Abstract:

Objective To explore the efficacy of 3D printing technology combined with unilateral biportal endoscopy (UBE) surgical video in clinical teaching of spinal surgery for standardized training of orthopedic residents.Methods From January 2023 to December 2023, 100 of standardized training of orthopedic residents were randomly divided into experiment group (n=50) and control group (n=50). The control group received the traditional orthopedic teaching mode, while the experiment group received the 3D printing technology combined with UBE surgical video. The teaching efficacy were evaluated through examinations and questionnaires.Results The scores of theoretical examination, practical examination and final examination of the experiment group were higher than those of the control group, and the differences between the two groups were statistically significant (79.4±7.5 vs. 73.8±9.2; 78.8±7.3 vs.73.7±8.7; 79.1±7.3 vs.73.8±8.8, P<0.05). At the same time, the overall excellent rate of clinical teaching assessment in experiment group was higher than that in control group (80.0% vs. 60.0%, P<0.05). The experiment group not only outperformed the control group in terms of overall satisfaction with the teaching mode (91.3±3.4 vs. 85.4±2.8), enhancing independent learning abilities (92.4±2.5 vs. 89.2±2.2), understanding key knowledge points (94.0±1.9 vs. 87.0±3.5), and problem-solving abilities (91.6±3.7 vs. 83.9±2.7), but also demonstrated higher fostering learning interest (93.0±2.0 vs. 85.8±3.8), which were statistically significant (P<0.05). There was no statistical significance between the two groups in the evaluation of teacher explanations (91.3±2.9 vs. 91.2±2.9, P>0.05).Conclusion In the teaching of spine surgery, 3D printing technology combined with UBE surgical video teaching mode has achieved good teaching results, which can effectively improve the quality of orthopedic residential training teaching and enhance satisfaction.
