Abstract

For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on-going. We hypothesize that three-dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi-colored and multi-material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ∼1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi-colored, multi-material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.

摘要

几个世纪以来,尸体一直是解剖学教育的基石。由于课程重点、成本、可用性、专业知识和伦理问题的变化,一些医学院已经用塑化切片、塑料模型、成像和数字模型取代了湿尸体标本。关于这些替代教学资源的优缺点的讨论仍在继续。我们假设三维打印(3DP)模型可以替代或实际上增强解剖学教育的现有资源。根据塑化上肢切片,开发了一种新型的多色多材料上肢 3DP 模型,其空间分辨率约为 1 毫米,可捕获肌肉、神经、动脉和骨骼。本研究旨在从学习者的角度探讨 3DP 模型的教育价值。学生(n=15)将开发的 3DP 模型与塑化切片进行了比较,并通过问卷调查和焦点小组讨论,提供了他们对使用 3DP 模型学习体验的看法。所有学生都认为 3DP 模型中的解剖特征准确。学生强调了 3DP 模型的几个积极方面,例如按组织类型进行颜色编码、灵活性以及在处理和检查标本时需要的护理较少,这有助于理解解剖结构之间的关系。然而,学生们报告说,3DP 模型中的解剖特征与塑化标本相比不那么真实。多色、多材料的 3DP 模型是解剖学教育的宝贵资源,也是湿尸体或塑化切片的极好补充。《解剖科学教育》11: 54-64. © 2017 美国解剖学家协会。
