Abstract：Objective To explore the clinical effect of 3D printing technology in the assisted treatment of unstable pelvic fractures.Methods The clinical data of 50 patients with unstable pelvic fractures admitted to Huiya Hospital of the First Affiliated Hospital,Sun Yat-sen University from January 2015 to December 2019 were retrospectively analyzed.According to the different treatment methods,they were divided into the routine group(n=25)and the study group(n=25).The routine group was treated with post erior approach,sacroiliac joint fixed with spinal pelvic fixation,and the study group was treated with 3D printing technique on the basis of routine group.The operative time,intraoperative bleeding volume,screw dislocation rate,fracture reduction quality,pelvic function recovery and complications were compared between the two groups.Results The operation time in the study group was shorter than that in the routine group,the intraoperative bleeding volume and screw dislocation rate of the study group were less than those of the routine group,the differences were statistically significant(P＜0.05).There was no significant difference in fracture reduction quality in the two groups(P＞0.05).There was no significant difference in the quality of pelvic function recovery in the two groups(P＞0.05).The total incidence of complications in the study group was lower than in the conventional group,and the difference was statistically significant(P＜0.05).Conclusion 3D printing technology in the assisted treatment of unstable pelvic fractures,pelvic fracture repair in advance to carry out accurate evaluation norms,help to shorten the operation time,reduce surgical trauma and complications,and has good fracture repair quality and functional recovery effect.
