An artificial disc is a device that is implanted into the spine to replace a degenerative disc, whose regular function is to carry weight and allow motion. A disc is the soft cushioning structure between the individual bones of the spine, (called vertebra).
Artificial discs are usually made of metal and plastic-like (biopolymer) materials, or a combination of the two. These materials have been used in the body for many years.
The reasons for choosing to replace a disc may vary for each condition. Generally, if the pain caused by the affected disc has not been reduced enough with non-surgical treatments, such as medication, injections, or physical therapy, a doctor may suggest disc replacement.
Currently, Artificial Disc Replacement is considered experimental and is not approved by the Food and Drug Administration (FDA). Most of the research that has been conducted on artificial discs has been carried out in
In addition to the potential complications associated with undergoing surgery and general anesthesia, the complications associated with artificial disc replacement may include breakage of the metal plate, dislocation of the implant, and infection. To help minimize complications associated with the implant itself, proper selection of patients and size of implant is very important.
Finally, like joint replacement surgery, artificial implants may fail over time due to wear of the materials and loosening of the implants. Therefore, long term studies that track the life span of the implants are needed.
