摘要 目的通过MRI测量华南地区人股骨后髁角(PCA)及髁扭转角(CTA),为全膝关节置换术中股骨截骨及假体旋转定位提供解剖学参数。方法华南地区人正常膝关节100例,男女各50例,年龄22～73岁,平均40.2岁;按性别和侧别分4组,行股骨远端轴位MRI扫描,图像用Photoshop处理,测量PCA和CTA,比较两角的性别差异和侧别差异,分析两角度的相关性。结果男性PCA大于女性(P<0.001),无侧别差异(男性P=0.335,女性P=0.266);男性CTA大于女性(P<0.001),无侧别差异(男性P=0.231,女性P=0.719);PCA和CTA存在相关性:男性R2=0.323,P<0.001;女性R2=0.206,P=0.001。结论华南地区人PCA及CTA参数与华北地区人接近,均为男性大于女性,无侧别差异;PCA和CTA存在相关性;轴位MRI图像有利于PCA及CTA的准确测量。
