Abstract

Broadband ultrasonic attenuation (BUA) is a relatively new technique for tie measurement bone mineral content (BMC) in the os calcis (Langton et al., 1984). This is a site of mainly trabecular bone and it has been suggested that BUA values reflect bone structure as well is mineral density (Palmer and Langton. 1987). Recent clinical studies (Baran et al., 1988) indicated the high diagnostic sensitivity of technique in both spine and hip fracture patients. It has the additional advantages of being cheaper than other methods of BMC measurement and not using ionising radiation.
