Fractures can be minor or major, depending on the extent of the fracture and the impact of the fracture on the surrounding tissues. In the end, it depends on the degree of disability and loss of function of the limb caused by the fracture. For example, if the fracture is mild, such as rib fracture or localized green branch fracture, fracture of fracture of fracture, or fracture of insertion, although these fractures are also fractures, they are not even considered as minor injuries because there is no significant impact on the function of the limb after the fracture heals. However, some fracture sites, such as femoral stem fracture and tibiofibular fracture, are very serious, causing damage to the surrounding blood vessels and nerves and even tissue destruction, and usually require amputation treatment, which may be a serious injury for cyanotic fracture.
