Quantitative heel ultrasound in 3180 women between 45 and 75 years of age: Compliance, normal ranges and relationship to fracture history

There is growing evidence to support the use of quantitative ultrasound (QUS) to identify fracture risk in late postmenopausal women but few data are available in younger women. In order to address this issue all women between 45 and 75 years of age registered in two general practices in Bournemouth, Dorset, UK were invited to attend for heel QUS. Measurements were made in 79% of the 4018 women identified. The mean QUS results for 5-year age groups were very similar to those from reported reference ranges from North America and the north of England. The odds ratios (95% confidence limits) for self-reported fractures after 45 years per standard deviation of age-adjusted QUS parameters were: broadband ultrasound attenuation (BUA) = 1.40 (1.26-1.56), speed of sound (SOS) 1.56 (1.41-1.74) and Stiffness = 1.52 (1.37-1.68). The results suggest that QUS is associated with fracture history in early postmenopausal women.
