【Abstract】 Objective To evaluate the effect of 3Dbody software combined with problem-based learning（PBL）teaching method in the orthopedics teaching. Methods Clinical undergraduates of grade 2013 at the same class were divided into two groups. Undergraduates of experimental group were taught by 3Dbody software combined PBL teaching，and the problem was designed and the method of using 3Dbody software was given to students；Undergraduates of control group were taught by traditional teaching methods using textbooks and courseware. Degree of satisfaction of the undergraduates and examination scores were compared between two groups immediately after class and probation. Results The degree of satisfaction of the undergraduates（9.2±0.8）were significantly higher than control group（7.2±1.3）

and examination scores of experimental group(84.6±5.9 and 17.7±2.1) were significantly higher than control group（73.2±6.1 and 12.7±1.9）

and the difference was statistically significant（P＜0.05）. Conclusion　3Dbody software combined PBL can improve the effect of the orthopaedic teaching and enhance the student's interest. It should be generalized.
