Suboptimal placements of pedicle screws may lead to neurological and vascular complications. Computer-assisted image guidance has been shown to improve accuracy in spinal instrumentation. Checking the accuracy of the navigation system during pedicle screw placement is fundamental. We describe a novel technique of using continuous accuracy check of the navigation system during O-arm-based neuronavigation to instrument the thoracolumbar region. Forty thoracic and 42 lumbar screws were inserted in 12 patients. The Mirza evaluation system was used to evaluate the accuracy of the inserted screws. There was no neurological injury and no need to reposition any screw. The accuracy of the screws placement was excellent. Our technique of continuous at will operational accuracy check of the neuronavigation system is associated with extreme accuracy of screw placement, no need to bring a patient back to the operating room to reposition a pedicle screw, and with excellent outcome.
椎弓根螺钉位置不当可能导致神经和血管并发症。计算机辅助图像引导已被证明可提高脊柱器械的准确性。检查椎弓根螺钉置入过程中导航系统的准确性至关重要。我们描述了一种新的技术，即在基于 O 臂的神经导航中使用导航系统的连续精度检查来进行胸腰椎区域的器械操作。在 12 名患者中插入了 40 个胸椎和 42 个腰椎螺钉。使用 Mirza 评估系统评估插入螺钉的准确性。没有神经损伤，也不需要重新定位任何螺钉。螺钉放置的准确性非常好。我们的神经导航系统连续随意操作精度检查技术与螺钉放置的极高准确性相关，无需将患者带回手术室重新定位椎弓根螺钉，并且具有极佳的效果。
