Zero-profile versus cage-plate interbody fusion system in anterior cervical discectomy and fusion for the treatment of multilevel cervical spondylosis: A protocol of systematic review and meta-analysis

Abstract

Background:The objective of this meta-analysis was to summarize and identify the available evidence from these studies to estimate which device was better for multilevel cervical spondylotic myelopathy (MCSM). And provides clinicians with evidence on which to base their clinical decision making.Methods:This review will include all studies comparing the new Zero-profile versus cage-plate interbody fusion system in anterior cervical discectomy and fusion (ACDF) for the treatment of MCSM. The search strategy will be performed in 9 databases. We will not establish any limitations to language and publication status, published from inception to the July, 2020. Two reviewers will screen, select studies, extract data, and assess quality independently. Outcome is operative time, blood loss, clinical function outcome, radiologic outcomes, and complications. The methodological quality including the risk of bias of the included studies will be evaluated. We will carry out statistical analysis using RevMan 5.3 software.Results:This study will summarize current evidence to assess the efficacy and safety of Zero-profile versus cage-plate interbody fusion system in ACDF for the treatment of MCSM.Conclusion:The findings of this study will provide helpful evidence for the clinician, and will promote further studies, as well as comparing the 2 devices in ACDF for MCSMRegistration number:INPLASY202070095 (DOI number: 10.37766/inplasy2020.7.0095).
