Artificial Cervical Disc Replacement

FDA Approved

Prestige™ Artificial Cervical Disc

The Prestige is an artificial cervical disc that is FDA approved  in the United States. It is a stainless steel metal-on-metal implant using screw fixation into the bone for immediate and permanent fixation. This cervical disc replacement device is unique compared to all other artificial cervical discs because of its ball and trough design versus a ball and socket. This allows for a coupled motion of both flexion/extension and translation. For more information on the clinical studies and FAQ please visit the Prestige website.

ProDisc-C™ Artificial Cervical Disc

The ProDisc-C Total Disc Replacement implant received FDA approval in 2007. This cervical disc replacement is composed of metal endplates on the top and bottom (cobalt chromium molybdenum) and a plastic inlay (ultra-high molecular weight polyethylene) that form a ball-and-socket joint. The ProDisc-C provides the possibility of motion by allowing the top endplate to move over the plastic ball attached to the bottom endplate. The materials used in the artificial cervical disc have been used in artificial disc replacement for more than 20 years in Europe and are the most commonly used materials in knee and hip replacements worldwide.  Learn more from the ProDisc-C artificial cervical disc website and

Mobi-C® Cervical Disc

Only FDA Approved Cervical Disc for One & Two Levels

Mobi-C® was first implanted in Europe in November 2004. To receive approval in the United States, LDR conducted an Investigational Device Exemption (IDE) clinical trial involving 599 patients that began in April 2006. This study compared Mobi-C to the current standard of care, Anterior Cervical Discectomy and Fusion (ACDF), for both one and two-level indications. Mobi-C Cervical Disc

Currently Enrolling: M6

The M6 artificial cervical disc offers an innovative option for artificial cervical disc replacement because of its unique design which is based on a natural disc’s qualities.

Engineered to replicate your own disc, the M6 is the only artificial disc that incorporates an artificial nucleus (made from polycarbonate urethane) and a woven fiber annulus (made from polyethylene). The M6 artificial nucleus and annulus are designed to provide the same motion characteristics of a natural disc.

Together, the M6’s artificial nucleus and annulus provide compressive capabilities along with a controlled range of natural motion in all 6 degrees of freedom along each vertebra. This “natural” motion is designed to provide the freedom to move your neck naturally.

The M6 has two titanium outer plates with keels for anchoring the disc into the bone of the vertebral body. These outer plates are coated with a titanium plasma spray that promotes bone growth into the metal plates, providing long term fixation and stability of the disc in the bone.
