Summary
This study introduces a novel, inexpensive simulator for minimally invasive spine surgery (MISS) training. The simulation effectively improved neurosurgery residents' confidence in performing MISS procedures, offering a viable new teaching method.
Area of Science:
- Neurosurgery
- Medical Education
- Surgical Simulation
Background:
- Minimally invasive spine surgery (MISS) is a rapidly growing field in neurosurgery.
- Neurosurgery residents require specialized training in MISS techniques.
- Work hour restrictions limit traditional hands-on training opportunities for residents.
Purpose of the Study:
- To develop and evaluate a novel simulation model for minimally invasive spine surgery (MISS) training.
- To assess the impact of the simulation model on neurosurgery residents' self-assessed competence.
- To provide an alternative educational strategy for acquiring MISS skills.
Main Methods:
- A simulator was constructed using a Plexiglas frame, halo frame, and interchangeable copper tubing to mimic a working portal.
- Deer spine specimens were used for laboratory exercises focused on drilling techniques.
- Eight neurosurgery residents completed pre- and post-simulation self-assessment surveys on their confidence levels.
Main Results:
- Residents showed a statistically significant improvement in self-assessed confidence for performing MISS laminectomy (mean increase of 1.25 points, P = 0.0015).
- Senior residents demonstrated an improved, though not statistically significant, confidence in MISS pedicle screw placement (mean increase of 1.00).
- Exit surveys indicated encouraging feedback on the simulation exercises.
Conclusions:
- The developed MISS simulator is a feasible, inexpensive, and reproducible tool for neurosurgery resident training.
- This simulation model offers a valuable new teaching method for spine surgery education.
- Further research is warranted, though large-scale trials may be limited by ethical considerations regarding patient safety.
