Desktop-based computer-assisted orthopedic training system for spinal surgery.

Area of Science:

• Spinal Surgery Simulation
• Orthopedic Surgical Training
• Medical Education Technology

Background:

• Orthopedic simulation and training have advanced, with increasing trainee exposure to computer-based and laboratory methods.
• Despite advancements, there is a recognized need for enhanced simulation specifically for orthopedic spinal surgery training.

Purpose of the Study:

• To develop a computer-navigated simulation system for pedicle screw fixation.
• To validate the effectiveness of this training system in improving the skills of junior orthopedic trainees.

Main Methods:

• A fully simulated computer-navigated training system was developed for lumbar pedicle screw insertion.
• Real patient CT scans were utilized to generate real-time fluoroscopic images.
• Twelve senior house officers performed pedicle screw insertions pre- and post-training, assessed on time, accuracy, and radiation exposure.

Main Results:

• Training on the simulator system led to statistically significant improvements in the time taken to perform pedicle screw insertion (p < 0.05).
• Accuracy of pedicle screw fixation showed significant improvement post-simulation (p < 0.05).
• The number of radiation exposures required decreased significantly after simulator training (p < 0.05).

Conclusions:

• The fully simulated computer-navigated training system is an effective tool for junior orthopedic trainees learning pedicle screw fixation.
• This system can supplement operating room training, allowing skill acquisition in a controlled environment.
• The technology holds potential for training various orthopedic procedures, facilitating skill progression and improving operative performance.
