Treatment of Single-Level Cervical Spondylosis: Cervical Disk Arthroplasty Versus Anterior Cervical Decompression and Fusion.

A meta-analysis was performed to compare cervical arthroplasty with anterior cervical diskectomy and fusion for single-level cervical spondylosis. A comprehensive search was conducted with PubMed, Embase, and the Cochrane Central Register of Controlled Trials from January 1, 2000, to April 30, 2015. Random-effects models were used for heterogeneous data. Fixed-effects models were used for pooled nonheterogeneous data. Mean difference or standard mean difference was used for continuous outcomes, and odds ratio, risk ratio, or risk difference was used for dichotomous outcomes. [Orthopedics. 2017; 40(1):e23-e34.].
