Am I a Candidate for Cervical Disc Replacement?

You may be a good candidate for cervical disc replacement if you have a damaged or herniated disc causing nerve compression. You may also get a disc replacement if nonsurgical treatment has not relieved your symptoms. However, your surgeon will assess your bone health, spinal stability, and facet joints before recommending surgery.

At Total Orthopedics & Sports Medicine, our spine surgeon, Dr. Dante Leven, helps you make an informed decision about cervical disc replacement. He compares your symptoms with your imaging results to determine whether preserving natural motion may benefit you. Instead of recommending surgery based on one scan, he evaluates how your neck problem affects your movement, function, and daily life. Call 855-321-6784 to schedule your appointment.

Who Qualifies for Cervical Disc Replacement?

You may qualify for cervical disc replacement if a herniated or degenerated disc is pressing on a nerve or the spinal cord. Your symptoms should match the nerve affected by the degenerative disc disease, as shown on imaging. Besides that, you need adequate bone strength, stable vertebrae, and healthy facet joints to support natural movement after cervical disc surgery.

Before recommending surgery, your doctor will also review the symptoms caused by nerve or spinal cord compression, such as:

• Chronic neck pain and stiffness
• Symptoms that spread into the shoulder, arm, or hand
• Numbness or tingling in the arm or fingers
• Weakness in the shoulder, arm, or hand
• Reduced grip strength or hand coordination
• Difficulty with fine hand movements
• Burning, sharp, or electric-like nerve pain
• Loss of sensation in parts of the arm or hand
• Hand clumsiness or dropping objects

However, not everyone with symptomatic cervical disc disease qualifies for disc replacement. A study of 167 patients considered for cervical spine surgery found that only 43% qualified for cervical disc arthroplasty. This low percentage shows that your eligibility also depends on spinal stability, the number of affected levels, and the extent of degeneration.

How Does a Spine Surgeon Evaluate Your Candidacy?

Dr. Dante Leven reviews your MRI and X-rays to determine whether you are a candidate for cervical disc replacement. He evaluates disc height, spinal alignment, surrounding soft tissues, movement at the affected level, and the condition of your facet joints. He also checks for instability, severe arthritis, or bone weakness that may change the recommended surgical approach.

In addition, our spine surgeon examines the diseased disc along with the surrounding areas of your cervical spine. He assesses the location of the damaged disc, movement at that level, and the health of the surrounding spinal structures. He also reviews other changes that may affect your treatment choice, including:

• Severity of nerve or spinal cord compression
• Bone spurs that may restrict normal movement
• Condition of the vertebral surfaces that will support the artificial disc
• Degeneration in the discs above and below the affected level
• Narrowing around the spinal cord or exiting nerves
• Previous surgery at or near the affected spinal level
• Signs of pinched nerves or abnormal pressure on the spinal cord
• Number of cervical levels contributing to your symptoms

If your MRI or X-rays show multiple problems, it may be difficult to know which ones actually affect your eligibility for cervical disc replacement. Dr. Dante Leven can review these findings and explain how each one may affect your treatment plan. Contact us to find out if disc replacement is right for you.

Should Your MRI Findings Match Your Symptoms?

Yes, your MRI findings should generally match your symptoms before your surgeon recommends cervical disc replacement. For example, pressure on a specific nerve may cause pain, numbness, or weakness in the area that nerve controls. This connection helps your surgeon confirm which disc is causing the problem before recommending surgery.

What If You Have Neck Pain but No Numbness?

You may still qualify for cervical disc replacement if you have neck pain without numbness. But your doctor first confirms that a damaged cervical disc is the source of your pain. Because neck pain can arise from several structures, your physical examination and imaging help pinpoint the source of the problem.

During your physical examination, the doctor checks where the pain starts and whether certain neck movements make it worse. They also assess your range of motion, muscle strength, reflexes, and areas of tenderness. Pain triggered by specific movements can help your doctor identify which part of your neck is causing the pain.

How Long Should You Try Nonsurgical Treatment?

You should generally try nonsurgical treatment for at least six weeks before considering cervical disc replacement. In fact, an FDA clinical trial required about six weeks of nonsurgical treatment before cervical disc replacement. During this period, your healthcare provider may use medications, activity changes, or epidural steroid injections to manage your symptoms. If your symptoms continue despite these treatments, your surgeon may recommend surgery to relieve the pressure on the affected nerve.

But you may not need to wait the full six weeks if your symptoms are getting worse. Increasing arm or hand weakness, loss of coordination, difficulty walking, or signs of spinal cord compression may require an earlier surgical evaluation. In these cases, delaying treatment could allow neurological problems to progress.

Can Two Cervical Discs Be Replaced at the Same Time?

Yes, two cervical discs can be replaced during the same surgical procedure when both damaged levels are causing your symptoms. Your surgeon evaluates each level separately to confirm that it can safely support an artificial disc. If both disc levels meet the necessary criteria, total disc replacement can help preserve movement at two levels of your cervical spine.

