Abstract
OBJECTIVE: To compare the clinical outcomes and postoperative complications between open-door laminoplasty (ODL) versus French-door laminoplasty (FDL) for the treatment of cervical multilevel compressive myelopathy. METHODS: We comprehensively searched PubMed, EMBASE, Cochrane library, and China National Knowledge Infrastructure to identify relevant articles. The search results were last updated on January 1, 2018. All values of weighted mean difference (WMD) and odds ratio are expressed as ODL relative to FDL. RESULTS: Six studies containing 430 patients were included in our meta-analysis. In randomized controlled trials, there was no significant difference in Japanese Orthopaedic Association (JOA) scores between ODL and FDL groups (WMD, 0.06; 95% confidence limits [CL], -0.52 to 0.64; P = 0.84). However, in the retrospective trials, JOA scores were significantly higher in the ODL group than in the FDL group (WMD, 0.95; 95% CL, 0.55-1.34; P < 0.05). The pooled data showed that the magnitude of spinal canal expansion in the ODL group was higher than in the FDL group (WMD, 24.39%; 95% confidence interval, 12.33-36.45; P < 0.05). CONCLUSIONS: The present meta-analysis showed that the magnitude of canal expansion was higher with ODL than with FDL. There is a lack of compelling evidence to prove the superiority of one procedure over the other.
