Disc Replacement Surgery

Disc arthroplasty is a newer surgical treatment option to cure degenerative disc diseases. It is also called cervical disc replacement. It is the process of removing damaged cervical disc and replacing it with an artificial one.

The main goals of this surgery are to reduce pain and preserve motion.

The deformed disc causes vertebrae and discs to put pressure on to spinal cord and nerves and cause pain especially on your low back. The pressure on the nerves and this chronic pain can be relieved by re-establishing the actual shape of spine. Normal disc functions can be re-established.

Disc arthroplasty is usually conducted under a general anesthesia. Your surgeon will put a horizontal incision on one side of neck. Then he will expose the spine and remove the deformed discs. Decompression of nerves would also be performed. After these, artificial disc will be implanted into the intervertebral disc space. Fluoroscopy is sometime helpful for your doctor to track proper position of damaged disc.