A prospective randomized FDA trial evaluated 209 patients who received cervical disc replacement at two adjacent levels. The findings showed that both treated levels continued to maintain motion at 10 years. Similarly, a review of two large randomized trials found that two-level cervical disc replacement provided sustained results for 5 to 10 years.

Note: Two-level disc replacement is usually performed on adjacent cervical levels, such as C4–C5 and C5–C6. Your surgeon will also confirm that the artificial disc is approved for use at both affected levels.

What If You Have Arthritis in the Facet Joints?

You may not qualify for cervical disc replacement if you have severe arthritis in the facet joints. Because disc replacement maintains motion, the facet joints must continue supporting movement at the treated level. If they are significantly damaged, continued neck movement may cause pain, making spinal fusion a more suitable option.

To decide whether facet joint arthritis affects your surgical candidacy, your surgeon may assess the following factors:

• Joint narrowing, bone spurs, or cartilage damage on CT or X-rays
• Pain triggered by extending or rotating your neck
• Remaining movement at the affected spinal level
• Abnormal movement on flexion-extension X-rays
• The condition of both facet joints at the affected level
• Main source of your pain: the disc, facet joints, or both

Based on these findings, the surgeon determines how well the facet joints will handle continued movement after surgery. If the joints are already a major source of pain, replacing the disc may not address the entire problem. In that case, spinal fusion may better limit painful movement at the affected level.

Can Osteoporosis Affect Your Surgical Options?

Yes, osteoporosis can affect your surgical options because artificial disc replacement requires strong bone for stable support. If your bone density is too low, the implant may not remain securely positioned between the vertebrae. Therefore, your surgeon will assess your bone quality before recommending replacement surgery.

To assess your bone quality, your surgeon may use a DEXA scan if your age, fracture history, medications, or medical history suggest reduced bone strength. This is because weak bone can allow the artificial disc to sink into the vertebra, known as implant subsidence. Subsidence can reduce disc height, alter alignment, and affect implant function.

How Can Neck Alignment Limit Your Treatment Options?

Poor neck alignment can place extra stress on the artificial disc and the surrounding spinal structures during movement. Your surgeon may use standing or flexion-extension X-rays to see how your vertebrae line up as your neck moves. If the alignment is significantly abnormal, spinal fusion surgery may provide better stability.

An abnormal curve on your X-ray does not always rule out disc replacement. For example, “straightening” or “loss of cervical lordosis” means your neck has lost some of its normal inward curve. Your surgeon then checks whether this curve improves as your neck moves. If it remains flexible, disc replacement may still be an option. In contrast, a fixed curve may require a different surgical approach to achieve better alignment and stability.

Is Disc Replacement Possible With Spinal Instability?

No, you may not qualify for disc replacement if the affected spinal level is unstable. An artificial disc is designed to maintain movement rather than stabilize an unstable spinal level. If the vertebrae move more than they should, disc replacement may not provide enough support.

At the same time, instability at one level does not mean your entire cervical spine is unstable. If several discs are affected, your surgeon assesses each level separately because some may remain stable while others move abnormally. These findings help your surgeon identify which levels need stabilization and which may still safely maintain movement.

Is There an Age Limit for Cervical Disc Replacement?

No, there is no single limit for cervical disc replacement age. Rather than relying on age alone, your surgeon reviews your bone strength, facet joint health, and movement at the affected level. Your age must also meet the FDA guidelines for the artificial disc your surgeon plans to use.

In practice, surgeons often consider younger and middle-aged adults, particularly those under 60, for cervical disc replacement. A clinical review also reports that the procedure may be less suitable after age 60. This is because age-related changes can reduce spinal movement and increase wear on the facet joints. Still, your age alone cannot decide your eligibility for surgery. Your surgeon assesses your overall spinal condition before recommending the most suitable option.

Does a Previous Neck Surgery Affect Your Eligibility?

Yes, prior neck surgery can affect your eligibility for disc replacement, but it does not automatically limit your surgical options. Your surgeon reviews which level was previously treated and how it has healed. Then they assess whether the level being considered for disc replacement still has enough movement and stability.

Here is how a previous cervical spine surgery may affect your eligibility for disc replacement:

• A prior fusion may increase stress on the adjacent discs.
• Scar tissue may make it difficult to safely reach the affected disc.
• Existing hardware or a bone graft may affect the placement of an artificial disc.
• Changes in spinal alignment after prior surgery may affect the surgical approach.
• Previous surgery at the same level may change the available bone and anatomy.
• Instability at the new treatment level may require stabilization rather than motion preservation.
• Limited movement at one spinal level can shift more motion to the levels above and below it.
• An active local or systemic infection can disqualify candidates for the procedure.

