Study DesignA retrospective cohort utilizing the PearlDiver Patient Claims Database.ObjectiveCervical disc arthroplasty (CDA) is accepted treatment for cervical radiculopathy
however, it may also be safe and effective in myelopathy. Thus, we compared clinical characteristics and outcomes in patients undergoing CDA and anterior cervical discectomy and fusion (ACDF) for degenerative cervical myelopathy (DCM) specifically.MethodsPatients undergoing CDA or ACDF between 2015-2019 were identified with follow-up through 2021. Univariate and multivariable analyses were performed to identify factors associated with either procedure. Reoperation rates were compared using propensity-matched analysis.ResultsWe identified n = 2391 CDA and n = 50 845 ACDF procedures for DCM. Factors favoring CDA included: female sex, younger age, lower CCI, lower incidence of obesity, osteoporosis, diabetes, or smoking (
