Medical education related to bone fracture must address numerous challenges including complex anatomical characteristics, diverse injury mechanisms, fracture typing, and treatment modalities. Our newly developed 3D printed model comprises components that may be combined or split to simulate various anatomical features, fracture types, and treatment modalities. This study aims to analyze the teaching utility of the new 3D-printed model compared with the traditional solid model.
This prospective study included 112 students randomly assigned to fracture-related education with a conventional model or the newly developed 3D-printed model. All students received 40 min of lecture, 20 min for femoral neck and 20 min for tibiofibular fractures, and a post-class quiz (10 min each) immediately followed. Scores on tests of fracture-related knowledge and user satisfaction were measured pre and post education for comparison.
The 3D printing group had an advantage in retention of anatomic knowledge, fracture typing and choice of treatment for the femoral neck fracture (P < 0.05). For the tibiofibular fracture the 3D printing group had an advantage in retention of anatomic knowledge and fracture complications (P < 0.05).Scores on the questionnaire survey also showed increased satisfaction in the 3D-printed model group(P < 0.05).
The proposed 3D-printed model can enhance the teaching effect significantly and has potential for widespread use in medical student education.
医学教育中涉及到骨折，必须解决许多挑战，包括复杂的解剖学特点、多样化的损伤机制、骨折分型和治疗方式。我们新开发的 3D 打印模型包含可组合或拆分的组件，以模拟各种解剖学特征、骨折类型和治疗方式。本研究旨在分析新的 3D 打印模型与传统实体模型相比的教学效用。
本前瞻性研究纳入 112 名学生，随机分配接受传统模型或新开发的 3D 打印模型相关骨折教育。所有学生接受 40 分钟的讲座，20 分钟用于股骨颈骨折，20 分钟用于胫腓骨骨折，随后立即进行课后测验（每个测验 10 分钟）。比较教育前后骨折相关知识和用户满意度测试的分数。
3D 打印组在保留解剖学知识、骨折分型和股骨颈骨折治疗选择方面具有优势（P<0.05）。对于胫腓骨骨折，3D 打印组在保留解剖学知识和骨折并发症方面具有优势（P<0.05）。问卷调查评分也显示 3D 打印模型组的满意度提高（P<0.05）。
所提出的 3D 打印模型可以显著提高教学效果，具有在医学生教育中广泛应用的潜力。
