Children are very active by nature and are prone to 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 epiphyseal plate 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 length of bones grow. After puberty, the epiphyseal plate gradually loses its ability to proliferate, and the bones stop growing. If the epiphyseal plate is damaged due to trauma, the growth and development of bones will be affected. Compared with adults, pediatric bones contain 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 a young branch breaking, showing the 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. Pediatric fracture healing is different from that of adults and has the following characteristics: 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. Pediatric fractures rarely fail to heal. High orthopedic capacity: Pediatric bones have a more advanced ability to correct deformities caused by fractures during growth and development, and even if the fracture has some misalignment (sometimes even more pronounced misalignment), it can be corrected months to years later without leaving any sequelae, as long as the fracture force line is satisfactory and the rotation and shortening displacement are corrected. The principles and methods of management of pediatric fractures are very different from those of adults due to the above-mentioned skeletal structure and fracture healing characteristics. If the physician or the child’s family does not understand these characteristics, the pursuit of anatomical alignment of the fracture will cause unnecessary trauma and greater pain to the child. For the treatment of pediatric fractures, Western medicine is more likely to use incision and internal fixation, which has the advantage of stronger fixation and the disadvantage of greater surgical trauma. The TCM treatment for pediatric fracture is more often the method of external fixation by closed repositioning splint (or plaster), the TCM orthopedics has a whole set of fracture repositioning methods, and closed repositioning of fracture is the most distinctive feature of TCM orthopedics.
