摘　　要：目的:探讨运用3D打印技术辅助治疗股骨髁间骨折的临床疗效。方法:选取2015年1月至2015年9月温州医科大学附属第二医院育英儿童医院收治的48例股骨髁间骨折患者,随机分为试验组和对照组。试验组术前采用Mimics软件进行骨折重建及复位,再利用3D打印技术打印模型进行术前设计,对照组采用常规切开复位内固定治疗。记录2组患者手术时间、术中出血量、术中透视次数,采用HSS标准评价膝关节功能。结果:试验组患者手术时间为(61.25±14.28)min,与对照组的(79.14±18.43)min比较明显缩短,术中失血量为(81.74±23.50)m L,与对照组的(106.80±22.75)m L比较明显减少,术中透视次数为(2.10±0.50)次,与对照组的(4.10±0.70)次比较亦明显减少,差异均有统计学意义(P<0.05)。术后1年随访,试验组膝关节功能优于对照组(P<0.05)。结论:利用3D打印技术辅助治疗股骨髁间骨折能节省手术时间,减少术中出血量和透视次数,相对传统治疗方案能获得更好的临床疗效。Objective： To investigate the clinical outcome of three-dimensional printing technique for the treatment of femoral intercondylar fractures. Methods： Forty eight patients with femoral intercondylar fractures between January 2015 and September 2015 were randomly divided into treatment group and control group. Mimics software was used to reconstruct fracture model and reduction in treatment group, and preoperative plan was designed based on 3D printing model. Control group＇s patients underwent traditional treatment. The surgery duration, blood loss, fluoroscopy time and HSS score were collected. Results： The surgery duration in treatment group （61.25±14.28） min was shorter than that in the control group （79.14±18.43） min, blood loss in treatment group （81.74±23.50） mL was less than that in the control group （106.80±22.75） mL while fluoroscopy time also showed better performance （2.10±0.50 vs. 4.10±0.70）, and there was significant difference between two groups （P〈0.05）. After one-year follow up, the knee function in treatment group was better than that in the control group （P〈0.05）. Conclusion： Three-dimensional printing technique for the treatment of femoral intercondylar fractures can save surgery duration, reduce blood loss to certain extent, and obtaine better clinical outcome compared to traditional treatment.
