Spinal fractures are usually found in the third through sixth cervical vertebrae, the seventh thoracic vertebrae to the third lumbar vertebrae, etc. Spinal fractures are generally violent injuries, and the greater the mobility of the area, the greater the chance of fracture. Also the spine has a physiological curvature, and the greater the physiological curvature, the more likely it is that a fracture will occur due to the mechanics of gravity transfer. Spinal fractures are high-energy injuries that occur in areas of greater physiological curvature. For example, the lower cervical spine is anteriorly convex, the thoracic spine is posteriorly convex, the thoracic tenth to the thoracic twelfth is the most important part of the posterior convexity, and the lumbar one is anteriorly convex, so the good parts of the spine fracture are the parts with greater physiological curvature.
