摘　　要：目的 将3D打印技术作为一种辅助教学工具应用于髋臼骨折的临床教学活动中,探讨其应用效果。方法 选取2020年1月—2022年1月于蚌埠医学院第一附属医院创伤骨科参加规范化培训的48名住院医师规范化培训医师(简称住培生)为研究对象,采用随机数字表法分为2组,每组24人。试验组采用3D打印技术联合传统教学模式进行教学,对照组仅采用传统教学模式进行教学。教学结束后分别对2组学生进行客观指标和主观指标评价,客观指标主要为理论知识考试成绩,采用多时间点的评价模式进行评价;主观指标评价采用不记名问卷调查模式,评价2组住培生在学习兴趣、理解能力、内容掌握、课程参与、案例分析能力、满意度方面的差异。结果 2组住培生课后即刻、课后1周理论考核得分比较,差异均无统计学意义(均P>0.05),课后1、2、4个月考核得分比较,试验组得分均高于对照组[(85.33±3.02)分vs.(82.33±2.60)分、(83.13±2.51)分vs.(79.21±2.75)分、(80.33±2.41)分vs.(75.71±2.82)分,均P<0.05];不同时间点住培生的理论考核成绩有差异,随着时间的延长理论考核得分下降(P<0.05),试验组住培生成绩下降平缓,而对照组成绩下降更明显。试验组在学习兴趣、理解能力、内容掌握、课程参与、案例分析能力、满意度方面得分均高于对照组(均P<0.05)。结论髋臼骨折的临床教学中,3D打印技术是一种有效的辅助工具,可以提升教学效果。Objective To apply 3D printing technology as an auxiliary teaching tool in clinical teaching activities of acetabular fractures,and explore its application effect.Methods Forty-eight residents who participated in the Orthopaedic training base of the First Affiliated Hospital of Bengbu Medical College from January 2020 to January 2022 were selected as research objects and divided into two groups by random number method,with 24 residents in each group.The resident in experimental group applied the 3D printing technology combined with traditional teaching model to study,while who in control group only accepted traditional teaching to study.After the course,subjective indicators and objective indicators were evaluated and compared for the two groups of residents.The objective indicators were evaluated and compared at multiple time points.Objective and subjective indicators were evaluated for the 2 groups of students respectively after the end of teaching.The objective indicators were mainly the theoretical knowledge examination results,which were evaluated using the evaluation mode of multiple time points;the subjective indicators were evaluated using the anonymous questionnaire mode,which evaluated the differences between the 2 groups of resident trainees in terms of interest in learning,comprehension,content mastery,course participation,case study ability,and satisfaction.Results There was no statistically significant difference in the objective scores of the two groups of resident trainees immediately and 1 week after course(all P>0.05),the objective scores of the experimental group in 1,2 and 4 months after course were higher than those of the control group[(85.33±3.02)points vs.(82.33±2.60)points,(83.13±2.51)points vs.(79.21±2.75)points,(80.33±2.41)points vs.(75.71±2.82)points,all P<0.05].There were differences in the objective scores of resident trainees at different time points,as evidenced by a statistically significant decrease in the objective scores over time(P<0.05).The decline in the objective scor
