A new simulation software, FracSim, significantly improved orthopaedic residents' understanding of fracture fixation biomechanics. This tool offers interactive visualization of 3D biomechanical concepts, enhancing surgical training.
Area of Science:
- Orthopaedic Surgery
- Biomechanical Engineering
- Medical Simulation
Background:
- Achieving optimal biomechanical stability in fracture fixation is critical for preventing complications.
- Understanding the complex 3D biomechanics of fracture fixation is challenging with traditional training methods.
Purpose of the Study:
- To develop and evaluate a novel simulation software, FracSim, for enhancing orthopaedic residents' understanding of fracture fixation biomechanics.
- To assess the impact of interactive 3D biomechanical visualization on surgical training.
Main Methods:
- FracSim software was developed using a library of finite element simulations.
- Orthopaedic residents underwent an instructor-led educational session using FracSim, focusing on bridge plating.
- Knowledge assessment included pretests, posttests, and questionnaires on biomechanical concepts and software usability.
Main Results:
- Resident test scores improved significantly from a mean of 5.6/10 to 8.0/10 after using FracSim (P < 0.001).
- Senior residents demonstrated higher baseline knowledge than junior residents (P = 0.04).
- Residents found FracSim realistic, purposeful, efficient, engaging, and beneficial for learning fracture fixation biomechanics.
Conclusions:
- FracSim provides an effective and engaging platform for interactive visualization of 3D fracture fixation biomechanics.
- The software shows potential for improving orthopaedic learners' comprehension of complex biomechanical principles.
- Further research is needed to assess long-term knowledge retention and compare with traditional educational approaches.
