Re: artificial cervical disc
From an article on Adjacent Disk Syndrome...
""" Clinically, long-term deterioration after ACDF has been documented in several studies. Hilibrand, et al., studied 374 patients who had undergone anterior cervical fusion and reported that adjacent-segment degeneration with new radiculopathic symptoms occurred in 2.9% of them per year, with a cumulative rate of 25% in a 10-year period. Two thirds of these patients required additional cervical fusion surgeries."""
What does that tell you?
