摘　　要：[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。[ Objective] To measure the anatomical parameters of hip of healthy people in South China on CT three - di- mensional （3D） reconstruction images, and provide evidence for the design and implantation of the prosthesis. [ Methods] CT scans were performed on 80 healthy volunteers （160 hips） from South China, including 40 males （80 hips） and 40 females （80 hips） . The average age was （31.38 ± 8. 49） years, the average weight was （59.99±8.53 ） kg, and the average height was （ 167.25 ± 8.56） cm. The images were imported into Mimics 10. 01 to perform 3D reconstruction, and to measure the parameters of acetabula and proximal femur. [ Results ] The mean （SD） of AVA, ABA, CE and SID were （ 20. 09± 2. 56）°, （49. 32 ± 3.77 ）°, （ 33.46 ± 4.23 ）° and （ 58.74± 4.20） mm, separately. There were significant differences of ABA and SID between the two genders, while no significant differences of AVA and CE was found. The mean （SD） of the femoral anteversion angle, neck - shaft angle, diameter of the femoral head, offset, medial - lateral diameter and antero - posterior diameter of bone medul- lary cavity at the plane of 20 mm above, midpoint, and 20 mm below the lesser trochanter, the position of isthmus, the internal and external diameter of the isthmus, and the canal flare index were （ 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）, separately. There were significant differences of the above parameters between two genders except for neck - shaft angle, me- dial -lateral diameter at the midpoint of LT, and the position of isthmus. [ Conclusion] There are differences of acetabular ana- tomical parameters between healthy people in South China and other areas. Compared with the occidental, the Chinese femurs are
