Medical and surgical education is an expansive field fraught with many challenges. Technology such as virtual reality could be a new venue that can offer a solution to improve surgical training.
The objective of this prospective, blinded study was to evaluate virtual reality as a training model for orthopedic surgery and surgical training at large.
Fourth-year medical students with novice skills volunteered to participate in this observer-blinded 1:1 randomized controlled trial. They had no prior experience in tibia intramedullary nail (IMN) surgery. They were randomized into traditional technique guide education and virtual reality. The participants were timed on their mock surgery, and a blinded observer was utilized to subjectively grade their performance throughout the procedure using the Global Assessment 5-point Rating Scale and Procedure-Specific Checklist.
Thirty-eight participants were recruited and randomized into virtual reality (19) and traditional (19) groups. There were trends in all categories favoring the virtual reality group. The VR group had improved time to completion (9.6 minutes vs 12.2 minutes, P = 0.034) and reduced need for corrections within the mock procedure (2.2 vs 2.5; P = 0.05).
Virtual reality training was more effective than traditional training in learning and completing the steps of the tibia IMN surgery for novice medical students. Virtual reality training may be a useful method to augment orthopedic education and surgical training.
医学和外科教育是一个充满诸多挑战的广阔领域。虚拟现实等技术可能是一个新途径，能够为改善外科培训提供解决方案。
这项前瞻性、双盲研究的目的是评估虚拟现实作为骨科手术及整体外科培训的一种培训模式。
技能 novice 的四年级医学生自愿参与这项双盲 1:1 随机对照试验。他们此前没有胫骨髓内钉（IMN）手术经验。他们被随机分为传统技术指导教育组和虚拟现实组。对参与者的模拟手术进行计时，并由一名双盲观察者使用全球评估 5 分制评分量表和特定程序检查表在整个手术过程中对他们的表现进行主观评分。
招募了 38 名参与者并将其随机分为虚拟现实组（19 人）和传统组（19 人）。所有类别都有倾向于虚拟现实组的趋势。虚拟现实组完成时间有所改善（9.6 分钟对 12.2 分钟，P = 0.034），且模拟手术过程中需要纠正的次数减少（2.2 次对 2.5 次；P = 0.05）。
对于 novice 医学生而言，在学习和完成胫骨 IMN 手术步骤方面，虚拟现实培训比传统培训更有效。虚拟现实培训可能是增强骨科教育和外科培训的一种有用方法。
