Common causes of fractures in children include falls, bruises, falls, traffic accidents, fall from height injuries and other factors of unknown origin, with falls and traffic accidents accounting for the vast majority of fracture causes. Children’s own skeletal systems are not fully mature and have more organic matter in their bones. As a result, the types of fractures that occur in children under the same stresses are very different from those in adults. Fractures in children are mostly in the upper extremities and are likely to occur in the clavicle, wrist, elbow, etc. Because of the greater toughness and elasticity of children’s bones, they tend to fracture continuously when encountering external forces and are very prone to bone fractures or green branch fractures. In addition, children have thicker periosteum than adults, so it is not easy to displace the fracture, so most children use non-surgical treatment. A more serious fracture in children is a fracture that causes damage to the epiphysis, which is the center of ossification and can affect the development of the child’s bones if it is damaged. Therefore, it is important to clarify the damage as early as possible after a fracture occurs in children so that the correct treatment can be chosen in time. In the later stages of the fracture, functional exercises should be increased in time to promote the recovery of the fracture.
