While artificial discs are fairly new to the U.S. market, with the first disc gaining approval in late 2004, they have been in existence and used for years in other parts of the world such as Europe. Encouraged by the modest benefit to patients, companies have begun to introduce these first-generation devices in the United States. However, these designs use materials and technology invented more than 20 years ago.

While these discs have done a wonderful job of helping surgeons to help patients live better, more productive lives, medical technologies are continuing to advance and the next evolution in artificial disc are beginning to emerge in clinical studies in the United States. These new devices more closely mimic anatomical motion, utilize the latest materials available, and improve on implant safety. The mobile inserts within the Mobidisc^® and Mobi-C^® discs are examples of these second generation technological advances.

Looking ahead, third-generation and fourth-generation devices may further refine disc designs or incorporate new, novel biologic materials. Research continues for smarter methods of treating disc pain and other debilitating symptoms perhaps using technologies new to spine or medical devices.
