Objective　To explore the feasibility and superiority of applying digital orthopedic technology of virtual human reconstruction and 3D printing to CBL teaching of kyphosis for clinical postgraduates. Methods　Thirty postgraduates of professional degree participated in the standardized training of resident doctors in our department were randomized into the experimental group (New CBL teaching mode group) and the control group (traditional teaching mode group) with 15 students in each group

and the two groups were taught differently (the teaching content was two typical cases of kyphosis). Among them

the experimental group adopted the new CBL teaching mode

and successively conducted small class theory teaching

model explanation

group discussion

preoperative design

surgery observation and specific questions and answers

etc. The control group only used the traditional method to teach theory in a large class. The teaching effect of the two groups was evaluated in t test by SPSS 25.0. Results　For the teaching of patients with ankylosing spondylitis and kyphosis

scores of the satisfaction with class interest

mastery of theoretical knowledge and understanding of operation plan in the experimental group were (9.4±0.2)

(91.1±3.8)

and (91.5±3.5) respectively

and those in the control group were (8.2±0.4)

(82.1±3.5) and (83.1±4.7) respectively

with statistical significance (P<0.05). Conclusion　In the teaching of kyphosis

the CBL teaching mode based on digital orthopedic technology is superior to the traditional teaching mode

which is conducive to improving clinical skills for students.
