摘　　要：目的:探讨利用3D打印技术测量发育性髋关节脱位儿童股骨颈前倾角的方法及准确性以期找到准确测量该类患儿股骨颈前倾角的方法并指导制定手术方案。方法:纳入2016年6月至2018年9月需行手术治疗的单侧发育性髋关节脱位患者17例,男2例,女15例;年龄2~13(5.47±0.81)岁;左侧11例,右侧6例。用CT测量法(CT法)、3D打印的股骨实物模型测量法(模型法)和术中股骨颈前倾角测量法(术中法)分别测量患儿股骨颈前倾角,以术中法测量值作为标准参考值,进行统计学分析,比较前两种测量方法的准确性。结果:CT法测量平均值为(36.00±1.66)°,模型法测量平均值为(43.91±1.62)°,术中法测得股骨前倾角平均值为(44.21±1.62)°。CT法测量值与模型法测量值、术中法测量值的比较差异均有统计学意义(P<0.05)。模型法测量值与术中法测量值差异无统计学意义(P>0.05)。结论:利用3D打印技术的模型法测量儿童发育性髋关节脱位股骨颈前倾角与传统CT测量法相比更简单、准确、可重复性强,而且可以术前模拟术中操作,是目前比较理想的测量股骨颈前倾角的方法。Objective:To explore the method and accuracy of measuring the femoral neck anteversion in children with developmental dislocation of the hip by using 3 D printing technology,so as to find out the method of measuring the femoral neck anteversion accurately and guide the formulation of the operation plan.Methods:From June 2016 to September 2018,17 patients with unilateral developmental dislocation of the hip were enrolled in the study,including 2 males and 15 females,aged 2 to 13(5.47±0.81)years old,11 on the left and 6 on the right.The methods of CT,3 D printing and intraoperative anteversion of femoral neck were used to measure the anteversion of femoral neck respectively.The intraoperative measurement was used as the standard reference value for statistical analysis,and the accuracy of the first two methods was compared.Results:The average value of CT was(36.00±1.66)°,the average value of model method was(43.91±1.62)°,and the average value of intraoperative method was(44.21±1.62)°.There were significant differences in CT measurement,model measurement and intraoperative measurement(P<0.05).There was no significant difference between model method and intraoperative method(P>0.05).Conclusion:Compared with the traditional CT method,the 3 D printing model method is simpler,more accurate and more repeatable,and can simulate the operation before operation.It is an ideal method to measure the femoral neck anteversion.
