Position and complications of pedicle screw insertion with or without image-navigation techniques in the thoracolumbar spine: a meta-analysis of comparative studies

摘要: Computer-navigated pedicle screw insertion is applied to the thoracic and lumbar spine attain high accuracy a low rate of screw-related complications. However, some in vivo vitro studies have shown that no advantages are gained with use navigation techniques compared conventional techniques. Additionally, inconsistent conclusions been drawn various due different population characteristics methods used assess placement. Moreover, it not clear whether decreases incidence Therefore, this study was sought perform meta-analysis all available prospective evidence regarding or without human spine. We considered comparative assessed results placement PubMed, Ovid MEDLINE EMBASE databases were searched. Three published randomized controlled trials (RCTs) nine retrospective met inclusion criteria. These included total 732 patients whom 4,953 screws inserted. In conclusion, position grade I, II, III IV complication related significantly increased when comparison Future research area should include RCTs well-planned methodology limit bias report on validated, patient-based outcome measures.
