Impact of 3D Printed Calcaneal Models on Fracture Understanding and Confidence in Orthopedic Surgery Residents.

This study found that 3Dp models increase the perceived accuracy of fracture assessment, though no statistically significant improvement in diagnostic accuracy was observed. The 3Dp models did improve trainee confidence, although this effect diminished with increasing residency year. In orthopedic residency training programs, 3Dp models of complex fractures can be a valuable educational tool, especially for junior trainees.
