Cervical Disc Arthroplasty Usage has Leveled out from 2010 to 2021.

While the use of CDA relative to ACDF rose from 2010 to 2018, its use has subsequently plateaued between 2018 and 2021 and remained a relatively low percent of the single level anterior cervical surgeries performed (14.47% in 2021). Causes for such changes in trend are unclear.