You may have been told that age, arthritis, bone loss, spinal instability, or previous neck surgery could affect your eligibility for cervical disc replacement. However, a single factor does not always determine your eligibility. Rather than focusing on one finding, our spine surgeon, Dr. Dante Leven, evaluates how all these factors affect your candidacy for disc replacement. He explains which findings may rule out disc replacement and which may still allow you to preserve movement. Schedule an evaluation with Dr. Dante Leven and get a clear answer about your surgical options.

When Is Disc Replacement Preferred Over Fusion?

Disc replacement may be preferred over fusion when the damaged spinal level can safely maintain movement after surgery. Instead of joining two vertebrae together, the artificial one replaces the damaged disc and maintains movement similar to a healthy disc. This can help preserve motion at the treated level while relieving nerve compression.

Disc replacement may also be preferred when maintaining movement could help lower the risk of adjacent segment disease. For instance, fusion eliminates motion at the treated level, which may increase mechanical demands on the levels above and below it. On the other hand, disc replacement maintains motion at the treated level. A 10-year randomized study also found a lower rate of subsequent adjacent-level surgery after disc replacement than fusion.

Can You Get a Second Opinion Before Surgery?

Yes, you can get a second opinion before cervical spine surgery, especially if you are unsure which procedure is right for you. Another spine surgeon can review your diagnosis, imaging, and recommended procedure. This can help confirm whether disc replacement surgery, fusion, or continued nonsurgical treatment is appropriate for your condition.

Here’s how our spine surgeon, Dr. Dante Leven, reviews your case during a second-opinion consultation:

• Match your MRI findings with your pain, weakness, and other symptoms.
• Confirm which spinal discs are actually causing your symptoms.
• Assess remaining movement before considering motion-preserving solutions.
• Identify arthritis, instability, or alignment problems that may require surgery.
• Review how the proposed surgery may affect nearby spinal levels.
• Compare the expected benefits and limitations of each surgical technique.
• Evaluate your response to conservative treatments before confirming the need for surgery.
• Explain which findings support the original recommendation and which may support another approach.

If another doctor has recommended another cervical spine surgery, you may want to know if preserving neck movement is still possible. In such cases, Dr. Dante Leven can review the findings behind that recommendation. He then checks whether the affected disc still has enough movement and stability for disc replacement. Contact us to schedule a second-opinion evaluation with Dr. Dante Leven before deciding on surgery.

How Successful Is Cervical Disc Replacement?

Cervical disc replacement can have an overall success rate of about 80% at 10 years in carefully selected patients. The procedure can relieve pain in the neck and arm while maintaining movement at the treated level. Many patients can experience lasting relief and maintain these improvements for several years after surgery.

In fact, a prospective randomized FDA trial found positive long-term results in patients who had two-level cervical disc replacement. At 10 years, the overall success rate was 80.4%, and the treated levels continued to maintain movement. Similarly, a 7-year randomized FDA trial involving 599 patients found significant improvements in neck disability and neck and arm pain after disc replacement. More than 95% of disc replacement patients reported being very satisfied with their treatment at seven years.

How Soon Can You Return to Normal Activities?

According to our experience, most patients can return to basic daily activities within about two weeks after cervical disc replacement. Walking can usually begin earlier, while heavier activities require more recovery time. A 2025 expert consensus study found that patients could generally return to basic daily activities and desk work within two weeks after surgery.

Activities that may require more recovery time include:

• Heavy lifting or carrying
• Repetitive overhead work
• Running or high-impact exercise
• Weight training at the gym
• Strenuous pushing or pulling
• Activities requiring sudden neck movements
• Physically demanding work or manual labor

Can You Return to Sports After Surgery?

Yes, you can return to sports after cervical disc replacement surgery, but the timing depends on the sport and your recovery. Your surgeon will check your strength, neck movement, and neurological function before allowing you to return. A safer return to sports also depends on whether the treated level remains stable and your symptoms have improved without new nerve problems.

Research also shows that many athletes return to their sport successfully after cervical disc replacement. For example, a systematic review of 57 athletes found that all returned to sports after surgery. On average, athletes returned to training at about 10 weeks and competition at about 30 weeks.

Are There Long-Term Restrictions After Disc Replacement?

No, many patients do not have permanent activity restrictions after cervical disc replacement once they have fully recovered. Because the procedure is designed to preserve movement, many patients gradually return to regular work, exercise, and daily activities. However, high-impact or contact activities may still require individual clearance from your surgeon.

While permanent restrictions are rare, your surgeon may advise you to follow certain precautions to protect your cervical spine and artificial disc, including:

• Use proper form when lifting heavy objects
• Avoid sudden increases in lifting or training intensity
• Use proper technique during strength training
• Avoid repeated movements that cause neck pain
• Wear appropriate protective equipment during contact sports
• Maintain good neck and upper-back strength
• Report new arm pain, numbness, or weakness
• Attend follow-up visits to monitor the treated level
