3D打印技术在复杂股骨粗隆间骨折的临床PBL教学中的应用

Application of 3D Printing Technique in PBL Teaching of Complicated Femoral Intertrochanteric Fractures

目的探讨3D打印技术在复杂股骨粗隆间骨折的临床PBL教学中的应用效果,以提高骨科临床教学的整体质量。方法纳入骨科临床专业学生共28名,随机数字法将学生分为传统教学法和新教学法(3D打印技术、PBL教学法)进行临床教学。通过实体讲解,而后再参观手术过程,比较两组教学方法的效果,包括学生的学习成绩、综合能力自我评估数据。结果与传统教学法组比较,新教学法组学生的学习成绩与综合能力自我评估分数显著提高,差异具有统计学意义(P<0.05)。结论采用3D打印技术、PBL教学法的新教学法在复杂股骨粗隆间骨折的临床教学中具有良好的教学效果。

Objective To explore the effect of3D printing technique in clinical PBL teaching of complex intertrochanteric fractures in order to improve the overall quality of orthopedic teaching.Methods A total of28students were included in the orthopedic clinical program.The random number method was used and the students were divided into2groups:traditional teaching method group and new teaching method group(3D printing technique,PBL teaching method).The teaching method was explained by the entity,and then the procedure was followed.The effects of the two groups of teaching methods were compared,including the student's academic performance,comprehensive ability self-assessment data.Results Compared with the traditional teaching method group,the scores of the new teaching method group were higher,and the difference was statistically significant(P<0.05).Conclusion The new teaching method of PBL teaching method with3D printing technique has good teaching effect in clinical teaching of complex femoral intertrochanteric fractures.
