Cervical Spine Problems: Disk

The spine has three natural curves. The cervical curve is located in the neck. It forms the top part of the spine. For this reason, it is also called the cervical spine. This sheet tells you more about the parts of the cervical spine and damaged disks. This is a common problem that can affect the cervical spine, but most people don’t need surgery for this. 

A healthy cervical spine

The spine is made up of the following:

  • Vertebrae. These are bones stacked like building blocks that make up the spine. The neck contains the first seven vertebrae of the spine.

  • Disks. These are small pads of tissue that lie between the vertebrae. They help cushion and protect the vertebrae when you move.

  • The spinal cord. This runs through a large central opening (spinal canal) formed by the vertebrae.

  • Nerves. These branch from the spinal cord and carry messages to the body.

  • Foramina. These are smaller openings in the vertebrae. Nerves travel to your arms and other parts of your body from the spinal cord through these openings.

Damaged disks in the cervical spine

One of the most common cervical spine problems is a damaged disk. A disk may be injured by a sudden movement, causing a disk to bulge or break open (herniate). Or a disk may wear out slowly over time (degenerate). A worn-out disk may become so flat that the vertebrae above and below it touch or slip back and forth. As disks wear out, abnormal bone growths (bone spurs) can form on the vertebrae. Bone spurs can also form in the foramina, causing them to narrow (stenosis). If your healthcare provider suspects that you have a damaged disk, tests may be done to confirm the problem, such as an MRI, CT, or EMG. Your healthcare provider will then work with you to plan treatment as needed.
