摘要(Abstract)：

[目的]本研究旨在测量华南地区正常成人的股骨近段形态学参数,为假体设计及置入提供参考。[方法]招募华南地区正常成人志愿者80例(160髋),对志愿者髋关节行薄层螺旋CT扫描后,使用Mimics 10.01重建出三维模型,分别测量髋臼侧和股骨侧影响关节置换的解剖参数。[结果]华南地区正常成年人髋臼AVA、ABA、CE、SID的测量结果分别为(20.09±2.56)°、(49.32±3.77)°、(33.46±4.23)°以及(58.74±4.20)mm;不同性别之间,ABA、SID具有显著性差异,而AVA、CE则无显著性差异。股骨侧股骨前倾角、颈干角、股骨头直径、偏心距、小转子中点上方20 mm处髓腔内外径及前后径、小转子中点处髓腔内外径及前后径、小转子中点下方20 mm处髓腔内外径及前后径、峡部位置、峡部髓腔内径及外径的测量结果分别为(16.47±2.72)°,(129.61±10.32)°,(45.22±3.61)mm,(37.16±3.85)mm,(41.69±4.43)mm,(31.00±3.29)mm,(25.62±4.02)mm,(23.91±3.46)mm,(19.78±2.43)mm,(17.50±3.05)mm,(106.60±5.61)mm,(9.34±1.68)mm,(25.50±2.32)mm,(4.59±0.84)mm;不同性别之间,除颈干角、小转子中点处髓腔内外径、峡部位置等指标外,其余指标的差异有统计学意义。[结论]华南地区正常成年人的髋臼形态较国外及国内其他地区存在差异。近段股骨形态与国内其他地区相比存在一定差异;与欧美国家相比,颈干角较大,偏心距较小,近段股骨形态整体偏细,峡部位置距离小转子较近且峡部更狭窄。
