Pediatric fractures have many characteristics not found in adults, and are even very different from adults in some ways, which can lead to adverse consequences if they are not followed for diagnosis and treatment. 1. Epiphyseal plate: Also known as the growth plate, the pediatric-specific growth plate is composed of cartilage cells with rubber-like toughness, which has a shock-absorbing effect and protects the joint surface from severe comminuted fractures common in adults. 2, thick periosteum: pediatric periosteum is not only thick but also has great strength, often forming a strand on one side of the periosteum after a fracture is intact and unbroken. If the three-point orthopedic principle is applied reasonably, the periosteal chain will force the fracture to achieve satisfactory repositioning. 3, pediatric bones have great plasticity: pediatric bones have less inorganic salts than adults, and have more bone holes and Harvard tubes, so they have great plasticity before fracture occurs, soft and easy to bend, and can relieve the concentration of pressure to reduce the occurrence of fractures, and when fractures occur they are often willow fractures and cockle fractures. 4, strong orthopedic ability in growth and development: pediatric bones have a strong ability to correct deformities caused by fractures during growth, and sometimes even very serious angular deformities and certain shortening deformities can be corrected in a few months to a few years. This ability is more obvious in the backbone fracture, and the younger the age, the stronger the corrective ability. 5. Fast fracture healing, the healing process of pediatric fractures is quite fast: because the pediatric periosteum has a strong osteogenic capacity, bone scabs are generated more and faster, and pediatric fractures do not heal very rarely.
