The mixed reality (MR) technique has recently been widely used in the orthopedic surgery with satisfactory results reported. However, few studies have focused on the application of MR in the Lumbar fracture (LF). In this retrospective study, our aim is to analyze some findings by investigating the feasibility of MR applied to lumbar fracture treatment. Posterior vertebrectomy has been operated on 7 patients. The MR-based intraoperative three-dimensional image-guided navigation system (MITINS) was used to assist implantation of pedicle screws. The feasibility and safety of pedicle screw implantation were assessed by postsurgery radiography. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were used to assess the pain level and recovery situation before and after surgery. 57 pedicle screws were safely and precisely placed into three-dimensional lumbar models by using MITINS. No screw was found outside the pedicle of the models, and it was not necessary for the X-ray to provide extra locative information during the operation with the use of MITINS. In summary, the application of MITINS is feasible, safe, and accurate while the lumbar fracture surgery is processing, providing satisfactory assistance for spine surgeons.
混合现实（MR）技术最近在骨科手术中得到了广泛应用，已有令人满意的结果报道。然而，很少有研究关注 MR 在腰椎骨折（LF）中的应用。在这项回顾性研究中，我们旨在通过研究 MR 在腰椎骨折治疗中的应用来分析一些发现。对 7 例患者进行了后路椎体切除术。使用基于 MR 的术中三维图像引导导航系统（MITINS）辅助椎弓根螺钉植入。术后影像学评估椎弓根螺钉植入的可行性和安全性。视觉模拟评分（VAS）和 Oswestry 功能障碍指数（ODI）用于评估手术前后的疼痛水平和恢复情况。使用 MITINS 将 57 枚椎弓根螺钉安全、精确地植入三维腰椎模型中。在使用 MITINS 时，模型的椎弓根内没有发现螺钉，手术过程中不需要 X 射线提供额外的定位信息。总之，在进行腰椎骨折手术时，MITINS 的应用是可行、安全和准确的，为脊柱外科医生提供了满意的帮助。
