Clinically, fractures are broadly classified into two categories: traumatic fractures and pathological fractures according to the cause of fracture. Pathological fractures are mainly spontaneous fractures of bones caused by various orthopedic diseases, such as osteomyelitis, bone tumors, osteoporosis, etc. Such spontaneous fractures of bones caused by orthopedic diseases following bone destruction are usually pathological fractures. Traumatic fractures are divided into direct violence fractures, indirect violence fractures, and fatigue fractures, depending on the type of force of injury. A direct violence fracture is better understood as a fracture caused by the direct application of force to the fracture site. Indirect violence fracture is a fracture caused by the transmission of force to a more distant part of the injured area after the injury, mainly through the action of leverage. Fatigue fractures are fractures caused by the accumulation of chronic forces on a part of the bone over a long period of time. Depending on whether the fracture is connected to the outside world, it can be divided into open fractures and closed fractures. Depending on the completeness of the fracture, it can be further divided into complete and incomplete fractures. According to the type of fracture line, it can be divided into transverse fracture, oblique fracture, comminuted fracture, inset fracture, bruxism fracture, etc.
