Abstract
PURPOSE: To assess the efficacy of immersive virtual reality surgical simulator (IVRSS) training on pedicle screw placement (PSP) in surgical graduate students.
METHODS: Sixteen inexperienced surgical graduate students were equally randomized to an experimental group (VR group) and a control group (NON-VR group). Students in VR group performed PSP on IVRSS and those in NON-VR group were given a traditional introductory teaching session before a cadaver test. A total of 8 adult fresh cadavers including 6 males and 2 females were collected and randomly allocated to the two groups. Each group performed bilateral T11-L4 PSP on the cadavers independently and the outcomes of PSP in terms of the accuracy, success rate and the efficiency were assessed by CT and compared between the two groups statistically.
RESULTS: The accuracy rate of PSP in VR group was 89.6% vs. 60.4% in NON-VR group (P<0.05); the success rate was 100% vs. 79.2% (P<0.05); and the mean time was 2.8±1 min vs. 4.9±1 min (P<0.05), all showing significant differences between the two groups.
CONCLUSION: The IVRSS-PSP training model is superior to the traditional training model in term of the accuracy, success rate and efficiency, showing a potential prospective in training new orthopedic spine surgeons.
