Summary
Beginner surgeons improved pedicle screw fixation (PSF) accuracy and reduced procedure time using 3D-printed spine models for repeated training. This innovative approach enhances surgical skills before actual patient procedures.
Area of Science:
- Orthopedic surgery
- Medical education technology
- 3D printing applications
Background:
- Surgical training for pedicle screw fixation (PSF) is constrained by patient safety and efficiency concerns.
- Personalized 3D printing technology offers novel solutions for medical training.
Purpose of the Study:
- To assess the educational impact of 3D-printed spine models for novice surgeons learning PSF.
- To determine if 3D models improve screw accuracy and reduce procedure duration.
Main Methods:
- Life-size lumbar spine (L1-3) replicas were created from CT scan data using 3D printing.
- Four residents performed PSF three times each, totaling 18 screw fixations per resident.
- Procedure time and pedicle violation rates were recorded for each trial.
Main Results:
- Average procedure time decreased progressively across trials (42.1 to 32.1 minutes).
- Average pedicle screw accuracy scores improved with each trial (13.0 to 16.0).
- Repeated practice on 3D models led to reduced time and increased accuracy.
Conclusions:
- Repeated training with 3D-printed spine models effectively decreases procedure time and enhances PSF accuracy.
- Patient-specific 3D models enable pre-surgical simulation, improving resident surgical skills.
- This technology presents a valuable tool for surgical education in PSF techniques.
