3D打印技术在复杂关节周围骨折临床带教中的应用(1)
摘 要：目的 将3D打印教具应用于骨创伤科复杂关节周围骨折的临床教学中，探索该方法的教学效果。方法 随机抽取60名在长征医院骨创伤科轮转的上海住院医师规范化培训学员进入研究，随机分为试验组和对照组，每组30人。挑选典型的股骨髁、胫骨平台骨折病例，使用CT断层扫描，数字成像及3D打印技术制成3D树脂标本。对照组采用单纯常规教学法，试验组在此基础上结合3D打印标本进行临床带教。比较两组学员的基本资料和出科考试成绩。结果 两组学员经管患者数量、经管关节骨折患者数量和教学满意度评分比较，差异无统计学意义(P>0.05)。试验组出科理论考核成绩为(82.14±13.25)分，高于对照组的(64.47±11.12)分，差异有统计学意义(P<0.05)。结论 3D打印技术对复杂关节周围骨折教学效果有辅助促进作用，具有良好的教学应用前景。

Abstract：Objective The 3D printing teaching aid was applied to the clinical teaching of complex periarticular fractures in the trauma department of bone trauma， and the teaching effect of the method was explored.Methods 60 standardized training trainees of Shanghai resident physicians in bone trauma rotation in changzheng hospital were randomly selected to enter the study. They were randomly divided into experimental group and control group， 30 in each group. Typical cases of femoral condyle and tibial plateau fractures were selected and 3D resin specimens were prepared by CT tomography， digital imaging and 3D printing. The control group adopted the simple conventional teaching method， and the experimental group conducted clinical teaching combined with 3D printed specimens on this basis. To compare the basic data and test scores of the two groups. Results There was no statistically significant difference between the two groups in the number of patients with menstrual canal， the number of patients with menstrual canal joint fracture and the teaching satisfaction score (P>0.05). The theoretical assessment score of the test group was (82.14±13.25)， higher than that of the control group (64.47±11.12)，the difference was statistically significant (P<0.05). Conclusion 3D printing technology can assist and promote the teaching effect of complex periarticular fractures and has a good prospect of teaching and application.

3D打印概念最開始由Charles Hull在上世纪80年代提出并发明了相关技术，属快速成形技术的一种，是通过层层沉淀制作物件[1]。随着技术的进展，目前已实现3D物件的高精度、低成本、快速制作及在生物医学领域的发展[2-4]。除了可用于辅助手术策略、内植物制作及组织工程，3D打印另一个重要的医学应用是进行医学教育[5，6]。随着交通及经济的高速发展，高能量损伤导致的复杂骨折越来越常见。骨创伤是骨科的基础学科，骨折致伤机制复杂，骨折类型多变。复杂关节周围骨折相关内容的讲授一直是骨创科临床带教的难点[7]。本研究拟将3D打印教具应用于骨创伤科复杂关节周围骨折的临床教学中，探索该方法的教学效果。
