Children are very active by nature and are prone to various fractures because of their poor awareness and ability to protect themselves. The bone tissue structure and fracture healing characteristics of pediatric patients are very different from those of adults, and they also have their own characteristics in the treatment of fractures. The growth plate, located at the ends of the bones of children, is a special structure that maintains the growth of bones. The cells in the cartilage of the epiphyseal plate are constantly differentiating and proliferating, making the bones grow in length. After puberty, the epiphyseal plate gradually loses its ability to proliferate and the bones stop growing. If the epiphyseal plate is damaged by trauma in children, the growth and development of bones will be affected. Compared with adults, pediatric bones have more organic matter and less inorganic matter, so the toughness of the bone is high and the brittleness is low, and the fracture caused by the injury is often like the breaking of a young branch, showing a bending of the bone or only a partial fracture, which is clinically called “green branch fracture”. Of course, if the external force is very high, the bone will be completely broken and obviously misaligned. The fracture heals quickly: after the fracture, the periosteum cells on the bone surface differentiate and proliferate to produce new bone, which connects the two ends of the fracture until it heals. Pediatric periosteum has a strong osteogenic capacity, and new bone is produced quickly and abundantly, resulting in a significantly shorter healing time than adults, such as a supracondylar humerus fracture, which takes only 2 weeks for a pediatric patient to achieve initial healing. Pediatric fractures rarely fail to heal. Strong orthopedic ability: Pediatric bones have a strong ability to correct deformities caused by fractures during growth and development. As long as the fracture force line is satisfactory and rotation and shortening displacement are corrected, even if the fracture has some misalignment (sometimes even more obvious misalignment), it can be corrected in a few months to years without any sequelae.
