Burst fracture is a high-energy violent fracture, which causes compression fracture of the thoracolumbar vertebrae, and part of the fracture block is displaced posteriorly, resulting in spinal canal occupation, stenosis, and spinal nerve compression injury. The role of decompression, thoracolumbar burst fracture mostly occurs in car accidents, high fall injuries, mostly in young people, if not surgically repositioned, the vertebral body may be posteriorly deformed and compress the nerve, therefore, for thoracolumbar burst fracture, it is necessary to use the internal fixation and repositioning surgery with the pedicle nail.
