Application of personalized navigation template in hip arthroplasty
-
摘要:
目的 依据髋臼的解剖形态制作个性化的导航模板，观察其在全髋关节置换术中应用的效果。 方法选择2014年3~11月期间，在福建医科大学附属泉州第一医院行全髋关节置换术的15位病人，根据围手术期间是否使用数字化导航模板分为实验组(n=8)和对照组(n=7)。评价两组病人手术时间、术中出血量、术后影像学指标。所有患者，术后均随访3个月以上。 结果与对照组相比较，实验组平均手术时间缩短，术中出血量少，但没有统计学上差别；实验组髋臼假体的前倾角及外展角与髋臼前倾角及外展角吻合性较好，两种方法在髋臼假体型号选择方面差别无统计学意义。 结论数字化导航模板的应用可提高全髋关节置换手术效率，减少手术风险，提高假体放置的准确性。 Abstract:ObjectiveTo create personalized navigation template and observe the effect of arthroplasty applications. MethodsIn March 2014-November 2014 period,patients of First Affiliated Hospital of Fujian Medical University, Quanzhou with total hip arthroplasty, according to the intraoperative use the digital navigation templates divided into a experimental group (n = 8) and a control group(n = 7).Intraoperative assessment of operative time, blood loss, postoperative radiographic review comparing.All patients were followed up for 3 months or more. ResultsCompared with the control group, the experimental group patients shorter operative time, less blood loss, but the difference was not statistically . The anastomosis of anteversion and abduction angle of acetabular prosthesis and acetabular hip was much bettber.There was no statistically difference in the two methods in the acetabulum prosthesis selection. Conclusion Application of digital navigation templates can improve the efficiency of total hip replacement surgery, reducing surgical risks, improve the accuracy of prosthesis placement. -
