Medtronic Mobi-C ® Cervical Disc

Content Contributor

Medtronic Mobi-C technologies utilize a metal on polyethylene joint interface. The most recent cervical disc replacement device to be FDA approved is the Prestige© LP, which features metal on ceramic. Current studies show that the performance of these artificial discs is rather uniform, with none demonstrating clear superiority.

The Mobi-C features a mobile bearing design between the polyethylene insert and the inferior baseplate (meaning the polyethylene can rotate on top of the base plate). The Mobi-C metal endplates also do not feature the keels as do the Prodisc-C and relies more on the bone-plate interface for fixation. This has not shown to have an impact on patient outcomes to date.
