PurposeThe aim of this study is to investigate, using a meta-analysis, differences in safety and effectiveness between a titanium mesh bone graft and bone graft alone for the treatment of thoracolumbar spinal tuberculosis.MethodsPubMed, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang (Chinese) and other databases were searched up to April 2019 using predetermined terms. Published studies investigating the safety and effectiveness of a titanium mesh bone graft versus a bone graft alone for the treatment of thoracolumbar spinal tuberculosis were included. Two authors independently extracted the data and evaluated the quality of the included articles. A meta-analysis of relevant outcome indicators was performed using Stata 14 and RevMan 5.3 software.ResultsWe retrieved 8 retrospective studies that met the inclusion criteria and enrolled a total of 401 patients, including 203 patients in the titanium mesh group and 198 in the bone graft only group. Each study was rated as high quality. The meta-analysis results showed no statistically significant differences between the 2 bone graft methods in terms of surgery-related indicators, clinical effectiveness, imaging and complications.ConclusionsBoth titanium mesh and bone grafts alone are effective for the treatment of thoracolumbar spinal tuberculosis based on safety. However, the results of this study do not support the superiority of titanium mesh bone grafts reported in previous studies. Because of the high risk of bias of the conclusions of a meta-analysis of non-randomized studies and the small sample sizes for some of the most important outcomes, randomized controlled trials are expected to further examine the reliability of the present findings.
