The Application of CT 3D Reconstruction and 3D Printing Technology Combined with CBL Teaching Mode in the Clinical Teaching of Joint Orthopedics.

Purpose: The traditional teaching mode Lecture Based Learning (LBL) often results in student's poor initiative and independent thinking ability and low learning interest. This study aims to investigate the application of CT 3D reconstruction and 3D printing technology combined with CBL teaching mode in the clinical teaching of orthopedics and standardized training of residents.

Methods: Sixty residents of our hospital were randomly selected to conduct the teaching of joint orthopedic content in orthopedic surgery courses. They were randomly divided into three groups at the time of admission, which adopted LBL teaching mode, CBL teaching mode, CT 3D reconstruction and 3D printing technology combined with CBL teaching mode, respectively.

Results: The theoretical knowledge scores and clinical skills scores of the standardized training students in the CBL+3D printing group were significantly higher than those in the LBL or CBL group. Students in CBL+3D printing group had significantly higher recognition in self-ability evaluation. The overall teaching satisfaction of students in CBL+3D printing group was 85.00% (P < 0.05).

Conclusion: The combination of CT 3D reconstruction and 3D printing technology with CBL teaching mode can help the students to master the theoretical knowledge and practical skills in the standardized training of joint orthopedics residents, which can effectively improve the teaching quality.
