To verify whether the pedicle screw placement (PSP) skills of young surgeons receiving immersive virtual reality surgical simulator (IVRSS) training could be improved effectively and whether the IVRSS-PSP training mode could produce a real clinical value in clinical surgery.
Twenty-four young surgeons were equally randomized to a VR group and a NON-VR group. Participants in VR group received IVRSS-PSP training, and those in NON-VR group used the conventional model of observing a spinal model first and then watching a teaching video of spinal surgery for 40 minutes x five. The nailing outcome of the participants before and after training was evaluated by statistical analysis in both groups.
Post-training data analysis showed that the success rate and accuracy rate of screw placement in VR group and NON-VR group were 82.9% and 69.6% vs. 74.2% and 55.4%, respectively, showing statistically significant differences between the two groups by chi-square test (P < 0.05).
The present study demonstrated that IVRSS-PSP was helpful to improve the success rate of PSP for young surgeons, and may provide valuable reference for PSP training of young surgeons. In addition, our study also showed a promising potential of the VR technology in surgical simulation training.
验证接受沉浸式虚拟现实手术模拟器 (IVRSS) 培训的年轻外科医生的椎弓根螺钉放置 (PSP) 技能是否可以得到有效提高，以及 IVRSS-PSP 培训模式是否能在临床手术中产生真正的临床价值。
将 24 名年轻外科医生等分为 VR 组和 NON-VR 组。VR 组接受 IVRSS-PSP 培训，NON-VR 组先观察脊柱模型，然后观看 40 分钟 x 5 次脊柱手术教学视频。通过统计分析评估两组参与者培训前后的钉道结果。
培训后数据分析显示，VR 组和 NON-VR 组的螺钉放置成功率和准确率分别为 82.9%和 69.6%与 74.2%和 55.4%，卡方检验显示两组间差异有统计学意义 (P<0.05)。
本研究表明，IVRSS-PSP 有助于提高年轻外科医生 PSP 的成功率，可为年轻外科医生的 PSP 培训提供有价值的参考。此外，我们的研究还表明 VR 技术在手术模拟培训中具有广阔的应用前景。
