What does it mean to have cervical artificial disc surgery?

In place of a fusion. This is done in place of a fusion to maintain the motion at that level of the spine in the hopes of preventing the adjacent disc levels from getting too much stress on them leading to degeneration with possible disc herniation and/or spinal stenosis developing at those disc levels.
Consult with surgeon. Consult with your surgeon about the procedure and the risk and benefit of the procedure and whether there are alternative treatments. Good luck. Wishing you the best.
