A simulation and model (SM) teaching aid using 3D printing was developed to improve a training course for total hip arthroplasty of adult developmental dysplasia of the hip (adult DDH-THA). We named this new method Surgery Simulation Teaching based on a Real Reconstruction Aid (RRA-SST). A prospective randomized comparison was performed with the traditional surgical live teaching method to evaluate the training effectiveness of RRA-SST for adult DDH-THA.
Twenty-six trainees, who were already practicing but were not experienced, participated in the study. We randomly divided the trainees into two groups: Group A (n = 13) received RRA-SST and group B (n = 13) received traditional surgical live teaching. A surgery simulation test and a questionnaire were used for evaluation. Next, each group received training with the other teaching method, and then the test and questionnaire were used again for evaluation.
After the first test, the RRA-SST method was shown to produce better results than the traditional surgical live teaching method. After the second test, the results showed the training effect in both groups reached the same level, which was level as Group A RRA-SST results. Analysis of the questionnaire results showed that the training effect of RRA-SST was higher than that of traditional surgical live teaching, from multiple perspectives.
The use of RRA-SST improved participant performance according to simulation assessment. RRA-SST can be helpful for trainees who are already practicing but not experienced when developing proficiency in adult DDH-THA surgical techniques.
开发了一种使用3D打印的模拟与模型（SM）教具，以改进成人发育性髋关节发育不良全髋关节置换术（成人DDH - THA）的培训课程。我们将这种新方法命名为基于真实重建辅助的手术模拟教学（RRA - SST）。与传统的手术现场教学方法进行前瞻性随机比较，以评估RRA - SST对成人DDH - THA的培训效果。
26名已从业但经验不足的学员参与了研究。我们将学员随机分为两组：A组（n = 13）接受RRA - SST，B组（n = 13）接受传统的手术现场教学。使用手术模拟测试和问卷调查进行评估。接下来，每组接受另一种教学方法的培训，然后再次使用测试和问卷调查进行评估。
第一次测试后，RRA - SST方法显示出比传统手术现场教学方法更好的结果。第二次测试后，结果显示两组的培训效果达到相同水平，与A组RRA - SST结果相当。对问卷调查结果的分析表明，从多个角度来看，RRA - SST的培训效果高于传统手术现场教学。
根据模拟评估，使用RRA - SST提高了参与者的表现。RRA - SST对于已从业但经验不足的学员在掌握成人DDH - THA手术技术的熟练程度方面可能会有所帮助。
