Abstract：
BACKGROUND: Augmented reality navigation is the one of the navigation technologies that allows computer-generated virtual images to be projected onto a real-world environment. Augmented reality navigation can be used in spinal tumor surgery. However, it is unknown if there are any pitfalls when using this technique.
METHODS: The patient in this report underwent complete resection of a cauda equina tumor at the L2-L3 level using microscope-based augmented reality navigation. Although the registration error of navigation was <1 mm, we found a discrepancy between the augmented reality navigation images and the actual location of the tumor, which we have called \"navigation mismatch\". This mismatch, which was caused by the mobility of the spinal tumor in the dura mater, seems to be one of the pitfalls of augmented reality navigation for spinal tumors.
CONCLUSIONS: Combined use of intraoperative ultrasound and augmented reality navigation seems advisable in such cases. J. Med. Invest. 71 : 174-176, February, 2024.

摘要：
背景技术增强现实导航是允许将计算机生成的虚拟图像投影到现实世界环境上的导航技术之一。增强现实导航可用于脊柱肿瘤手术。然而,使用这种技术时是否有任何陷阱是未知的。
方法：本报告中的患者使用基于显微镜的增强现实导航在L2-L3水平接受了马尾肿瘤的完全切除。虽然导航的配准误差<1mm,我们发现增强现实导航图像和肿瘤的实际位置之间存在差异，我们称之为“导航不匹配”。这种不匹配，这是由硬脑膜中脊柱肿瘤的活动性引起的，似乎是脊柱肿瘤增强现实导航的陷阱之一。
结论：在这种情况下，联合使用术中超声和增强现实导航似乎是可取的。J.Med.投资。71:174-176，二月，2024.
