Abstract:
Objective To evaluate the clinical value of 3D printed modeling used to assist internal fixation for pelvic fractures.Methods The databases,Pubmed,EMBase,Cochrane library,CNKI,Wanfang and VIP,from initiation till August 2018,were searched for the controlled studies comparing surgery assisted by 3D printed modeling and conventional surgery in the treatment of pelvic fractures.The 2 groups were compared in terms of surgical time,blood loss,Matta score for reduction,Majeed score for functional recovery and complications.This meta-analysis was performed using software RevMan 5.3.Results A total of 6 relative controlled studies were included for this analysis involving 513 patients.There were 221 cases in the 3D printed modeling group and 292 ones in the conventional group.Our Meta-analysis showed that there were significant differences between the 2 groups in surgical time (MD =-48.11,95％ CI:-74.16 ～-22.06,P ＜0.05),blood loss (MD=-250.63,95％ CI:-337.42～-163.84,P ＜0.05) and Matta score for reduction (OR =1.85,95％ CI:1.07 ～ 3.20,P =0.03),favoring the 3D printed modeling group.No statistically significant difference was found between the 2 group in the rate of complications (OR =0.61,95％ CI:0.32 ～ 1.17,P =0.14).Conclusion Assistance with 3D printed modeling may help the surgery for pelvic fractures to shorten surgery time,decrease blood loss and improve reduction quality.
