3D打印联合以问题为基础的教学法在创伤骨科住院医师培训中的应用

Objective To explore the educational value of combining 3D printing models with problem-based learning(PBL) in the standardized residency training of traumatic orthopedics, with the aim of optimizing the teaching model and providing practical evidence for clinical education reform. Methods From February 2023 to November 2024, 80 residents who received standardized training in the department of traumatic orthopedics, Affiliated Hospital of Xuzhou Medical University were randomly divided into experimental group and control group, with 40 cases in each group. The experimental group adopted 3D printing model combined with PBL teaching method, while the control group adopted traditional PBL teaching method. The teaching effect, subjective evaluation of teaching and comprehensive ability of doctors were compared between the two groups. Results The experimental group scored higher in various assessment items of teaching effectiveness than the control group(P<0.05). The experimental group scored higher in subjective evaluation of teaching than the control group(P<0.05). After training, the experimental group physicians scored higher in various abilities than the control group(P<0.05). Conclusion The combination of 3D printing models and PBL teaching method can enhance the intuition and practicality of traumatic orthopedics teaching, effectively improve the comprehensive abilities of resident physicians, and is worthy of promotion and application.
