摘　　要：基于计算机辅助导航(CANS)与非导航术式(MANS)的髋关节置换术临床数据,采用Mimics和Matlab编程构建植入髋臼杯定位精度测量方法。经对50例CANS与MANS髋关节置换髋臼杯前倾角和外展角进行测量与统计。结果表明,采用CANS进行全髋置换时,髋臼杯定位精度高于MANS方式,髋臼杯定位处于安全范围的几率大于MANS方式。CANS可以很好地提高髋臼杯假体植入的精确度,有效降低术后关节脱位发生的几率。To contrast the methodology of measuring cup placement precision utilizing Mimics and Matlab programming, based on clinical CT images of primary THA cases with computer assisted navigated surgery （CANS） and with the traditional manual method （MANS）. The method was applied and anaylzed to measure cup anteversion, cup abduction of 50 clinical cases with CANS and MANSThe results show that, cup placement precision differences exits between primary THA cases with CANS and MANS; more cases with CANS are within the safe zone contrasting MANS, and there was less variation and less placement error in CANS cases. CANS can improve cup placement precision and reduce the chance of dislocation efficiently.
