PCM Cervical Disc is designed to replace the diseased disc, providing support for the vertebrae while allowing for movement of the joint.
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.
About Artifical Cervical Disc
An artificial cervical disc is a device inserted between two vertebrae in the neck to replace a damaged disc.The intent of the artificial disc is to preserve motion at the disc space. It is an alternative to the commonly performed anterior cervical discectomy and fusion (ACDF), a surgical procedure that is designed to address the pathology by eliminating motion at the diseased disc level.Artificial disc replacement (ADR) surgery—also known as a total disc arthroplasty or total disc replacement (TDR)—is typically performed for a patient with a cervical disc herniation that is causing significant neck pain and/or arm pain that has not responded to nonsurgical treatment options and is significantly affecting the individual’s quality of life and ability to function.Source:https://www.spine-health.com

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.
