Objectives: There is an increasing number of complex and varied surgical techniques and implants in orthopedic trauma. As the paradigm shift in orthopedic surgical education is turning to competency-based curricula and technology is becoming more affordable, new immersive virtual reality (IVR) simulation systems are emerging. The main objective of this study was to evaluate the utility of IVR simulation for learning a complex surgical technique; the application of a Trochanteric Femoral Nail Advanced (TFNA™). Methods: Ten residents participated in the evaluation of the application of TFNA™ in a Synbone® model during an advanced fractures treatment course. Five of them had a previous practice session using a VR simulator to learn the technique. All of them applied a TFNA™ during the course and were then asked to repeat it. Time to completion and the number of steps completed by each group were compared between both groups. Results: The VR group took 25.84 min to complete (standard deviation [SD] 6.14) and the control group 31.6 min to complete (SD 19.3). There was no statistically significant difference between both groups, but there was a tendency for the VR group to complete more steps and finish earlier than the control group (P = 0.554). Conclusion: IVR simulation could be a more accessible way to provide a safe environment where participants can learn a new surgical technique. It is important to develop proficiency-based progressive training programs with specific educational goals that incorporate simulation and emerging technology as a tool. Larger, randomized, internal and external validation studies are needed.
