Artificial Disc Replacement


ARTIFICIAL DISC REPLACEMENT
Some of the greatest advancements in spine technology are available at Texas Back Institute. The replacement disc technologies offered through Texas Back Institute are many and varied, which gives your physician options when considering the type that may be best for you. Replacement discs can help relieve pain and restore motion. And they have proven more effective than fusion surgery in getting desired results.
Physicians at Texas Back Institute have worked as clinical investigators on ProDisc-C, Mobi-C Single Level, and Mobi-C Two Level. We have also been investigators on several other cervical discs that are not yet FDA-approved. These include Simplify Disc Single Level, Simplify Disc Two Level, M-6 Single Level, Discover Disc, and Kineflex.
The Mobi-C cervical disc is one of the most widely used cervical discs in the world. First implanted in Orleans, France in November 2004, Mobi-C has been implanted in more than 17,000 spinal levels in 25 countries. It is the only FDA Approved Cervical Disc for One & Two Levels and is superior to fusion for two-level disc replacement.
How the Mobi-C Works
Mobi-C contains patented Mobile Core Technology™ that allows the polyethylene core to slide and rotate inside the disc for self-adjustment to the cervical spine movements. This means that Mobi-C can react to the normal motion in the cervical spine.
Mobi-C provides bone sparing fixation without chisel cuts into the small vertebral bodies of the cervical spine, making it safe for implantation at two levels.


ProDisc is a Total Disc Replacement (TDR) technology platform that offers a surgical alternative to spinal fusion. Qualified patients generally suffer from a single-level degenerated disc in the upper (cervical) or lower (lumbar) spine. ProDisc implants are intended to relieve pain while allowing the potential for motion at the diseased spinal segment. Synthes Spine is currently the only company in the United States to offer Total Disc Replacement devices for both the upper and lower spine.
ProDisc L: Total disc replacement for the lower (lumbar) spine (L3-S1)
The ProDisc-L Total Disc Replacement device is intended to treat a single degenerated (diseased) disc in the lower spine (L3-S1). The ProDisc-L implant was designed in collaboration with practicing spine surgeons and has been thoroughly tested in both laboratory and clinical settings.
Motion
The ProDisc-L implant allows the potential for motion through its ball and socket design:
- A plastic inlay affixed to a bottom metal endplate forms the ball.
- A polished concave metal surface in the top endplate forms the socket.
- The socket can move over the surface of the ball to allow for controlled and predictable motion.


Fixation
The ProDisc-L implant is secured to the bones (vertebrae) in the spine with a patented central keel on the top and bottom endplates. A coating has also been applied to all the implant surfaces that contact bone to allow for the bone to grow onto the implant.


Total Disc Replacement surgery with ProDisc is different from traditional spinal fusion surgery. Both surgeries are intended to relieve pain by removing the diseased disc and restoring the height of the affected disc space.
The ProDisc-C Total Disc Replacement device is intended to treat a single degenerated (diseased) disc in the upper spine (C3-C7). The ProDisc-C implant was designed in collaboration with practicing spine surgeons and has been thoroughly tested in both laboratory and clinical settings.

The ProDisc-C was developed using the same design principles as the ProDisc-L implant. The first ProDisc-C Total Disc Replacement surgery was performed in Europe in 2002. It was approved by the Food and Drug Administration (FDA) for use in the United States in December 2007.
