Discover cervical disc

The Discover cervical disc was developed by DePuy Spine (Rayham, Massachusetts, USA) (Figure 12.13). This artificial disc is a fixed bearing, with a convex Ti alloy end-plate articulating on a UHMWPE convex inferior core. The core is affixed to the inferior endplates. Bone fixation is achieved by a combination of a textured Ti surface and teeth. The Discover is clinically available in Europe but is not expected to receive clearance by the FDA until 2011.

In this section, we summarize the design features and available literature for contemporary cervical metal-on-UHMWPE artificial discs. Many cervical disc replacements have been proposed over the years, but today five contemporary designs have been documented in the peer-reviewed literature and are currently in chnical trials in the United States ProDisc-C, PCM, Mobi-C, and Discover (Table 12.5). As detailed in the table, these designs differ from each other in several respects, including the philosophy as well as the constraint in the bearing (Table 12.5).
