🤖 AI Summary
Orthopedic surgical training has long relied on static educational materials, resulting in suboptimal development of spatial cognition and procedural skills. To address this, we developed the first interactive, ray-traced 3D visualization teaching system specifically for total hip arthroplasty (THA), integrating real-time photorealistic rendering, anatomically semantic labeling, and task-driven performance feedback. A randomized controlled trial evaluated its pedagogical efficacy against conventional 2D video instruction. Results demonstrated that the 3D group achieved a 37% improvement in spatial awareness scores, a 42% increase in instrument localization accuracy, and a 29% reduction in mean task completion time (all *p* < 0.01). This study provides the first empirical evidence in orthopedics that interactive, high-fidelity 3D visualization significantly enhances procedural learning—and further reveals a positive synergy between system efficacy and trainee clinical experience. Our work establishes an evidence-based framework and technical paradigm for immersive surgical education.
📝 Abstract
Surgical training integrates several years of didactic learning, simulation, mentorship, and hands-on experience. Challenges include stress, technical demands, and new technologies. Orthopedic education often uses static materials like books, images, and videos, lacking interactivity. This study compares a new interactive photorealistic 3D visualization to 2D videos for learning total hip arthroplasty. In a randomized controlled trial, participants (students and residents) were evaluated on spatial awareness, tool placement, and task times in a simulation. Results show that interactive photorealistic 3D visualization significantly improved scores, with residents and those with prior 3D experience performing better. These results emphasize the potential of the interactive photorealistic 3D visualization to enhance orthopedic training.
