Abstract

Objective: The diagnosis and treatment of arthropathic orthopaedic conditions are inherently linked to anatomical structures, necessitating strong spatial visualization abilities in students. Providing intuitively accessible methods for students to master specialized knowledge presents a formidable challenge for educators. This study aims to evaluate the pedagogical value of integrating 3D-printed model with mixed reality (MR) technology in clinical orthopaedic surgery education.

Methods: Thirty-six senior clinical medical undergraduates were randomized into two groups. The experimental group underwent training using the combined 3D- printed model and mixed reality (MR) technology, while the control group received traditional instruction. Learning outcomes were evaluated through standardized Objective Structured Clinical Examination (OSCE) assessments and questionnaires. Correlation analysis was conducted between total OSCE scores and questionnaire scores.

Results: The experimental group achieved significantly higher OSCE scores compared to the control group (p < 0.05). Questionnaire analysis indicated that a majority of students in the experimental group perceived the integrated 3D printing and mixed reality (MR) teaching approach as innovative. They also reported significant improvements in anatomical comprehension, interest stimulation, teacher-student interaction, knowledge retention, learning efficiency, and practical skills (p < 0.05). Furthermore, OSCE total scores demonstrated strong positive correlations with all questionnaire subdomains (r > 0.8, p < 0.001). The strongest correlation was observed between learning efficiency and OSCE total scores (r = 0.918).

Conclusion: Integrating 3D-printed model and MR technology into orthopedic joint surgery clinical teaching significantly boosts student performance, learning efficiency, and overall teaching quality, demonstrating strong potential for wider application.

结合混合现实与3D打印的虚拟物理混合教学模式在临床关节骨科教学中的应用
目的:关节病骨科疾病的诊断和治疗与解剖结构有着内在的联系,要求学生具有较强的空间可视化能力。为学生提供直观易懂的方法来掌握专业知识,是教育工作者面临的巨大挑战。本研究旨在评估3d打印模型与混合现实(MR)技术在临床骨科外科教学中的应用价值。方法:36名临床医学本科高年级学生随机分为两组。实验组采用3D打印模型与混合现实(MR)技术相结合的方法进行训练,对照组采用传统方法进行训练。通过标准化的客观结构化临床检查(OSCE)评估和问卷调查来评估学习效果。欧安组织总得分与问卷得分进行相关分析。结果:实验组OSCE评分显著高于对照组(p < 0.05, p < 0.918)。结论:将3d打印模型与MR技术整合到骨科关节外科临床教学中,可以显著提高学生的学习成绩、学习效率和整体教学质量,具有广阔的应用前景。

期刊介绍: Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles. Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery. Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact. The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
