Three-Dimension Sawbone Models and Shadow-Play: A Low-Cost Approach to Improve Orthopedic Plain Radiograph Reading in Medical Students
Background
The usage of 3D sawbone models and shadow-play is a novel teaching method in orthopedic education. The aim of this study was to evaluate the effectiveness of 3D sawbone models and shadow-play in improving medical student orthopedic knowledge and interpretation of plain radiographs.
Methods
Ninety-three medical students with no prior clinical orthopaedic experience were recruited into 2 groups: Group 1 underwent conventional education methods and Group 2 underwent a sawbone and shadow-play education. A pre and post-test designed to determine orthopedic knowledge and interpretation of plain radiographs was performed. Five participants were randomly selected for a semi-structured qualitative interview postintervention.
Results
There was an increase in mean test scores in both groups. The difference in the means of pre- and post-test average outcomes between the control group was 3.00 (SD = 2.08), as compared to 4.74 (SD = 2.69) for the sawbone group. Group 2 (sawbone) exhibited a significantly better improvement. (p < 0.001). Interviews revealed several themes: improved engagement, enhanced visualization, holistic learning, and challenges.
Conclusions
The utilization of 3D sawbone models and shadow-play as teaching tools in orthopedics demonstrates significant efficacy and is more effective than conventional teaching methods in novice medical students. Students perceived the incorporation of sawbone models and shadow-play as highly engaging, providing them with enhanced visualization capabilities, consequently fostering a deeper comprehension of anatomical structures and X-ray interpretations.
期刊介绍：
The Journal of Surgical Education (JSE) is dedicated to advancing the field of surgical education through original research. The journal publishes research articles in all surgical disciplines on topics relative to the education of surgical students, residents, and fellows, as well as practicing surgeons. Our readers look to JSE for timely, innovative research findings from the international surgical education community. As the official journal of the Association of Program Directors in Surgery (APDS), JSE publishes the proceedings of the annual APDS meeting held during Surgery Education Week.
