The rate, risk factors and consequence of adjacent level disease (ALD) in cervical disc arthroplasty (CDA) remains unclear. The purpose of this study is to determine the rate, risk factors and clinical outcome of ALD in CDA.

Methods: Retrospective review of 166 patients with a minimum five-year follow-up of a CDA was performed. Multi-level surgeries, including hybrid procedures, were included.
