Application of virtual reality technology in clinical teaching of cervical pedicle screw placement
Objective:To investigate the effectiveness of virtual reality(VR)technology in the clinical teaching of cervical pedicle screw placement.Methods:Twenty medical students interning in the Department of Orthopedics of Peking Union Medical College Hospital from September 2023 to February 2024 were enrolled.They were randomly divided into the traditional teaching group and the VR teaching group,with 10 students in each group.The traditional teaching group received conventional teaching,while the VR teaching group underwent simulation training for cervical pedicle screw placement using a VR teaching system.The teaching effectiveness was evaluated through surgical structure identification,learning outcomes,the accuracy of pedicle screw placement,the total time for pedicle screw placement,and the general surgical operation assessment form for residents.Results:The medical students in the VR teaching group scored significantly higher in surgical structure identification,course engagement,learning efficiency,skill acquisition,course evaluation,and educational assessment compared to the traditional teaching group(all P<0.05).Compared to the traditional teaching group,the accuracy of pedicle screw placement was significantly higher in the VR teaching group than in the traditional teaching group,and the total time for pedicle screw placement was significantly shorter in the VR teaching group(both P<0.05).Preoperative preparation,surgical maneuvers,instrument handling,operational fluency,basic knowledge,and overall performance scores were also significantly higher in the VR teaching group compared to the traditional teaching group(all P<0.05).Conclusions:Compared with traditional teaching methods,the VR teaching system helps medical students better understand cervical spine anatomy and master pedicle screw placement skills,making it worthy of promotion and application in clinical teaching.
