AbstractQuantitative ultrasound (QUS) is emerging as a simple, inexpensive and noninvasive method for assessing bone quality and assessing fracture risk. We assessed the usefulness of a contact calcaneal ultrasonometer by studying normal premenopausal women (group I, n = 53), normal postmenopausal women (group II, n = 198), and osteoporotic women without (group III, n = 141) and with vertebral fractures (group IV, n = 53). The osteoporotic subjects had a T-score of the spine or hip neck bone mineral density (BMD) < -2.5 based on the local Chinese peak young mean values. When compared with postmenopausal controls, mean broadband ultrasound attenuation (BUA), speed of sound (SOS), and quantitative ultrasound index (QUI) were 26%, 2.1% and 25% lower in women with vertebral fractures (p all < 0.095). The correlation coefficients between QUS parameters and BMD of the spine and hip ranged between 0.4 and 0.5. The ability of the QUS to discriminate between patients groups was determined based on the mean value of normal premenopausal women in group I. The mean T-score for women with fractures was -2.87 ± 1.02 for BUA, -2.54 ± 0.79 for SOS, -3.17 ± 0.70 for QUI, -2.65 ± 0.86 for L2-4, BMD and -2.53 ± 0.66 for hip neck BMD. After adjustment for age and body mass index, the odds ratio of vertebral fracture was 1.71 (95% CI 1.2-2.6) for each 1 SD reduction in BUA, 2.72 (1.3-5.3) for SOS, 2.58 (1.4-4.6) for QUI, 2.33 (1.6-3.3) for L2-4 BMD, 2.09 (1.37-3.20) for femoral neck BMD and 1.88 (1.34-2.92) for total hip BMD. The association between the QUS parameters and vertebral fracture risk persisted even adjustment for BMD. The area under the receiver operating characteristic curve for BUA for vertebral fracture was 0.92, for SOS, QUI, L2-4 BMD and femoral neck BMD was 0.95, and for total hip was 0.91.
