目的 分析3D手术训练系统在骨科住院医师规范化培训中髌骨骨折手术教学中的应用效果。 方法 采用试验对照方法,2022年9月至2023年9月,选取在华中科技大学同济医学院附属协和医院参加骨科住院医师规范化培训的24名学员为研究对象,采用随机数表法分为试验组和对照组。试验组12名学员采用3D手术训练系统教学,对照组12名学员采用传统方式教学。通过理论考核、实践考核和满意度调查3种方式评价教学效果。采用t检验和卡方检验进行数据分析。 结果 理论考核中,试验组学员的理论考核总成绩[(81.42±4.68)分]高于对照组学员[(75.42±6.52)分],差异具有统计学意义(t=2.59,P=0.017)。实践考核中,试验组学员和对照组学员的复位时间[(20.25±5.26)分钟比(23.67±4.83)分钟]、透视次数[(2.75±1.06)次比(3.00±1.28)次]、术中出血量[(97.92±10.10)毫升比(100.40±7.82)毫升]比较,差异均无统计学意义(均P>0.05);试验组学员的张力带时间[(32.92±6.20)分钟]少于对照组学员[(38.42±3.63)分钟],差异具有统计学意义(t=2.65,P=0.015);试验组学员手术总时间[(86.17±11.42)分钟] 少于对照组学员[(100.20±12.22)分钟] ,差异具有统计学意义(t=2.90,P=0.008)。对照组学员完成所有考核内容后参与试验组学员的课程学习,并参加满意度调查。满意度调查结果显示,22名(91.7%)学员“愿意推荐3D手术训练系统教学方法”,20名(83.4%)学员认为“3D手术训练系统教学方法令人印象深刻”。 结论 应用3D手术训练系统有助于提升骨科住院医师规范化培训学员对于髌骨骨折手术教学中理论知识掌握程度,并缩短手术总时间,同时具有较高的教学满意度和教学效果。

Objective To explore the effect of a 3D surgical training system in the teaching of patella fracture surgeries to orthopedic residents. Methods A total of 24 participants from the standardized residency training program at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from September 2022 to September 2023, were selected and assigned into two groups using a random number table method, with 12 in the experimental group receiving the course using 3D surgical training system and 12 in the control group receiving traditional instruction. The teaching effectiveness was evaluated using knowledge examination, skills assessment, and satisfaction surveys. T-tests and chi-square tests were used for data analysis. Results In knowledge examination, total scores for the experimental group were (81.42±4.68) and (75.42±6.52) for the control group, with a statistically significant difference (t=2.59,P=0.017). In skills assessment, there were no significant differences between the experimental group and the control group interms of the duration of fracture reduction was (20.25±5.26) minutes for experimental group and (23.67±4.83) minutes for control group , the number of fluoroscopies use was (2.75±1.06) times for experimental group and (3.00±1.28) times for control group, and intraoperative blood loss was (97.92±10.10) ml for experimental group and (100.40±7.82) ml for control group (P>0.05). The time taken for the tension band was (32.92±6.20) minutes for the experimental group and (38.42±3.63) minutes for the control group, a statistically significant difference (t=2.65, P=0.015). The overall surgical duration was (86.17±11.42) minutes for the experimental group and (100.20±12.22) minutes for the control group, with a statistically significant difference (t=2.90, P=0.008).After completing all assessment components, the control group participants joined the experimental group′s course and participated in a satisfaction survey.satisfaction survey showed that 22(91.7%) were willing to recommend the teaching method, and 20(83.4%) found the teaching method impressive. Conclusions The application of the 3D surgical training system helped improve the theoretical knowledge acquisition of orthopedic residents in patella fracture surgery training and reduced the overall surgical time, and achieved high levels of teaching satisfaction and effectiveness.
