Artificial Disc Replacement: Overview, Advantages, & Eligibility Criteria
Our intervertebral discs are crucial to the performance of our spine and, when damaged, can result in debilitating pain or side effects. For damaged cervical or lumbar discs, a minimally invasive artificial disc replacement aims to relieve spinal pain and dysfunction by replacing the damaged intervertebral disc. These prosthetic replacements are designed to mimic our natural discs by maintaining the height between our vertebrae, providing a shock absorbing cushion, and allowing for the fluid movement of our spine.
Artificial disc replacements can be engineered differently, but the most commonly used model is made of a plastic-like material called a biopolymer. This particular material mimics the rubbery texture of your body’s intervertebral discs. The biopolymer is sandwiched between two metal plates that allow for stable attachment to adjacent vertebrae.
During a minimally invasive Artificial Disc Replacement, your surgeon will make a small incision, typically on the front (or anterior) side of the body. An anterior approach allows for a clearer visual of, and complete access to, our intervertebral discs, which are shielded from view on the posterior side by bones, muscles, and critical nerves, including the spinal cord. Through this anterior approach, organs and tissues are gently pushed to the side, and the damaged disc is removed using small, specialized tools and advanced techniques. To maintain the vertebral height, the disc replacement is implanted and attached to the two adjacent vertebrae. The surgery is concluded with returning organs and tissues to their rightful positions and closing the incision.
Advantages of an Artificial Disc Replacement
Artificial disc replacements have provided many patients with the opportunity to return to the activities that they once enjoyed before the onset of debilitating pain. The advancements in more realistic surgical materials and better surgical techniques have led to the following benefits for patients:
- A less restrictive option when compared to traditional fusion procedures that limit mobility
- The anterior approach avoids damage to muscles, bones, ligaments, and nerves in the back
- Smaller incisions result in less pain, blood loss, scarring, and shorter recovery times
- Minimally invasive techniques allow for many patients to be up and walking after the surgery
- Many patients experience full or mostly restored mobility in their vertebrae following surgery

Eligibility Requirements for an Artificial Disc Replacement
Complete replacement of a spinal disc without the need for fusion is a condition-specific procedure that can help individuals who suffer from particular types of pinched nerve pain. If you meet this criterion and have not found relief from more conservative treatments like physical therapy or pain management, then an artificial disc replacement may be a valuable, state-of-the-art option to relieve your pain. Most candidates for an artificial disc replacement will be between the ages of 18 and 60; have only one disc that requires replacement; and exhibit signs of radiculopathy, or pain that shoots from the site of nerve impingement and into the limbs.
Because an artificial disc replacement is a specialized option indicated only for specific spine conditions, there may be certain situations that could disqualify you from receiving this procedure. If you are pregnant or have more than one compromised vertebral disc, a spinal infection (or osteomyelitis), spinal stenosis, osteoporosis, spondylolisthesis, or another severe form of spinal instability, then an artificial disc replacement may not be recommended for you.
