Summary
A new free online simulator for Transforaminal Lumbar Interbody Fusion (TLIF) surgery significantly improved resident performance compared to traditional methods. This accessible tool is especially beneficial for trainees with limited surgical experience, enhancing spinal surgery education.
Area of Science:
- Medical Education
- Surgical Simulation
- Spinal Surgery
Background:
- Transforaminal Lumbar Interbody Fusion (TLIF) is a complex surgical procedure demanding extensive resident training.
- Current training simulators are expensive and inaccessible, with a lack of free online alternatives.
- This study aimed to develop and validate the first free, online, computer-based interactive simulator for TLIF.
Purpose of the Study:
- To evaluate the effectiveness of a novel computer-based interactive simulator for teaching TLIF surgical steps.
- To compare the performance of residents trained with the simulator versus a traditional PDF-based technique.
- To assess resident satisfaction and identify specific benefits for trainees with varying experience levels.
Main Methods:
- A randomized controlled trial involving 42 orthopedic surgery residents.
- Two groups: one trained with the TLIF simulator, the other with a PDF technique.
- Performance assessed via TLIF checklist and Objective Structured Assessment of Technical Skills (OSATS) on a sawbone model.
Main Results:
- Residents using the simulator demonstrated significantly better performance on the TLIF checklist (p=0.01).
- The simulator showed a trend towards higher OSATS scores, though not statistically significant (p=0.17).
- The simulator was particularly effective for residents with less than 15 prior TLIF observations, showing greater relative improvement.
Conclusions:
- The free, online TLIF simulator is a valuable educational tool for teaching complex spinal surgery procedures.
- It offers significant benefits for residents with limited experience or those outside the spine subspecialty.
- The simulator's accessibility removes educational barriers, supporting independent, at-home surgical skills development.
