Artificial Disc Replacement
Replacing a worn disc to improve spine function
Artificial disc replacement is a surgical method of replacing the diseased or damaged intervertebral discs of the spinal column with an artificial disc to restore motion to the spine.
It can be considered as an alternative to spinal fusion for patients with back pain.
artificial disc replacement frequently asked questions
What does Artificial disc replacement involve?
During the surgery, an incision is made in the abdomen, and the muscles and the blood vessels are gently moved apart for better view and room for surgery. The disc space is opened and the damaged disc is removed and replaced with the artificial disc.
Artificial disk designs are of two types, disc nucleus replacement and total disc replacement.
With the disc nucleus replacement only the central portion of the disc (nucleus) is removed and replaced with mechanical device, while the outer ring of the disc (annulus) is not removed. However disc nucleus replacement procedure is not commonly practiced and is in investigative stage. In total artificial disk replacement, the annulus and nucleus are replaced with the mechanical device to restore normal spinal function. Artificial discs are usually made up of metal, plastic or a combination of metal and plastic. Medical grade plastic (polyethylene) and medical grade cobalt chromium or titanium alloy are used for disk design.
What are the benefits and risks of Artificial disc replacement?
Artificial disc replacement surgery may cause certain complications and they include:
- Infection
- Injury to blood vessels
- Dislodgement or breakage of the device
- Wear of the device materials
- Continued or increasing pain
- Bleeding
- Bladder problems
How do i prepare for Artificial disc replacement?
Your doctor may recommend certain tests such as, magnetic resonance imaging (MRI), discography, computed tomography (CT or CAT scan), and X-rays to identify the cause of pain. Patients with back pain caused from bulged or worn out intervertebral disks and patients with no significant facet joint disease are recommended for artificial disc replacement. The surgery is not recommended in patients with scoliosis, previous spinal surgery and morbidly obese.
What can I expect from recovery?
An artificial disk implantation does not require healing and therefore rehabilitation can be started soon after the surgery. Hospital stay of about 2 to 4 days may be required. Basic exercises including regular walking and stretching may be performed during the first few weeks after surgery.
