Cervical Disc Replacement

Visit our Specialty Center

Cervical disc replacement is an advanced surgical procedure designed to relieve nerve or spinal cord compression in the neck while preserving natural spinal motion. Instead of fusing the vertebrae together, as in traditional anterior cervical fusion (ACDF), this procedure replaces a damaged disc with an artificial disc implant that maintains movement at that level of the spine.

At New Jersey Brain and Spine, cervical disc replacement may be recommended for patients with persistent neck pain, arm pain, numbness, or weakness caused by conditions such as herniated discs or cervical spinal stenosis. For appropriately selected patients, artificial disc replacement offers effective decompression while reducing stress on adjacent spinal levels.

What Is Cervical Disc Replacement?

Cervical disc replacement, which is also known as artificial disc replacement, is a procedure in which a damaged cervical disc is removed and replaced with a medical-grade artificial implant designed to mimic the natural motion of the spine.

Neck discomfort and cervical radiculopathy (nerve-related arm pain) are widespread conditions that affect a significant portion of the population. In fact, research shows that up to 40% of work absenteeism can be traced to people who have a history of neck pain. Cervical disc replacement has become an increasingly common alternative to fusion for patients with single-level disc disease who do not have significant spinal instability. Clinical studies have demonstrated comparable or improved outcomes in carefully selected patients, particularly in preserving range of motion.

Unlike fusion surgery, which permanently connects two vertebrae, disc replacement maintains mobility at the treated level, potentially reducing long-term stress on adjacent discs.

How Is Cervical Disc Replacement Performed?

Cervical disc replacement is performed under general anesthesia using an anterior (front-of-the-neck) approach, similar to ACDF surgery.

During the procedure, the surgeon:

• Makes a small incision in the front of the neck;
• Removes the damaged disc;
• Relieves pressure on the spinal cord and/or nerve roots; and then
• Places an artificial disc implant into the disc space.

The procedure typically takes one to two hours. Most patients are discharged the same day, or some may stay overnight. Because motion is preserved, many patients experience a relatively smooth recovery, returning to light activities within two to four weeks. As always, recovery timelines can depend on individual factors.

When Is Cervical Disc Replacement Recommended?

Cervical disc replacement is typically recommended when:

• A single cervical disc is causing nerve compression
• Symptoms include arm pain, numbness, or weakness
• Conservative treatment has failed
• There is no significant spinal instability or advanced arthritis
• There is no significant cervical deformity

For some patients, cervical disc replacement may be preferred over anterior cervical fusion (ACDF) because it preserves motion and may reduce adjacent segment degeneration over time.

What Patients Are Good Candidates for Cervical Disc Replacement?

Patients who may be good candidates include those who:

• Have a single-level cervical disc herniation
• Experience arm pain caused by nerve compression
• Have not improved with non-surgical treatment
• Do not have significant cervical instability
• Are focused on maintaining neck mobility
• Have maintained neck alignment
• Do not have significant bone spurs
• Neck pain is not their main complaint rather than arm pain

Our team at New Jersey Brain and Spine includes board-certified neurosurgeons with expertise in both fusion and motion-preserving spine procedures. Because we are a practice focused on subspecialization, our patients benefit from spine experts who always start with the most conservative treatment option and answer any and all patient questions along the way. 

Risks and Benefits of Cervical Disc Replacement

Cervical disc replacement offers a motion-preserving alternative to fusion, but as with any surgery, risks and benefits must be carefully considered.

Potential Benefits:

• Preservation of natural neck motion
• Relief of arm pain and nerve symptoms
• Reduced stress on adjacent spinal levels, and therefore less adjacent segment breakdown that would require additional surgery
• Comparable success rates to fusion in appropriate candidates

Potential Risks:

• Infection or bleeding
• Implant-related complications
• Nerve or spinal cord injury
• Need for future surgery
• Persistent neck pain

Your neurosurgeon will review your imaging, symptoms, and overall spinal health to determine whether disc replacement or fusion is the best option. 

Case Study: Successful Cervical Disc Replacement

A 45-year-old patient presented to New Jersey Brain and Spine with persistent neck pain and radiating arm symptoms caused by a single-level cervical disc herniation. After conservative therapy failed to provide relief, imaging confirmed nerve compression, due to a soft disc herniation, without spinal instability.

Because the patient was young and active, the NJBS team recommended cervical disc replacement to preserve spinal motion. Following surgery, the patient experienced rapid improvement in arm pain and returned to work within weeks. At the one-year follow-up, the patient maintained full range of motion and reported sustained symptom relief.
