The BRYAN Cervical Disc is composed of a plastic (polyurethane) center with titanium endplates. It is designed as a one-piece device that allows unconstrained motion.

The Bryan cervical artificial disc is unique in that there is a flexible membrane that surrounds the nucleus (the inner portion of the disc) that is filled with a lubricant. This membrane is designed for two purposes: to contain any wear debris that forms and to prevent any soft tissue in-growth. This disc is designed to allow a normal range of motion of the neck.


As of May 2009, the BRYAN Cervical Disc is approved by the FDA for commercial distribution in the US.1 FDA clinical trials have currently reported 4-year results.2
