摘要(Abstract)：
[目的]验证在初次人工全髋关节置换时,使用自制髋臼假体角度导向器辅助安装,对提高髋臼假体置入角度准确率的影响和临床疗效。[方法]90例(98髋)进行全髋关节置换术,设定髋臼最佳置入外展角为40°,前倾角为20°。患者随机分导向器组(50髋)和对照组(48髋),其中导向器组手术中采用自制金属髋臼假体安装导向器辅助下进行髋臼假体的安放,对照组则采用传统手术,没有借助任何定位导向安装设备,完全靠徒手安装。术后拍骨盆前后位X线片测量髋臼假体角度,并将测量的外展角与前倾角数据进行分析,评估两种方法安放髋臼假体的准确性。[结果]导向器组:手术中安装导向器时间为40 s~1 min 30 s,髋臼前倾角为14.54°±5.25°,外展角为41.82°±3.61°;对照组前倾角为17.49°±8.47°,外展角为39.26°±7.19°。将外展角、前倾角均值分别进行比较,差异具有统计学意义(P<0.05)。[结论]髋臼角度导向器可以提高置入髋臼假体的准确性,术中操作方便,安装导向器耗时短,可以反复使用,具有重要的临床价值。
