Bone fracture

An open bone fracture is the rupture of the skin or mucous membrane at the fracture site, and the fracture communicates with the outside world. The biggest danger of open fractures is that the wound is contaminated, a large number of bacteria invade, and they rapidly multiply locally, resulting in bone infection. Open fractures can be divided into three degrees according to the degree of soft tissue damage: ① the skin is punctured from the fracture end from the inside to the outside, and the soft tissue damage is light; ② the skin is broken or crushed, and there is moderate damage to the subcutaneous tissue and muscles; Subcutaneous tissue and muscle are severely damaged, often accompanied by vascular and nerve damage.
