What are artificial discs?
As the name suggests, artificial discs resemble normal human discs. Healthy human discs serve as a cushion between the spinal vertebrae, and absorb stress and shock from movement, and protect the vertebrae from grinding against one another. These intervertebral discs degenerate as part of the normal aging process. As they degenerate, the discs may flatten, which can cause nerve impingement, inflammation, and pain. Disc degeneration can also cause pain as the vertebral bones begin to press against one another. This pain is increased by motion, such as bending, twisting and lifting.
Artificial discs are designed to fit into the damaged disc space in order to restore disc height, improve mobility and flexibility, and eliminate pain. There are several types of artificial discs. The discs are made of surgical grade metal (such as stainless steel or titanium). Some also include a soft, pliable inner material made from polyethylene.
Why are they used?
Degenerative disc disease is a common ailment that affects 40-50% of the over-40 population. Disc degeneration is usually treated with non-operative care, such as bed rest, pain management, and physical therapy. However, when conservative treatments fail, patients with severe degenerative disc disease may need fusion surgery to increase stability and strength, restore height, and reduce pain. This type of surgery involves removing the degenerated disc, harvesting small pieces of the patient's own bone (taken from other parts of the body, such as the hip) and using it to fuse together damaged vertebrae. The procedure may also include the use of special spinal instrumentation to help facilitate the fusion.
The use of artificial discs may be an alternative to fusion surgery. Instead of removing discs and fusing vertebrae together, the damaged discs will simply be replaced with artificial discs. Recent developments mean that both lumbar artificial discs and cervical artificial discs are now in use.
