Using 153Gd dualphoton absorptiometry, bone mineral density (BMD) was measured in three areas of the proximal femur-the femoral neck, Ward's triangle and the greater trochanter-in 129 females referred for possible osteoporosis. In addition, lumbar spine bone density was determined. Lumbar spine BMD was significantly greater than any regional proximal femoral BMD (p less than 0.0001). Ward's triangle was significantly less than the trochanteric region (p less than 0.01) and both Ward's triangle and the greater trochanter were significantly less than the femoral neck (p less than 0.0005). Correlations within the three regions of the proximal femur are considerably higher than those between the spine and the proximal femur regions. This suggests that measurement of all three areas of the proximal femur is not essential for a satisfactory assessment of proximal femoral mineral content. In particular, since Ward's triangle is strongly correlated with the greater trochanter and the femoral neck, it may rationally be excluded from analysis of proximal femoral bone density.
采用153钆双能X线吸收法，对129名疑似患有骨质疏松症的女性的股骨近端三个部位——股骨颈、沃德三角区和大转子——进行了骨矿物质密度（BMD）测量。此外，还测定了腰椎骨密度。腰椎骨密度显著高于股骨近端任何一个区域的骨密度（p<0.0001）。沃德三角区的骨密度显著低于转子区（p<0.01），沃德三角区和大转子的骨密度均显著低于股骨颈（p<0.0005）。股骨近端三个区域之间的相关性明显高于脊柱与股骨近端区域之间的相关性。这表明，对股骨近端所有三个部位进行测量对于满意评估股骨近端矿物质含量并非必不可少。特别是，由于沃德三角区与大转子和股骨颈密切相关，在分析股骨近端骨密度时可合理地将其排除。
