Surgery Overview

Spinal decompression surgery reduces pressure on the spinal cord, Opens dialog or spinal nerve roots, Opens dialog.

Surgery is only done to relieve severe symptoms caused by pressure on the nerve roots. This pressure may cause neck pain, but it can also cause arm pain, numbness, or tingling; leg pain, numbness, or tingling; or problems with bladder or bowel control. In these cases, surgery may not help the neck pain itself, but it usually helps relieve other symptoms.

To relieve the pressure, your doctor may remove:

• Bony growths (bone spurs or osteophytes) and fibrous tissue that are narrowing the spinal canal, Opens dialog and pressing on spinal nerve roots.
• Parts of the vertebrae (laminectomy) to enlarge the spinal canal, to relieve pressure on the spinal nerve roots.
• Disc material (discectomy) from a herniated disc, Opens dialog that pushes into the spinal canal.

In some cases, after bone and disc material are removed, the affected bone (vertebrae, Opens dialog) parts may be joined together (spinal fusion, Opens dialog) to stabilize them.
