Abstract

Background: Traditional orthopedic teaching methods have inherent limitations in conveying complex three-dimensional anatomical relationships essential for surgical planning and execution. Three-dimensional (3D) printing technology offers a potential solution to these educational challenges, but systematic evaluation of its specific educational impact in orthopedic residency training remains limited.

Purpose: This study aimed to evaluate the educational efficacy of in-house 3D-printed patient-specific anatomical models in orthopedic training through assessment of three core domains: anatomical comprehension, surgical planning proficiency, and clinical teaching utility.

Methods: In this analytical observational study, paper-based questionnaires were distributed to 145 orthopedic residents at Hubei University of Medicine who participated in clinical teaching sessions using 3D-printed anatomical models between January 2025 and March 2025. Participants rated their experiences on a 10-point Likert scale. Data were analyzed using descriptive statistics.

Results: The response rate was 81.4% (n=118). A majority (85.6%) of residents reported enhanced understanding of complex anatomical structures. First-year residents demonstrated higher satisfaction (mean score 7.9) compared to more advanced trainees (mean scores 7.3 and 6.9). Small group settings (4-6 participants) were preferred by 76.3% of respondents. Physical manipulation of models received the highest educational value rating (mean score 8.1). Primary limitations included production time (45.8%), material durability (38.6%), and limited model varieties (35.6%). Nearly half (43.2%) of residents requested more frequent practice sessions.

Conclusion: 3D-printed anatomical models significantly enhance orthopedic resident education, particularly for complex structures and junior trainees. Small-group, instructor-guided implementation maximizes educational benefits. When strategically integrated into existing curricula, in-house production enables widespread access across training levels with minimal resource constraints.

骨科学员对患者特异性3d打印解剖模型的教育效用的感知:一项基于问卷的观察研究。
背景:传统的骨科教学方法在传达复杂的三维解剖关系方面存在固有的局限性,这对手术计划和执行至关重要。三维(3D)打印技术为这些教育挑战提供了一个潜在的解决方案,但对其在骨科住院医师培训中的具体教育影响的系统评估仍然有限。目的:本研究旨在通过对解剖理解、手术计划熟练程度和临床教学效用三个核心领域的评估,评估内部3d打印患者特异性解剖模型在骨科培训中的教育效果。方法:在本分析性观察研究中,对2025年1月至2025年3月期间参加3d打印解剖模型临床教学的145名湖北医科大学骨科住院医师进行纸质问卷调查。参与者以10分的李克特量表对他们的经历进行评分。数据分析采用描述性统计。结果:有效率为81.4% (n=118)。大多数(85.6%)的住院医生报告对复杂解剖结构的理解增强了。第一年住院医生表现出更高的满意度(平均得分7.9),而更高级的实习生(平均得分7.3和6.9)。76.3%的受访者更喜欢小组设置(4-6人)。模型的物理操作获得最高的教育价值评价(平均得分8.1)。主要的限制包括生产时间(45.8%)、材料耐久性(38.6%)和有限的模型品种(35.6%)。近一半(43.2%)的住院医生要求更频繁地练习。结论:3d打印解剖模型可显著提高骨科住院医师教育水平,特别是对复杂结构和初级实习生。小团体、教师指导的实施使教育效益最大化。当策略性地整合到现有课程中时,内部生产可以在最小的资源限制下广泛访问培训级别。
