ProDisc-C Total Disc Replacement surgery is an alternative to anterior cervical discectomy and fusion (ACDF), which is the surgery that is most commonly done for your condition. The ProDisc-C Total Disc Replacement implant is composed of top and bottom metal (cobalt chromium molybdenum) endplates and a plastic inlay (ultra-high molecular weight polyethylene) that form a ball and socket joint. The ProDisc-C Total Disc Replacement implant provides the possibility for motion by allowing the top endplate to move over the plastic ball attached to the bottom endplate. The materials used in the ProDisc-C Total Disc Replacement implant have been used in spinal disc replacement for over 20 years in Europe and are the most commonly used materials in knee and hip replacements worldwide.
