To assess efficacy of immersive virtual reality (VR) surgical simulator training for pedicle screw placement (PSP) in surgical graduate students.
Sixteen inexperienced surgical graduate students were equally randomly assigned to an experimental group (VR group) and a control group (non-VR group). Students in the VR group performed PSP on the immersive VR surgical simulator, and students in the non-VR group were given a traditional introductory teaching session before a cadaver test. Eight adult fresh cadavers, 6 male and 2 female, were collected and randomly allocated to the 2 groups. Each group performed bilateral T11-L4 PSP on the cadavers independently, and the outcomes of PSP in terms of accuracy, success rate, and efficiency were assessed by computed tomography and compared between the 2 groups statistically.
Accuracy rate of PSP in the VR group was 89.6% versus 60.4% in the non-VR group (P < 0.05), success rate was 100% versus 79.2% (P < 0.05), and mean time was 2.8 ± 1 minutes versus 4.9 ± 1 minutes (P < 0.05), all showing significant differences between the 2 groups.
The immersive VR surgical simulator for PSP training model is superior to the traditional training model in terms of accuracy, success rate, and efficiency, showing potential in training new orthopedic spine surgeons.
评估沉浸式虚拟现实（VR）手术模拟器训练对外科研究生椎弓根螺钉置入（PSP）的效果。
16名缺乏经验的外科研究生被随机平均分为实验组（VR组）和对照组（非VR组）。VR组学生在沉浸式VR手术模拟器上进行PSP操作，非VR组学生在尸体测试前接受传统的入门教学课程。收集8具成年新鲜尸体，6男2女，随机分配到2组。每组独立在尸体上进行双侧T11-L4椎弓根螺钉置入，通过计算机断层扫描评估PSP的准确性、成功率和效率，并在两组间进行统计学比较。
VR组PSP准确率为89.6%，非VR组为60.4%（P<0.05）；成功率为100%，非VR组为79.2%（P<0.05）；平均时间为2.8±1分钟，非VR组为4.9±1分钟（P<0.05），两组间均有显著差异。
用于PSP训练的沉浸式VR手术模拟器模型在准确性、成功率和效率方面优于传统训练模型，在培训新的骨科脊柱外科医生方面显示出潜力。
