Your cervical spine is made up of the seven bones, called cervical vertebrae, stacked on top of each other in your neck area. The cervical disks are the cushions that lie between the cervical vertebrae and act as shock absorbers to allow your neck to move freely.
Cervical disk replacement surgery involves removing a diseased cervical disk and replacing it with an artificial disk. It is done when the space between your vertebrae has become too narrow and part of your vertebrae or your cervical disk is pressing on your spinal cord or spinal nerves, causing you pain, numbness, or weakness. When these symptoms do not respond to nonsurgical types of treatment, disk surgery may be recommended.
Using an artificial disk to replace your natural cervical disk is a new type of treatment that has recently been approved by the FDA. In traditional cervical disk surgery, the diseased disk is removed and the cervical vertebrae above and below the disk may be fused together. Disk replacement surgery may have the advantage of allowing more movement and creating less stress on your remaining vertebrae than traditional cervical disk surgery.
Loss of space between your cervical vertebrae from cervical disk degeneration, or wear and tear, is common. Cervical disks begin to collapse and bulge with age.
Your symptoms may include:
Just before the procedure starts you will have an intravenous line (IV) started so you can receive fluids and medications to make you relaxed and sleepy. This procedure is usually done under general anesthesia (you are asleep).
A one- to two-inch incision (surgical cut) is made on the side or front of your neck.
The important structures of the neck are carefully moved to the side until the surgeon can see the bones of the vertebrae and the cervical disk.
The cervical disk that is being replaced is removed.
The artificial disk is placed into the empty disk space.
The incision is closed using absorbable sutures (stitches) under the skin. The skin is then carefully closed with sutures that minimize any scarring.
Once you can drink normally, you will be able to start eating your normal diet.
