Posterior cervical spine surgery is performed to address cervical spinal stenosis. The main risks and side effects of the surgery are: the cervical spine is the center of the high position of the human body, and there is a risk of injury to the spinal cord. If the spinal cord of the cervical spine is damaged, there will be numbness of the limbs, abnormal sensation, or even paralysis, and there is also a risk of impairment of the second stool. The opening of the spinal canal is prone to bleeding, and the canal may not heal later, leading to neck pain and discomfort. Neck surgery is prone to infection and non-healing of the incision, which can mostly be healed and relieved by changing the medication. In general, if surgery is needed for cervical stenosis, it is recommended that it be done as soon as possible, otherwise it is not conducive to recovery.
