When the bone is subjected to too much external force, it can be called a fracture, whether it is cracked, broken or deformed. In addition, there are other causes of fractures that are not caused by severe external forces, but are gradually formed by accumulated stress, such as fatigue fractures, or when the composition of the bone is changed (most commonly osteoporosis) and can not bear the force, can also cause fractures.
Generally, according to whether the broken bone penetrates the skin and contacts the outside world, it can be divided into two categories: one is simple fracture, or closed fracture, the broken bone does not protrude from the skin surface, so there is no risk of infection. The second is a complex fracture, or an open fracture. The broken bone protrudes from the skin surface to contact the outside world, resulting in an open wound. In severe cases, bacteria may invade the bone marrow cavity and cause more serious infection. The treatment of complex fractures is cumbersome and difficult, so it can be further subdivided into different types, and doctors formulate different treatment strategies according to the situation.
Fractures are also related to the development of bones. In childhood, bones are still developing, with more cartilage components and better elasticity; most of the cartilage in adult bones has been converted into hard bones; bones in old age may appear osteoporosis. , bones are like beams and pillars that have been eaten by termites, becoming fragile and brittle, and prone to more serious sequelae. According to the state of skeletal development in different periods, physicians' treatment strategies also need to be adjusted accordingly.
