Neck surgery is necessary when other methods of neck pain treatment such as medications, physical therapy and rest fail, according to Everyday Health. Neck surgery relieves neck pain caused by a nerve root, removes pressure on the spinal cord and prevents vertebrae from grinding against each other.
Bone spurs or herniated disk materials may pinch the nerve root in the neck, causing pain that necessitates surgery, explains Everyday Health. Around 90 percent of patients who undergo surgery to remove herniated disks experience complete pain relief.
Spinal stenosis exerts pressure on the spinal cord, claims Everyday Health. To treat spinal stenosis, a patient should undergo complex neck surgery. In addition, neck surgery is suitable in the treatment of degenerative disk disease to stop the vertebrae from grinding.
