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.
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.
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).
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.
传统的基于讲座的学习（LBL）教学模式常常导致学生主动性和独立思考能力较差，学习兴趣低下。本研究旨在探讨CT三维重建和3D打印技术结合CBL教学模式在骨科临床教学及住院医师规范化培训中的应用。
随机选取我院60名住院医师，在骨外科课程中进行关节骨科内容的教学。入院时将他们随机分为三组，分别采用LBL教学模式、CBL教学模式、CT三维重建和3D打印技术结合CBL教学模式。
CBL+3D打印组规范化培训学生的理论知识成绩和临床技能成绩显著高于LBL组或CBL组。CBL+3D打印组学生在自我能力评价方面的认可度显著更高。CBL+3D打印组学生的总体教学满意度为85.00%（P<0.05）。
CT三维重建和3D打印技术与CBL教学模式相结合有助于学生在关节骨科住院医师规范化培训中掌握理论知识和实践技能，能有效提高教学质量。
