Abstract

Abstract: Objective To implement and evaluate of 3D printing technology in undergraduates teaching of spinal surgery. Methods Selected fifty undergraduates of the 2015 five-year program during clerkship in our hospital from September to November 2019. They were randomly divided into two groups by the random number table,with 25 persons in each. The experimental group used 3D stereo models plus group discussion systems. The control group used traditional cadaver specimens plus plaster models. Compared and analyzed the examination results of spine surgery of the two groups students, and used questionnaires to investigate their evaluation of teaching effects. Results The scores of class test [(87.06±2.74) vs (72.45±3.61)], final examine test [(83.30±2.94) vs (75.95±3.23)] and operation test [(85.10±2.86) vs (77.20±3.29)] were higher in the experimental group than those in control group(all P<0.05). The experimental group significantly outscored the control group in learning interesting [(7.67±1.23) vs (6.00±1.69)],class interaction [(7.53±1.35) vs (6.13±1.18)], learning efficiency [(8.53±0.91) vs (6.87±1.06)]and disease awareness[(8.86±0.92) vs (7.40±1.05)], operational mastery [(8.40±0.94) vs (7.00±1.03)], teaching satisfaction [(9.00±0.76) vs (8.00±0.85)] (all P<0.05). Conclusions The 3D printing technology can effectively mobilize students' enthusiasm, significantly and active thinking so improved teaching effect in undergraduate training of spine surgery, which helps students to master clinical knowledge in a solid way.
