Keep Moving: A Patient’s Guide to Motion-Sparing Spine Surgery

When spine problems like a herniated disc or severe stenosis cause excruciating pain, numbness, tingling, or weakness that doesn’t respond to conservative treatments, surgery might be the next step. Historically, the gold standard for many of these issues has been a spinal fusion—a highly successful procedure that connects two bones together to stop painful movement.

However, many patients worry about losing their natural flexibility. This is where motion-sparing surgery, specifically artificial disc replacement, comes in.

What is a Disc Replacement?

Instead of using a metallic cage, plates, and screws to eliminate movement between your vertebrae, a disc replacement involves placing a highly advanced ball-and-socket joint into the empty disc space.

This artificial implant is designed to mimic your spine's natural mechanics, allowing you to maintain your mobility while successfully relieving the pressure on your delicate nerves. A normal disc naturally moves about 4 degrees, and our goal is to preserve that. In fact, many patients report feeling like they have more overall motion after surgery simply because they are no longer restricted by severe pain.

Cervical Disc Replacement (The Neck)

A cervical disc replacement treats nerve compression in your neck, which typically presents as radiculopathy (a pinched nerve causing arm pain, numbness, or weakness) or myelopathy (compression of the large spinal cord itself, which can cause balance and coordination issues).

• The Approach: We use a minimally invasive technique from the front of the neck, making a small 2-to-3-inch horizontal incision that is often hidden in a natural skin fold for a better cosmetic result. Going through the front allows us to gently move aside your windpipe, esophagus, and blood vessels without having to cut any major muscles.
• The Fix: Using a specialized surgical microscope for precision, I carefully remove the damaged disc and any bone spurs that are crushing your nerves. Then, we insert the sleek artificial disc to preserve your natural neck motion.
• The Recovery: Most of my patients go home the exact same day, or after a brief one-night stay for observation.

Lumbar Disc Replacement (The Lower Back)

Similarly, a lumbar disc replacement treats nerve compression and pain originating in your lower back.

• The Approach: We also perform this surgery from the front (anteriorly) through an incision on your abdomen. This approach allows us to carefully move abdominal organs and large blood vessels out of the way, giving us direct access to the front of your spine without cutting through your thick back muscles.
• The Fix: We remove the damaged, degenerative disc—which is often the consistency of crab meat—and replace it with the artificial lumbar ball-and-socket joint.
• The Recovery: Just like with the cervical procedure, this is often an outpatient surgery where patients go home the same day or the following morning.

Am I a Good Candidate?

While disc replacement is an incredible, state-of-the-art option, it is not the right fit for every spine. You may not be a good candidate for a disc replacement if you have:

• A great deal of pre-existing spinal arthritis or large bone spurs.
• Severe disc space collapse.
• Spinal instability or a "slipped" vertebra (a condition called spondylolisthesis).
• Disease that requires surgery across three or more spinal levels.

In these cases, a traditional spinal fusion is usually the safest and most effective way to treat your pain, stabilize your spine, and prevent further nerve damage.

The Bottom Line

Whether you need a cervical or lumbar procedure, my goal is always the same: to take the pressure off your nerves, stop future nerve damage, and get you back to living your life.
