摘　　要：目的探讨国人正常股骨近端参数的特点,为国产假体的设计和研究提供解剖学依据。方法随机抽取100例正常国人髋关节前后位CR片,由Unisight医学图像处理软件测量股骨头直径、颈长、颈干角、偏心距、股骨头垂直高度、干骺端宽度T+20、TO、T-20、峡部直径、峡部高度、髓腔闪烁指数和干骺端髓腔闪烁指数等参数,并与国内学者测量的以及欧美人股骨参数进行比较。结果本组国人正常股骨大体形态学参数与Noble、Massin等所测欧美人的股骨参数几乎都有差别,特别是偏心距、股骨头垂直高度、干骺端宽度T+20、TO、T-20、峡部直径、股骨头直径等参数差别较大。本组测量的漏斗状股骨占20%,远高于Noble、Massin等测量欧美人的8%和11.5%,差异有高度统计学意义(P<0.01),而与国内刘勤等测量的国人股骨形态差异无统计学意义(P>0.05)。结论CR系统便于对股骨近端大体形态的研究以及参数的测量,可用于人群股骨形态的普查;建立股骨近端参数的数据库对设计符合国人解剖特点的股骨假体十分重要。Objective To explore the characteristics of proximal femoral parameter in the healthy Chinese and provide anatomic basis for the design and research of the domestic prosthesis. Methods One hundred computed radiographs perpendicular to the hip joint were selected randomly and the proximal femoral parameter were measured by means of Unisight software. These parameters include diameter of femoral head, length of femoral neck, neck-shaft angle, offset, high of femoral head, the width of bone medullary cavity at the plane of lesser trochanter, 20mm above and below the lesser trochanter, diameter and height of the narrow cavity, canal flare index（CFI） and metaphyseal canal flare index （MCFI）. The proximal femoral parameters among the Chinese, American and European were compared. Results There were significant differences in the proximal femoral parameters between ours and American and European, especially in aspect of offset, height of femoral head, diameter of femoral head, the width of bone medullary cavity at the plane of lesser trochanter,20mm above and below the lesser trochanter and diameter of the narrow cavity. The percentage of funnel-shaped femora （CFI〉4.7） in our group was larger than that of the American or the European （P〈0.01）,which was 20%, 8%, andll.5% respectively, but there was no significant difference between ours and other domestic scholar＇s. Conclusion Computed radiograph system facililates to the research of the morphology of the proximal femur and the measurement of relative parameters and the survey of the characteristics of Chinese femoral. It is imporrant for research and manufacture of the domestic prosthesis fitting the features of the femurs of the Chinese femoral to set up a database of the healthy Chinese proximal femora.
