Interobserver Agreement When Using or 3D Models (Fleiss Kappa, κ)

	CT	3D
Juniors	0.172	0.259
Seniors	0.216	0.351

Subjective survey results demonstrated that 87.5% of the residents agreed or strongly agreed with the accuracy and appearance of the 3D model’s representation of acetabular fractures, and 84% desired to further incorporate 3D models into other areas of their education. Residents also agreed with the fact that the CT or 3D model was sufficient for identifying acetabular fractures. Prior to using the 3D model, residents disagreed about feeling confident identifying these fractures. They agreed that the 3D model improved their confidence with fracture identification (Fig. 3).
