The SpineST-01 system effectively trains image-guided vertebrae cannulation, showing significant performance differences between novice and expert surgeons using objective metrics. This system offers a radiation-free method for skill development and performance evaluation.
Area of Science:
- Medical Simulation
- Surgical Training
- Spine Surgery
Background:
- The SpineST-01 is an image-guided system designed for practicing vertebrae cannulation.
- It provides real-time performance metrics and visual feedback during simulated surgical tasks.
Purpose of the Study:
- To evaluate the feasibility of the SpineST-01 system.
- To assess performance differences in image-guided cannulation among surgical trainees of varying experience levels.
Main Methods:
- A 3D printed spine model was used within a training box equipped with cameras.
- Passive markers on the instrument were tracked to calculate 8 performance metrics.
- Kruskal-Wallis and Mann-Whitney U analyses were performed on data from 25 participants (novices, intermediates, experts).
Main Results:
- Significant differences (P ≤ 0.05) were found in 6 of 8 metrics between expert and novice groups.
- Metrics showing significant differences included angle errors, speed, progress, time, and number of shots.
- Experts demonstrated superior performance compared to novices and intermediate groups.
Conclusions:
- The SpineST-01 system is a feasible tool for practicing image-guided cannulation on lumbar vertebrae.
- Objective performance metrics differentiate skill levels, supporting its use for developing navigation skills.
- The system allows for objective performance evaluation without radiation exposure.
