Abstract
BACKGROUND: The goal of this meta-analysis is to explore the overall efficacy as well as the safety of anterior versus posterior approach for the therapy of patients with multilevel cervical spondylotic myelopathy based on qualified studies. METHODS: Three electronic databases, PubMed, Cochrane, Embase were searched updated to January 2018 to identify all relevant and qualified studies using the index words. The qualified studies were including prospective or retrospective comparative studies. Relative risk (RR) and mean difference (MD) along with 95% confidence interval (95% CI) were used to analyze the main outcomes. RESULTS: In this meta-analysis, there were a total of 24 studies with 959 patients in the anterior approach group and 1072 patients in the posterior approach group. The final results showed, in comparison of the posterior approach group, the anterior approach group significantly increased the JOA score (SMD: 0.36, 95% CI 0.10-0.62), the operation time (WMD: 49.87, 95% CI 17.67-82.08), and the neurological recovery rate (WMD: 10.55, 95% CI 3.99-17.11) with higher complication rate (RR: 1.53, 95% CI 1.24-1.89). Besides, there was no significant difference of the blood loss (SMD: - 0.40, 95% CI - 1.12 to 0.32) and ROM (SMD: - 0.28, 95% CI - 0.78 to - 0.22) between posterior approach group and anterior approach group. CONCLUSIONS: Studies found a significant increase of JOA score as well as neurological recovery rate by the anterior approach treatment when compared with posterior approach treatment. However, increased operation time and complications could also occur through the anterior approach treatment. More high-quality randomized controlled trials with larger sample size, multi-centric and longer follow-ups are needed to support our current conclusions.
