PCM Cervical Disc is designed to replace the diseased disc, providing support for the vertebrae while allowing for movement of the joint.We are not sure if it is still on the market due to the acquisition of NuVasive by Globus.
The PCM Cervical Disc which stands for Porous Coated Motion consists of the following parts: an upper metal (cobalt chromium molybdenum alloy) endplate, and a lower metal endplate to which a plastic (polyethylene) spacer is attached. These materials are the same as the ones used for most spinal and orthopedic devices. Several device sizes are available to best fit the disc space. The superior and inferior endplates also feature three rows of “V-Teeth” which provide short-term fixation until long-term fixation can occur to anchor our motion preserving device.

I think I would be too afraid to get a spinal fusion because of the loss of motion. I may go with the artificial disc replacement. It seems like a better option for me and would make me less stressed about the surgery.
