The broadband ultrasound attenuation (BUA) of the right calcaneus was measured in 49 women with Colles' fracture, in 36 women with hip fracture, and in 77 normal women. All were postmenopausal, and the fractures were all of fragility type. BUA correlated with age only in the normals. BUA distinguished between the fracture cases with sensitivities of 97 percent and 70 percent and specificities of 72 percent and 92 percent at 61 dB/MHz and 51 dB/MHz, respectively. The women with hip fracture had lower BUA than those with Colles' fracture. For screening purposes, BUA below 51 dB/MHz may arouse suspicion of a fracture risk, notably if other factors such as a tendency to fall, dietary and other habits, inactive lifestyles and early menopause are present.
对49例柯莱斯骨折女性、36例髋部骨折女性和77例正常女性测量了右侧跟骨的宽带超声衰减（BUA）。所有女性均为绝经后，且骨折均为脆性骨折类型。仅在正常女性中，BUA与年龄相关。在61dB/MHz和51dB/MHz时，BUA区分骨折病例的敏感度分别为97%和70%，特异度分别为72%和92%。髋部骨折女性的BUA低于柯莱斯骨折女性。为了进行筛查，低于51dB/MHz的BUA可能会引起对骨折风险的怀疑，特别是如果存在其他因素，如跌倒倾向、饮食和其他习惯、不活跃的生活方式以及过早绝经。
