摘　　要：目的 观察3D打印技术辅助切开复位内固定手术治疗Tile C型骨盆骨折的临床疗效。方法 回顾性分析自2018-04—2022-05行切开复位内固定术治疗的40例Tile C型骨盆骨折,其中20例术前应用3D打印技术和计算机辅助(Mimics 17.0)模拟手术(观察组),20例采用传统手术入路切开复位锁定钢板内固定术(对照组),比较两组手术时间、术中出血量、术中透视次数、置钉错位率、复位质量、术后并发症发生率、骨盆功能恢复情况差异。结果 观察组手术时间、术中出血量、术中透视次数、置钉错位率均优于对照组,差异有统计学意义(P<0.05)。观察组复位质量优7例,良12例,可1例;对照组复位质量优6例,良8例,可4例,差2例;两组复位质量情况差异无统计学意义(Z=-1.270,P=0.204)。观察组术后神经损伤1例、躯体移动障碍1例,对照组术后神经损伤1例、下肢深静脉血栓形成1例、感染2例、躯体移动障碍2例,两组术后并发症发生率差异无统计学意义(P=0.235)。40例术后至少随访12个月,两组术后3、6、12个月Majeed评分均高于术前,差异有统计学意义(P<0.05);观察组术后3、6、12个月Majeed评分均高于对照组,差异有统计学意义(P<0.05)。结论 3D打印技术辅助切开复位内固定术治疗Tile C型骨盆骨折的临床疗效满意,3D打印技术可以在术前模拟手术、为患者提供更具个性化的治疗方案,手术更高效、更安全,值得临床推广应用。Objective To analyze the therapeutic effect of three-dimensional(3D) printing technology assisted open reduction and internal fixation for Tile C-type pelvic fractures.Methods A retrospective analysis was performed on 40 cases of Tile Ctype pelvic fractures treated with open reduction and internal fixation surgery from April 2018 to May 2022.Among these,20cases were treated with 3D printing technology and computer-assisted(Mimics 17.0) simulated surgery(observation group),and 20 cases with traditional surgical approach open reduction and locking plate internal fixation surgery(control group).The operation time,intraoperative blood loss,intraoperative fluoroscopy frequency,screw misplacement rate,reduction quality,postoperative complication rate,and pelvic function recovery were recorded and compared between the two groups.Results The observation group had better operation time,intraoperative blood loss,intraoperative fluoroscopy frequency,and screw misplacement rate than the control group,and the differences were statistically significant(P<0.05).In the observation group,7 cases had excellent reduction quality,12 cases good,and 1 case fair.In the control group,6 cases had excellent reduction quality,8 cases good,4 cases fair,and 2 cases poor,no statistically significant difference in the reduction quality between the two groups(Z=-1.270,P=0.204).There was 1 case of postoperative nerve injury and 1 case of body movement disorder in the observation group while in the control group there was 1 case of postoperative nerve injury,1 case of lower limb deep vein thrombosis,2cases of infection,and 2 cases of body movement.There was no statistically significant difference in the incidence of postoperative complication rate between the two groups(P=0.235).Forty cases were followed up for at least 12 months after surgery,the Majeed scores at 3,6,and 12 months after surgery were higher than those before surgery in both groups,with statistical significance(P<0.05).The Majeed scores of the observation group were higher than th
