【摘要】：[目的]运用3D打印技术对成人发育性髋关节发育不良(developmental dysplasia of the hip,DDH)初次行人工全髋关节置换术(total hip arthroplasty,THA)的患者制定术前计划,探讨该技术对髋臼杯置入的作用。[方法]纳入贵阳市第四人民医院骨一科2015年1月~2016年12月收治的成人DDH患者38例(41髋),其中,3D组19例(20髋),常规组19例(21髋),3D组患者术前根据打印3D模型三维重建数据制定术前计划;常规组按常规计划完成手术方案设计。术后比较髋臼假体外展角、前倾角,水平及垂直距离与术前预计值的差异程度,评估髋臼假体的置入精度。[结果]两组间髋臼实际位置,包括外展角、前倾角、水平及垂直距离的差异均有统计学意义(P0.05)。3D组外展角、前倾角、水平及垂直距离的设计值和实际值差异度更小,更接近理想设计值。[结论]运用3D打印技术指导完成术前计划虽不能降低手术难度,但能优化术前设计,利于髋臼假体理想放置,增加假体置入精确度。
[Abstract]:[Objective] to use 3D printing technique to make a pre operation plan for the initial total hip arthroplasty (total hip arthroplasty, THA) for adult developmental hip dysplasia (developmental dysplasia of the hip, DDH) and explore the effect of this technique on the implantation of acetabulum cup. [method] included in the Guiyang Fourth People's Hospital bone one department in 2015. 38 adult DDH patients (41 hips) were treated in January ~2016. Among them, 19 cases (20 hips) in group 3D, 19 cases (21 hips) in the routine group, and group 3D were prepared before operation according to the 3D reconstruction data of 3D model. The routine group completed the operation plan according to the routine plan. The difference in the estimated value of the values of the acetabular prosthesis was evaluated. [results] the two groups of acetabular positions, including abduction angle, front angle, horizontal and vertical distance, were statistically significant (P0.05).3D abduction angle, the design values of the front angle, the horizontal and vertical distance were smaller and closer to the ideal value. [Conclusion] The use of 3D printing technology to guide the completion of preoperative planning can not reduce the difficulty of operation, but it can optimize the preoperative design, facilitate the ideal placement of acetabular prosthesis and increase the accuracy of implant placement.
