The purpose of first aid for fractures is to provide simple and effective treatment after a fracture has occurred to achieve injury reduction, prevent infection and prevent re-injury, which can ultimately contribute to effective follow-up treatment. After a fracture has occurred, the patient should first be stopped from moving to avoid re-injury and should be kept in a relatively relaxed position. The traumatized area should be stopped from bleeding or simply bandaged. If conditions allow, ice bags can be placed on the injured area, with towels or clothing between the ice bag and the skin, and direct contact of the ice bag with the skin is prohibited to prevent frostbite, and the duration of the ice pack should not exceed 20 minutes. For displaced fractures, pulling on the fracture site should be avoided as much as possible. Simple fixation and wrapping of the fracture site should be done locally as far as possible. Be careful not to fixate and wrap too tightly to avoid new injuries. Multiple people should work together when moving the patient. If injuries to the head, neck, spine, etc. are suspected, at least three people should be transported together, one to fix the head and two to support it with flat hands, and all three should work together to prevent re-injury. After simple treatment of fractures, it is important to seek medical attention in a timely manner to prevent delays.
