A Randomized Trial of Preoperative Practice in a Simulated Operative Environment: 3D Printed Pilon Model Improves...

Area of Science:

• Orthopaedic Surgery
• Medical Simulation
• Surgical Education

Background:

• Preoperative planning is crucial for complex fractures.
• Traditional planning methods may have limitations in visualizing complex anatomy.
• 3D printing offers a novel approach to surgical simulation.

Purpose of the Study:

• To assess the impact of 3D-printed fracture models on surgical residents' performance.
• To compare operative outcomes between residents using 3D models and those using standard planning.
• To evaluate the efficacy of 3D printing in surgical training.

Main Methods:

• A complex pilon fracture was replicated using 3D printing.
• Orthopaedic surgery residents were randomized into two groups: routine planning and 3D model practice.
• Operative performance was assessed via video motion capture and blinded reviewer evaluation.

Main Results:

• The 3D-printed model group showed significantly less hand distance traveled during fixation (p=0.04).
• Residents using 3D models achieved more acceptable fracture reductions (p=0.009) and higher global rating scores (p=0.0095).
• Three residents in the 3D group completed the procedure within the 45-minute time limit.

Conclusions:

• Preoperative planning with 3D-printed models enhances surgical resident performance.
• 3D printing provides a valuable tool for improving surgical skills and patient outcomes in complex fracture management.
• This technology holds promise for advancing orthopaedic surgical education.
