Disc Replacement Q & A

What is disc replacement surgery?

Disc replacement surgery involves removing damaged or worn discs from between your vertebrae and replacing them with artificial discs.

Spinal discs are protective pads that have a tough outer layer and a jelly-like inside. They sit between each vertebra, cushioning the bones and preventing injury. If the discs are damaged or start to deteriorate, they can put pressure on nearby nerves or the spinal cord, causing pain and altered sensation, and affecting movement.

The benefit of disc replacement surgery over spinal fusion, which is an alternative treatment approach for the same kinds of conditions, is that the artificial discs give you a better range of movement than is possible with fusion.

Why would I need a disc replacement?

If you have a back or neck condition, in most cases, you start your treatment with conservative approaches such as physical therapy and steroid injections. These are effective for most patients, but for some, conservative treatments don’t relieve their pain or improve mobility.

If this is the case, then surgery might help. Disc replacement surgery is effective in treating several conditions that develop because of damage or deterioration of the discs, including:

Degenerative disc disease

With advancing age, the spinal discs start to dry out, becoming more flat, harder, and less effective.

Herniated discs

Herniated discs are ones where the jelly-like inside pushes through a weak spot in the outer layer of the disc.


Spondylolisthesis is a condition where one vertebra slides over the top of its neighbor because the discs are deteriorating.

Spinal stenosis

Spinal stenosis can develop from severe degenerative disc disease, herniated discs, or spondylolisthesis, which cause a narrowing of the spinal canal and put pressure on the nerves.

Am I a candidate for disc replacement?

Before recommending disc replacement surgery, Dr. Nkrumah needs to be sure you’re a suitable candidate, and determine if surgery is the best option. To achieve this, he carries out a thorough physical exam, runs diagnostic imaging tests, and reviews your previous treatments.

To undergo disc replacement surgery, you need to have a general anesthetic. Lumbar disc replacement surgery typically takes 2-3 hours and is carried out through an incision in your abdomen, so Dr. Nkrumah can reach your spine without interfering with the nerves.
