To evaluate the efficacy of a self-developed mobile augmented reality navigation system (MARNS) in guiding spinal level positioning during intraspinal tumor surgery based on a dual-error theory.
This retrospective study enrolled patients diagnosed with intraspinal tumors admitted to Fujian Provincial Hospital between May and November 2023. The participants were divided into conventional x-rays and self-developed MARNS groups according to the localization methods they received. Position time, length of intraoperative incision variation, and location accuracy were systematically compared.
A total of 41 patients (19 males) with intraspinal tumors were included, and MARNS was applied to 21 patients. MARNS achieved successful lesion localization in all patients with an error of 0.38±0.12 cm. Compared to x-rays, MARNS significantly reduced positioning time (129.00±13.03 seconds vs. 365.00±60.43 seconds, p<0.001) and length of intraoperative incision variation (0.14 cm vs. 0.67 cm, p=0.009).
The self-developed MARNS, based on augmented reality technology for lesion visualization and perpendicular projection, offers a radiation-free complement to conventional x-rays.
基于双误差理论，评估自行研发的移动增强现实导航系统（MARNS）在脊髓肿瘤手术中引导脊髓节段定位的疗效。
本回顾性研究纳入了2023年5月至11月间在福建省立医院确诊为脊髓肿瘤的患者。根据所接受的定位方法，将参与者分为传统X线组和自行研发的MARNS组。系统比较定位时间、术中切口长度变化和定位准确性。
共纳入41例脊髓肿瘤患者（男性19例），其中21例应用了MARNS。MARNS在所有患者中均成功实现病变定位，误差为0.38±0.12 cm。与X线相比，MARNS显著缩短了定位时间（129.00±13.03秒 vs. 365.00±60.43秒，p<0.001）和术中切口长度变化（0.14 cm vs. 0.67 cm，p=0.009）。
自行研发的MARNS基于增强现实技术实现病变可视化和垂直投影，为传统X线提供了无辐射的补充。
