Loidolt T, Kurra S, Riew KD, et al. - In this study, the 10-year follow-up adverse events rates between cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF) were explored. Researchers randomized, prospective, multicenter Investigational Device Exemption (IDE) trial and its continued follow-up as a postapproval study (PAS) to conduct single-level surgeries for cervical disc pathologies between May 2002 and October 2004. A total of463 patients were included in the study (a total of 242 patients received CDA and 221 patients received ACDF). The outcomes of this study demonstrate that cumulative rates of patients who had any adverse events were not different between the artificial cervical disc and the anterior cervical arthrodesis groups. Between the two groups, the cumulative rates were not different for the majority of categories as well.
