Summary
This study shows a virtual reality shoulder arthroscopy simulator effectively differentiates surgical skills. Experienced surgeons performed faster and more consistently, highlighting the simulator
Area of Science:
- Orthopaedic Surgery
- Medical Simulation
- Surgical Skills Assessment
Background:
- Developing and assessing surgical skills is crucial for patient safety and effective training.
- Traditional surgical training methods can be time-consuming and carry inherent risks.
- Virtual reality (VR) simulation offers a potential solution for objective skills evaluation.
Purpose of the Study:
- To evaluate the efficacy of a VR shoulder arthroscopy simulator in discriminating surgical skills across different expertise levels.
- To assess the simulator's ability to measure accuracy and efficiency in arthroscopic tasks.
Main Methods:
- A VR shoulder arthroscopy simulator with force feedback was used.
- Three groups participated: medical students (n=35), orthopaedic residents (n=22), and experienced faculty (n=21).
- Participants completed a standardized test involving touching virtual spheres, with data on time, path ratio, collisions, and injuries collected.
Main Results:
- Significant differences in test time and path ratio were observed based on surgical experience.
- Experienced surgeons demonstrated shorter and more consistent completion times.
- The simulator showed no significant difference in probe collisions, with low arthroscope collisions and injuries across all groups.
Conclusions:
- The VR shoulder arthroscopy simulator effectively discriminates between varying levels of surgical expertise.
- Computer-based simulation provides a valuable, risk-free platform for surgical skills development and assessment.
- This technology can enhance training efficiency and reduce operating room morbidity.
