Novel Simulation With 3D-Printed Spine for Teaching Durotomy Repair: A Technique Guide and Validation Study
Summary
A new 3D-printed simulator effectively trains surgical trainees in durotomy repair, a critical skill for preventing cerebrospinal fluid leaks. This realistic model enhances surgical education and patient safety by allowing practice in a controlled environment.
Area of Science:
- Neurosurgery
- Surgical Education
- Biomedical Engineering
Background:
- Durotomies, or tears in the dura mater, can cause cerebrospinal fluid leakage and complications.
- Repairing durotomies is a crucial skill for orthopedic and neurosurgical trainees.
- Current training methods present challenges for developing proficiency safely.
Purpose of the Study:
- To develop and evaluate a novel 3-dimensional (3D) printed simulation model for teaching intraoperative durotomy repair.
- To provide surgical trainees with a safe and controlled environment for practicing durotomy repair techniques.
Main Methods:
- Development of a 3D-printed simulation model with lumbar and thoracic windows.
- Utilized 3D-printed and repurposed components for a lifelike intraoperative scenario.
- Assessed performance of junior residents, senior residents, fellows, and attending surgeons.
Main Results:
- The simulation model realistically replicated an in vivo intraoperative durotomy repair scenario.
- More experienced surgeons (senior residents, fellows, attendings) initially outperformed junior residents.
- All participant groups demonstrated improved performance with repeated simulator use.
Conclusions:
- The 3D-printed model provides a valid and effective tool for surgical trainees to practice durotomy repair.
- The simulator facilitates skill acquisition and improvement in a risk-free setting.
- This novel simulator has the potential to enhance surgical training and improve patient outcomes by reducing durotomy-related complications.
