摘　　要：目的 比较3D打印仿真骨盆模型体外模拟术与常规CT辅助下手术治疗复杂骨盆骨折患者的效果及安全性。方法 研究对象为2018年6月-2021年6月郑州市中心医院收治的92例复杂骨盆骨折患者。根据随机数字表法分为观察组(n=46例)和对照组(n=46例)。对照组在CT引导下完成手术治疗,观察组行钢板内固定术联合3D打印仿真骨盆模型体外模拟术治疗。出院12个月后比较两组手术指标(骨折愈合时间、住院时间、术中出血量、手术时间、内固定松动、断裂、骨折移位)、疗效指标(Matta临床评分优良率及复位优良率)和安全性指标(骨性关节炎、疼痛、切口感染、其他脏器损伤、深静脉血栓、神经损伤等并发症发生率)。结果 观察组骨折愈合时间、住院时间、术中出血量、手术时间、内固定松动、断裂、骨折移位分别为(10.36±1.28)周,(7.12±1.54)d、(311.05±21.14)mL、(106.67±10.37)min、2.17%,2.17%,均明显低于对照组的(12.08±1.69)周、(8.67±1.61)d、(386.69±45.57)mL、(131.34±16.98)min、6.52%、4.35%,两组比较差异均有统计学意义(均P<0.05)。观察组Matta临床评分优良率为93.48%,明显高于对照组的78.26%,差异有统计学意义(χ^(2)=9.683,P<0.05)。观察组复位优良率为95.65%,明显高于对照组的78.26%,差异有统计学意义(χ^(2)=8.316,P<0.05)。出院6个月后观察组并发症发生率为2.17%,明显低于对照组的19.57%(χ^(2)=7.681,P<0.05)。结论 3D打印仿真骨盆模型体外模拟术治疗复杂骨盆骨折患者可提高手术效果,改善患者康复情况,提高安全性,值得临床推广应用。Objective To compare the efficacy and safety of 3D printing virtual pelvic model in vitro simulation and con-ventional CT assisted surgery in the treatment of complex pelvic fractures.Methods The subjects were 92 patients with complex pelvic fractures admitted to Zhengzhou Central Hospital from June 2018 to June 2021.Divided into an observa-tion group(n=46 cases)and a control group(n=46 cases)according to the order of admission.The control group completed the surgical treatment under the guidance of CT,and the observation group was treated with plate internal fix-ation combined with 3D printing simulated pelvic model in vitro simulation.Twelve months after discharge,the dffer-ences in surgical indicators(fracture healing time,hospital stay,intraoperative bleeding,operation time,internal fixa-tion loosening,fracture,fracture displacement),efficacy indicators(Matta clinical score excellent rate and reduction excellent rate)and safety indicators(osteoarthritis,pain,incision infection,other organ injury,deep vein thrombosis,nerve injury and other complications)were compared between the two groups.Results The fracture healing time,hos-pitalization time,intraoperative blood loss,operation time,internal fixation loosening,fracture and fracture displacement in the observation group were(10.36±1.28)weeks,(7.12±1.54)days,(311.05±21.14)mL,(106.67±10.37)min,2.17%and 2.17%respectively,which were significantly lower than those in the control group,(12.08±1.69)weeks,(8.67±1.61)d,(386.69±45.57)mL,(131.34±16.98)min,6.52%and 4.35%.There were significant differences between the two groups(all P<0.05).The excellent and good rate of Matta clinical score in the observation group was 93.48%,significantly higher than 78.26%in the control group,and the difference was statistically significant(χ^(2)=9.683,P<0.05)。The excellent and good rate of reduction in the observation group was 95.65%,significantly higher than 78.26%in the control group,and the difference was statistically significant(χ^(2)=8.316,P<0.05)。Six months after
