This study compares dual X-ray absorptiometry (DXA) measurements of the hip and spine with quantitative ultrasound (QUS) parameters measured simultaneously at the calcaneal and phalangeal bone in 174 patients with and without vertebral fractures. The aim of this study was to compare the ability of DXA and QUS measurements to discriminate patients with and without osteoporotic vertebral fractures and to evaluate whether QUS measurements in addition to the DXA measurements improve the clinical discrimination between patients with and without osteoporotic vertebral fractures. T-scores determined by DXA measurements at the spine and hip and QUS measurements at the calcaneus provide similar information regarding the discrimination of women with and without vertebral fractures. Phalangeal QUS measurements did not discriminate between patients with and without vertebral fractures. The discriminative power of the combined use of DXA and calcaneal QUS measurements to discern between patients with and without vertebral fractures increases in women. In contrast, the combined use of DXA and phalangeal QUS measurements resulted in decreased discriminative power as compared to DXA measurements alone. The number of fractures was higher in the quartiles with lower T-scores of the DXA and calcaneal QUS measurements whereas no difference was seen in the T-score quartiles of the phalangeal QUS device. These findings suggest that DXA and QUS measurements at weight-bearing skeletal sites provide useful information for assessing women with an anamnestic risk of osteoporotic bone loss. For DXA and calcaneal QUS measurements in men as well as for phalangeal QUS, however, a clinical algorithm remains to be established to understand the diagnostic implications and related therapeutic consequences of the obtained measurements.
