Bottom Line: Students in the 3 Dp or 3D group performed significantly better than those in the CT group, although males in the 3D group scored higher than females.Students in the 3 Dp group were the first to answer all questions, and there were no sex-related differences.Pleasure, assistance, effect, and confidence were more predominant in students in the 3 Dp group than in those in the 3D and CT groups.

ABSTRACT
Three-dimensional printing (3 Dp) is being increasingly used in medical education. Although the use of such lifelike models is beneficial, well-powered, randomized studies supporting this statement are scarce. Two spinal fracture simulation models were generated by 3 Dp. Altogether, 120 medical students (54.2% females) were randomized into three teaching module groups [two-dimensional computed tomography images (CT), 3D, or 3 Dp] and asked to answer 10 key anatomical and 4 evaluative questions. Students in the 3 Dp or 3D group performed significantly better than those in the CT group, although males in the 3D group scored higher than females. Students in the 3 Dp group were the first to answer all questions, and there were no sex-related differences. Pleasure, assistance, effect, and confidence were more predominant in students in the 3 Dp group than in those in the 3D and CT groups. This randomized study revealed that the 3 Dp model markedly improved the identification of complex spinal fracture anatomy by medical students and was equally appreciated and comprehended by both sexes. Therefore, the lifelike fracture model made by 3 Dp technology should be used as a means of premedical education.

Mentions: All students completed their basic training by learning anatomy not only through textbooks and dissecting corpses but also through computer simulations in anatomy during their first or second year of enrollment in Binzhou Medical University. First, a lecture was given to the students, describing the spinal anatomy, and the definition of normal cervical and thoracic vertebra segments was presented using PowerPoint. Further, a short technical description of the teaching module (TM) was provided for helping the students in successfully completing the teaching process (Fig. 1).
