Cervical vertebrae broken has many hazards, including the following serious points: First, after the neck is broken, the cervical spinal cord is compressed, because the cervical spinal cord exists in the human body’s “center of life”, it may be compressed ischemia, hypoxia and other manifestations of the human body’s respiratory failure and lead to human death. Secondly, the cervical spinal cord is composed of many important nerve roots, which can lead to irreversible nerve damage and paraplegia. Thirdly, the cervical region is rich in blood vessels, if the cervical vertebrae are broken, a hematoma will form and compress the spinal cord, resulting in respiratory failure or paraplegia and other major manifestations.
