What is Cervical Disc Replacement?
Cervical disc replacement, also called artificial disc replacement or total disc replacement, is a surgical procedure where a damaged disc in the neck is removed and replaced with an artificial disc. Unlike fusion surgery, disc replacement preserves motion at that segment of your spine.
The artificial disc is designed to mimic the function of a natural, healthy disc, allowing you to maintain neck flexibility while eliminating the source of pain. This motion-preserving approach may reduce stress on adjacent spinal segments and potentially lower the risk of adjacent segment degeneration.
Dr. Rastegar performs this procedure through a small incision in the front of the neck (anterior approach), using advanced imaging and surgical techniques for optimal placement and outcomes.
When is Cervical Disc Replacement Recommended?
Cervical disc replacement may be appropriate if you have:
- A single-level herniated disc in the neck causing arm pain or weakness
- Degenerative disc disease in the cervical spine
- Symptoms that haven't responded to conservative treatment
- Good bone quality and overall spine health
- No significant spinal instability or arthritis at the affected level
Note: Not all patients are candidates for disc replacement. Dr. Rastegar will evaluate your specific condition to determine if disc replacement or fusion is the better option for you.
Advantages Over Fusion
- Preserves Neck Motion: Maintains natural movement at the treated level
- May Reduce Adjacent Segment Stress: Maintaining motion may lower risk of degeneration at neighboring levels
- Faster Return to Activities: No fusion healing time required
- Similar Recovery Time: Recovery comparable to or faster than fusion
- No Bone Graft Needed: Eliminates concerns about graft harvest site pain
Recovery Timeline
Hospital Stay
Most patients stay overnight and go home the next day. Some may qualify for same-day discharge.
First 2 Weeks
Light activities and walking. A soft collar may be worn for comfort. Avoid heavy lifting and strenuous activities.
Weeks 2-6
Gradual increase in activities. Physical therapy begins. Return to desk work is often possible.
6-12 Weeks
Return to most normal activities including driving and light exercise. Follow-up imaging confirms proper positioning.
Frequently Asked Questions
How long does an artificial disc last?
Artificial discs are designed to last many years, potentially a lifetime. Long-term studies show excellent durability and sustained motion preservation. Regular follow-up ensures the device is functioning properly.
Can I have an MRI after disc replacement?
Most modern artificial discs are MRI-compatible, though the metal may cause some artifact on images. Dr. Rastegar uses MRI-friendly devices whenever possible and will discuss this during consultation.
Disc replacement vs. fusion: which is better?
Both procedures are effective. Disc replacement preserves motion, which may benefit younger, active patients with single-level disease. Fusion is better for cases with instability, multiple levels, or significant arthritis. Dr. Rastegar will recommend the best option for your specific situation.
