Summary
This study found that while a 3D pedicle screw insertion simulator was well-received by surgical trainees and staff, a brief training session did not improve screw placement accuracy in cadaveric models.
Area of Science:
- Spine Surgery Education
- Surgical Simulation Technology
Background:
- Traditional pedicle screw insertion training relies on didactic methods and limited hands-on practice.
- Three-dimensional (3D) computer simulation offers potential for practicing complex surgical procedures.
Purpose of the Study:
- Evaluate the efficacy of a 3D software simulation tool for teaching pedicle screw insertion.
- Gather feedback on the simulator's utility in surgical education.
- Identify the role of simulation in surgical training.
Main Methods:
- A randomized control study involved surgical residents in a spine surgery course.
- One group received standard training; the other received an additional 1-hour 3D simulation session using CT-based models.
- Feedback was collected from trainees, fellows, and staff; screw placement was evaluated via CT.
Main Results:
- Eighty-two percent of trainees and all staff found the simulator beneficial.
- A total of 185 thoracic and lumbar pedicle screws were inserted.
- The 1-hour simulation did not improve physical screw placement accuracy.
Conclusions:
- A 3D computer-based simulator for pedicle screw insertion was integrated into a cadaveric course.
- The tool received positive regard from trainees and surgical staff.
- Limited simulation training did not enhance comfort or improve physical screw placement.
