Healthy spinal discs provide a cushion and a joint between your adjacent vertebrae. When your discs deteriorate, the space between the vertebrae narrows, compressing and pinching nearby nerves.
To relieve the pain and discomfort caused by the compression, a surgeon can remove and replace the collapsed or herniated disc with an artificial disc that mimics a healthy disc — providing both cushion and joint. The replacement and rebuilding of the joint with an artificial disc is termed cervical disc arthroplasty or cervical artificial disc replacement.
Cervical artificial disc replacement is a type of joint replacement procedure. An artificial disc, such as the Prestige LPTM cervical disc made by Medtronic, is placed between two adjacent cervical vertebrae to replace a diseased cervical disc. It is designed to maintain the distance between two adjacent cervical vertebrae. Two Prestige LP cervical discs can be used to replace two diseased cervical discs that are next to each other and require surgery.
DEMONSTRATION OF CERVICAL ARTHROPLASTY
Dr. Jack Zigler uses a bone model to describe cervical arthroplasty, also known as cervical disc replacement. Dr. Zigler is with the Texas Back Institute in Plano, Texas.

The Prestige LP cervical disc system has two components (a ball and trough design) that the surgeon attaches to the vertebrae on either side of the disc. These components are made of a mixture of metals commonly used in spine surgery (titanium ceramic composite) and a ceramic material (titanium carbide). The design of the Prestige LP cervical disc preserves mobility by allowing the motion (flexion, extension, side bending, and rotation) and alignment (height and curvature) of a natural disc.*
Implanting an artificial disc such as the Prestige LP cervical disc in the neck is serious surgery. The Prestige LP cervical disc is inserted very close to important nerves and blood vessels. Your doctor will be careful to find and protect these nerves and blood vessels, but there is a risk of damage to nerves or blood vessels during the surgery. A small cut to a blood vessel can cause dangerous bleeding (hemorrhage) or even death. Damage to a nerve can cause long-term loss of movement (paralysis) or feeling.
It is important that you discuss the potential risks, complications, and benefits of the Prestige LP cervical disc with your doctor prior to receiving treatment, and that you rely on your physician's judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
During cervical artificial disc replacement surgery, you will lie on your back on an operating table and be put into a deep sleep (general anesthesia). Once you are asleep, your neck area will be washed and a clean (sterile) sheet will be taped around your neck. A cut (incision) about an inch long will be made in the front of your neck and your doctor will move the structures in your neck to the side so he or she can see your spine. Your doctor will surgically remove your damaged or diseased disc and insert a Prestige LP cervical disc into the disc space. The muscle and skin incisions will be sewn together and you will be moved to the recovery room and woken up.
Cervical disc replacement surgery is major surgery requiring a hospital stay. As with any major surgery, you should expect some discomfort and a period of rehabilitation. Your doctor will outline a post-surgery recovery plan to increase your chances of a successful outcome.

At two years after surgery, considering all of the patients treated with the Prestige LP Cervical Disc at two adjacent levels, 100 out of 196 (51.0%) had more than four degrees of motion at both treated levels while bending the head forward to backward (flexion-extension).
