【摘要】：目的探索3-D打印个性化髋关节精确制备模板在全髋关节置换中的应用。方法纳入行首次全髋关节置换的患者40例,分为模板组20例和常规组20例。模板组术前行髋关节三维CT扫描,获取患者CT原始数据资料,应用Mimics16.0软件建立患者髋关节模型,模拟THA手术过程并设计手术相关的患者个性化的制备模板,利用3-D打印机以Visijet M3 Crystal为材料打印出制备模板,将模板应用于THA中,常规组不应用模板。比较两组患者的临床结局,探究3-D打印个性化制备模板应用在全髋关节置换术中的作用。结果两组患者在一般资料、术前Harris评分、术前髋臼解剖数据方面无明显差异。模板组在髋臼外展角偏离值和前倾角偏离值、颈干角偏离值、双下肢不等长发生率方面明显低于常规组,但是在手术时间、术中出血量、术后4周Harris评分方面模板组与常规组无明显统计学差异。结论借助3-D打印制备的患者个性化制备模板在全髋关节置换术中可获得一定精确性,有利于假体安放在与术前计划匹配位置,提高手术质量。
[Abstract]:Objective to explore the application of 3-D printed personalized hip precise preparation template in total hip arthroplasty. Methods 40 patients with first total hip replacement were included. The patients were divided into two groups: the template group (n = 20) and the routine group (n = 20). Three dimensional CT scanning was performed before operation in the template group, the original CT data of the patients were obtained, and the hip joint model was established by Mimics16.0 software. The process of THA operation was simulated and the individualized template was designed. The template was printed out by 3-D printer with Visijet M3 Crystal. The template was used in THA, but not in the routine group. The clinical outcomes of the two groups were compared. Objective: to explore the role of 3-D printed personalized template in total hip arthroplasty. Results the patients in both groups were evaluated with general data and preoperative Harris score. There was no significant difference in the anatomic data of acetabular before operation. The deviation value of acetabular abduction angle, anteversion angle, neck shaft angle, and the incidence of unequal length of both lower limbs in the template group were significantly lower than those in the routine group, but the operative time and the amount of blood lost during operation were significantly lower in the template group than in the conventional group. There was no significant difference in Harris score between the template group and the routine group 4 weeks after operation. Conclusion the individualized template made by 3-D printing can obtain certain accuracy in total hip arthroplasty. It is beneficial for the prosthesis to fit with the preoperative plan and to improve the quality of the operation.
