We are no strangers to fracture, which is a relatively common disease in daily life, usually caused by external injuries. After trauma, local soft tissue swelling is obvious, and accompanied by localized pain, it is usually related to the white bone, at this time do not easily move the local, so as not to lead to fracture dislocation caused by the fracture of blood vessels and nerve damage. There are many types of fractures, and the treatment of different types of fractures is different. Today we will focus on understanding how many types of fractures. First, according to the shape of the fracture can be divided into nine types 1, transverse, oblique and spiral fracture, this kind of fracture occurs in the bone cadre. 2, comminuted fracture, bone broken into more than two pieces, can be called comminuted fracture. When the fracture line is “T”-shaped or “Y”-shaped, it is also called “T”-shaped fracture or “Y”-shaped fracture. Compression fracture, cancellous bone is often deformed due to compression, like vertebrae and heel bone. 4, stellate fracture, this is mostly due to violence directly on the bone surface, such as skull and patella can occur stellate fracture. 5, depression fracture, is the skull due to external force to make part of the depression. Embedded fracture occurs at the junction of cortical bone and cancellous bone in the metaphysis of long tube bone. After the fracture, the cortical bone is embedded into the cancellous bone, which can occur in the neck of the femur and the surgical neck of the humerus and other places. 7, crack fracture, such as the long bone or skull after injury may have fracture line, but not through all the bone. 8, green branch fracture, mostly occurring in children, part of the bone broken, periosteum and part of the bone is not broken. 9, epiphyseal separation, through the epiphyseal fracture, epiphyseal section can be with varying amounts of bone tissue, is a kind of fracture. Second, according to whether the fracture and the outside world can be divided into two kinds of fracture 1, a kind of skin is not broken, there is no wound, the broken bone is not connected with the outside world, called closed fracture. The skin or mucous membrane at the closed fracture is intact and does not communicate with the outside world. There is no contamination in this type of fracture. 2. The other type of fracture is one in which the tip of the bone passes through the skin and there is a wound that communicates with the outside world, called an open fracture. Open fracture fracture near the skin and mucous membrane rupture, because of the connection with the outside world, such fracture wounds and fracture breaks are contaminated. Third, according to the degree of fracture, can be divided into two 1, complete fracture, the integrity or continuity of the bone all interrupted, tubular bone fracture after the formation of distal and proximal two or more fracture segments. Transverse fracture, oblique fracture, spiral fracture, comminuted fracture, kanji fracture, compression fracture, depressed fracture and epiphyseal separation are all complete fractures. Incomplete fracture, the integrity or continuity of the bone is only partially interrupted, such as skull, scapula and long bone cleavage fracture, children’s green branch fracture and so on are incomplete fracture.
