3D打印技术对骨盆骨折治疗效果影响的Meta分析

目的:分析研究3D打印技术应用于骨盆骨折手术治疗的文献,评价3D打印技术对骨盆骨折手术治疗效果的影响。方法:检索Pub Med、Web of Science、中国生物医学文献数据库(CBM)、中国期刊全文数据库(CNKI)、中文科技期刊全文数据库维普(VIP)、万方数据库等,检索起止时间为从建库至2017年9月,收集应用3D打印技术于骨盆骨折术前规划的临床对照试验。按照事先制定的入选与剔除标准筛选文献,逐一评价纳入研究的质量,提取有效数据,采用Rev Man5.3软件进行Meta分析。结果:共纳入9个临床对照试验,共638例患者,其中3D打印技术组279例,常规组359例。Meta分析结果显示,3D技术组患者手术时间[SMD=-2.81,95%CI(-3.76,-1.85)],术中出血量[SMD=-3.28,95%CI(-4.72,-1.85)],术后并发症[OR=0.47,95%CI(0.25,0.87)]均明显小于常规组,而3D打印技术组在术后的骨盆骨折复位优良率[OR=2.09,95%CI(1.32,3.30)],骨盆功能优良率[OR=1.94,95%CI(1.15,3.28)]方面均优于常规组。结论:骨盆手术中应用3D打印技术具有缩短手术时间短、手术出血少、并发症少等优点,且能够提高骨盆骨折复位质量和促进术后骨盆功能恢复。

Effect of 3D printing technology on pelvic fractures:a Meta-analysis

Objective: To evaluate the effect of 3D printing technology applied in the surgical treatment of pelvic fractures through the published literatures by Meta-analysis.Methods: The PubMed database, EMCC database, CBM database, CNKI database, VIP database and Wanfang database were searched from the date of database foundation to August 2017 to collect the controlled clinical trials in wich 3D printing technology was applied in preoperative planning of pelvic fracture surgery. The retrieved literatures were screened according to predefined inclusion and exclusion criteria, and quality evaluation were performed. Then, the available data were extracted and analyzed with the RevMan5.3 software.Results: Totally 9 controlled clinical trials including 638 cases were chosen. Among them, 279 cases were assigned to the 3D printing technology group and 359 cases to the conventional group. The Meta-analysis results showed that the operative time[SMD=-2.81, 95%CI (-3.76, -1.85)], intraoperative blood loss[SMD=-3.28, 95%CI (-4.72, -1.85)] and the rate of complication[OR=0.47, 95%CI (0.25, 0.87)] in the 3D printing technology were all lower than those in the conventional group;the excellent and good rate of pelvic fracture reduction[OR=2.09, 95%CI (1.32, 3.30)] and postoperative pelvic functional restoration[OR=1.94, 95%CI (1.15, 3.28) in the 3D printing technology were all superior to those in the conventional group.Conclusion: 3D printing technology applied in the surgical treatment of pelvic fractures has the advantage of shorter operative time, less intraoperative blood loss and lower rate of complication, and can improve the quality of pelvic fracture reduction and the recovery of postoperative pelvic function.
