Abstract

Background: The emergence of 3D printing has revolutionized medical training and preoperative planning. However, existing models have limitations, prompting the development of newly designed flexible 3D-printed bone fracture models.

Methods: The designed flexible 3D-printed bone fracture models were evaluated by 133 trauma surgeons with different levels of experience for perceived value as educational tool or as preoperative planning tool.

Results: The models allowed drilling and showed resistance to manipulation and sterilization. Surgeons found the flexible model helpful for teaching and planning the reduction of fractures, planning and simulating osteosynthesis, understanding fractures, visualizing fractures, and planning surgical approaches.

Conclusions: Flexible 3D-printed bone fracture models offer a dynamic and realistic approach to understanding complex fractures, potentially improving surgical training and preoperative planning.

评估用柔性棒连接骨折碎片的3d打印骨模型在训练和术前规划中的价值。

背景：3D打印的出现彻底改变了医疗培训和术前规划。然而，现有模型存在局限性，促使新设计的柔性3d打印骨折模型的发展。方法：133名不同经验水平的创伤外科医生对所设计的柔性3d打印骨折模型进行评估，以评估其作为教育工具或术前计划工具的感知价值。结果：模型允许钻孔，对操作和灭菌具有抵抗性。外科医生发现灵活的模型有助于教学和计划骨折复位，计划和模拟骨整合，理解骨折，可视化骨折以及计划手术入路。结论：灵活的3d打印骨折模型为了解复杂骨折提供了动态和现实的方法，有可能改善手术训练和术前计划。
