Abstract:
Objective To explore the feasibility and effect of 3D modeling and printing technology in constructing bone fracture models and assisting clinical teaching at the department of traumatic orthope-dics. Methods CT scan images of bone fractures were reconstructed by Mimics software. The digital 3D bone fracture models were constructed and the interactive multimedia teaching videos were output. More-over, all bone fracture models were printed by using fusion deposition modeling (FDM). At the end of the teaching course, a questionnaire survey was conducted to evaluate the teaching effect. Results The digital models of common bone fractures at the department of traumatic orthopedics were established, and the in-teractive multimedia teaching videos were output. A traumatic orthopedic teaching model with a 1∶1 scale was printed out. The questionnaire survey indicated that the application of 3D modeling and printing tech-nology to build bone fracture model with PPT teaching can obviously improve students' understanding and mastery of relevant theoretical knowledge. They helped students better remember the type of bone fractures and how to choose the correct internal fixation methods. The teaching effect was satisfactory. Conclusions 3D modeling and printing technology was applied to build bone fracture models to assist clinical teaching at the department of traumatic orthopedics. It was found that the printed 3D bone fracture models can stimulate students' enthusiasm for learning and improve their learning effect. This method has good application value.
