Whether a broken cervical spine will cause paralysis depends on how severely the cervical spine injury is compressing the cervical medulla. If the cervical spine injury compresses the cervical medulla very severely, it will cause paralysis of the limbs. If the injury to the cervical spine is not very severe, and only a localized area of the cervical marrow is compressed, the symptoms will be correspondingly mild, and the corresponding symptoms of the compressed area, such as dysfunction of a limb, will occur. Generally, cervical spine injury is a more serious injury that requires timely treatment because the damage that occurs after the cervical medulla is compressed is irreversible, so once the cervical medulla is compressed, timely surgery should be performed to decompress it. If the long-term compression, because the injury is irreversible, will cause permanent loss of function, early release of compression is conducive to the restoration of spinal cord function, the restoration of limb function, to reduce the sequelae caused by the disease.
