Spinal fracture dislocation does not necessarily complicate spinal cord injury, depending on the type of fracture, the location of the injury, and not every patient will have a spinal cord injury. Such as high violence injuries of the injured will generally be combined with some spinal cord injury, but the degree of injury depends on the degree of injury, the injury. For example, pathological changes such as osteoporosis or some tumors in the elderly is a chronic compression process, the compression of the spinal cord is relatively less, generally this situation will not occur in acute spinal cord injury. In conclusion, spinal cord injury depends on the fracture, the compression of the fracture fragments on the spinal canal or the dislocation of the fracture.
