Cervical Disc Replacement

What is cervical disc replacement?

Cervical disc replacement removes a damaged disc from the neck and replaces it with an artificial disc designed to allow movement at that level. It is also called cervical disc arthroplasty. The surgeon first relieves pressure on the nerves or spinal cord; the implant then supports the space between the vertebrae while permitting controlled motion.

Disc replacement and ACDF can address some of the same symptoms, but they accomplish stabilization differently. Preserving movement is useful only when the surrounding joints, bones, and alignment can support it. The best operation is the one that fits your anatomy and diagnosis.

When might it help?

Disc replacement may help selected patients with cervical disc herniation or degenerative disc disease causing arm pain, numbness, or weakness. Some patients with spinal cord compression may also be candidates, depending on the extent and location of their disease.

Persistent nerve-related symptoms

Pain traveling into the shoulder, arm, or hand can interfere with sleep, work, and exercise. If appropriate nonsurgical care has not provided enough relief, removing the compressive disc may be considered. Progressive weakness or changes in walking and hand coordination need prompt assessment.

A segment that can still move well

The treated level needs suitable alignment, bone quality, and supporting joints. Advanced facet arthritis, marked instability, severe collapse, or poor bone quality may favor a different approach. The number of levels and the specific implant’s indications also matter.

Choosing between replacement and fusion

Dr. Jalali will review your examination, MRI, and X-rays, including motion studies when helpful. ACDF or posterior decompression may be a better fit in some cases. Disc replacement does not promise normal neck motion or prevent every future spinal problem.

Defining meaningful improvement

The goal is relief of symptoms from the treated level and a return toward your usual activities. Longstanding numbness or weakness can persist despite adequate decompression. Isolated neck pain without a clear treatable cause requires particular care in deciding whether surgery is appropriate.

RELATED CONDITIONS

What happens during surgery?

Under anesthesia, an incision at the front of the neck provides access to the affected disc. The disc and compressive bone spurs are removed, and the nerve openings and spinal canal are assessed. The surgeon prepares the space and places an artificial disc sized to your anatomy.

Implant selection and positioning

Different implants have different designs and eligibility criteria. Imaging helps check the position during surgery. The discussion before surgery should cover the planned levels, why replacement is suitable, and whether findings could require a change in plan.

Recovery is a gradual return to activity.

Walking generally begins early. Some patients return home the day of surgery; others need an overnight stay. Temporary throat discomfort, swallowing difficulty, or hoarseness can occur after an anterior approach.

Work, driving, exercise, and physical therapy progress according to your symptoms and follow-up findings. There is no fusion to wait for at the replaced level, but the surgical tissues still need time to heal. Avoid treating early pain relief as clearance for unrestricted lifting or sport.

Understand the tradeoffs.

Risks include infection, bleeding, nerve or spinal cord injury, swallowing or voice problems, implant migration or wear, and persistent symptoms. Bone can develop around the implant and restrict motion. Further surgery, including conversion to fusion, may be necessary.
