Spinal Surgery

Cervical Disc Replacement

Artificial cervical disc replacement involves a surgical procedure during which a damaged intervertebral disc in your neck is replaced with a man-made disc. Disc replacement is an alternative to spinal fusion for some patients.

Unlike cervical spine fusion that permanently joins two vertebral bodies and stops motion at that level, an artificial disc mimics the movement of a human intervertebral disc. Some of the benefits of a artificial cervical disc replacement include:

It preserves motion
It restores lost disc height
It stabilizes the cervical spine
It bears the weight of your head at rest and during movement
Shares stress during movement with intervertebral discs above and below

Cervical artificial discs

The construction of an artificial disc usually combines hard and soft materials, such as stainless steel and polyethylene. The artificial disc may be secured in place using bone screws. Some designs have spike-like surfaces that grip to the upper and lower surfaces of the vertebral bodies.

Surgical recommendation

Keep in mind, most patients with neck and/or arm pain do not need spine surgery, spinal fusion, or disc replacement. Your neurosurgeon may consider spine surgery (with or without fusion or disc replacement) when …

Non-surgical treatments, such as medication, physical therapy and/or spinal injections do not control pain and other symptoms
Nerve-related symptoms such as weakness, numbness, tingling sensations involve the arm(s) and/or leg(s)
Pain and symptoms are progressive and become worse
It is difficult to walk
You have problems with balance
Your general health is good
You have no signs of arthritis, infection, osteoporosis (or other bone disease)
You are not allergic to stainless steel

Are you a candidate?

Your neurosurgeon knows if cervical artificial disc replacement is an option for you and explains why. If he recommends disc replacement, he educates you about the type of artificial disc, and benefits and risks associated with the device and the surgical procedure.

Your risks and complications may be different from those of another patient because you are unique. Your neurosurgeon takes that into serious consideration and thoughtfully explains potential risks to you, which may include infection, bleeding, reaction to anesthesia, and nerve damage.

Before your procedure

Before surgery, you visit your primary care doctor or general practitioner to obtain a general health clearance. This means your doctor has carefully evaluated your health in terms of undergoing surgery. Your assessment may include blood tests, x-rays or other imaging studies, as well as special tests for existing medical problems (i.e., diabetes, heart disease).

Surgical information

Artificial cervical disc replacement surgery is performed under general anesthesia. The procedure is similar to anterior cervical discectomy and fusion. Throughout your procedure, the neurosurgeon and his surgical team are kept current about your vital functions, including your central nervous system. Many different gauges, monitors, and equipment provide visual and audio feedback to the surgical team. Image guidance (real time x-ray; fluoroscopy) allows your neurosurgeon to see other views of the surgical field during (intra-operative) your procedure.

Basic surgical steps

You are positioned face up on a padded operating table
Real time x-rays are taken to confirm the cervical level
Your neurosurgeon makes an incision in front of your neck. The skin incision may be made through one of the natural folds of your neck. This helps to disguise scarring
Muscle and other soft tissues are gently pulled aside to expose the intervertebral disc*
A discectomy is performed to remove the entire disc
The disc space and endplates are prepared to receive the artificial disc
If necessary, the spinal cord and/or nerve roots are further decompressed by trimming away bony overgrowths (bone spurs, osteophytes), thickened ligament and/or other tissues
The components of the artificial disc are implanted, and one or more intra-operative x-rays confirm the device is properly seated between the vertebral bodies
The incision is closed and dressed

*This is typical of a minimally invasive surgical technique wherein muscles and soft tissues are not cut.

After surgery

You are moved from the operating room into the recovery area. Here, the nurses and medical staff closely monitor your vital signs with attention to managing post-operative pain. You should expect some discomfort. You may have pain at the incision site, occasional neck muscle spasms, or other symptoms.
