The spine is mainly composed of 24 vertebrae and caudal vertebrae, with ligaments and muscles attached around the spine. The physiological curvature of the spine includes the cervical, thoracic and lumbar curvatures with S-shaped sides, which allows the spine to have a cushioning force to carry weight. The human body is impacted by external forces, due to spinal conductivity, it is easy to cause fractures at the spinal flexure, such as cervical 1-2, cervical 5-6, thoracic 11-12 and lumbar spine, most commonly the thoracolumbar segment, such as thoracic 11-12 position. Spinal fractures are easily combined with spinal cord injury, resulting in lower limb weakness and urinary and fecal dysfunction, at which time the spine needs to be kept under braking to avoid aggravating spinal cord injury.
