Abstract

Abstract:

BACKGROUND:The newly developed pelvic deformity measurement software can increase the accuracy rate of pelvic displacement. It also breaks through the learning difficulties of pelvic reduction frame under the practice of CBL teaching mode and three-dimensional (3D) printing technology.

OBJECTIVE: To explore the application of pelvic deformity measurement software combined with 3D printing technology in the teaching of pelvic reduction frame under CBL teaching mode.

METHODS: A total of 96 advanced training physicians and postgraduates at the First Ward of Orthopedics, Chinese PLA General Hospital, China from 2015 to 2016 were divided into traditional teaching group (n=53) and new teaching model group (n=43) according to the duration of study in the hospital. The new teaching model group underwent preoperative planning using pelvic deformity measurement software and guided by CBL teaching mode. The actual operation was simulated and testing was conducted on the 3D-printed model. The teaching results in the two groups were assessed.

RESULTS AND CONCLUSION: (1) The new teaching model group was significantly superior to the traditional teaching group in the teaching attraction, the understanding of typical pelvic fractures, the ability to make surgical plans for pelvic closed reduction, the number of operation exercises required for external operations, overall satisfaction, and practical training assessment (P < 0.05). (2) To conclude, under the guidance of CBL teaching mode, using pelvic deformity measurement software to help determine preoperative planning, the new teaching mode that simulated actual operation on a 3D printing model is applied in clinical teaching of pelvic reduction frame, which can strengthen students’ enthusiasm for learning and improve the understanding of pelvic fracture and the ability to plan for surgery, and allow students to quickly master the use of pelvic reduction frame.
