniently recovering the bone nail. In medical clinic, bone fracture is one of the common diseases of bone trauma. A common method for treating fractures is to perform an internal fixation operation, i.e. after reduction of the fracture site, the reduced bones are connected by means of bone plates and screws made of metal materials.
