I'm thinking about having a disc replacement for a worn out L4/5 disc. I know there are several different artificial discs on the market. Do they come in different sizes (small, medium, large), too?
Researchers have been working on an artificial disc replacement (ADR) for many years. Finally, the technology is available to give us several ADRs to choose from. ProDisc II, Link SB Charité III, and the Maverick disc systems are three examples of ADRs on the market.
The implants do come in several sizes. Each one angles the low back slightly differently. The disc height also changes with different dimensions of the disc plate. The goal is to restore normal motion and stability at the segment or level of repair. Properly working facet joints in the back of the spine are also needed for normal spinal motion.
