Reference curve of bone ultrasound measurements in proximal phalanges in normal Spanish women.

There are clear discrepancies in how the different measurements of phalangeal bone ultrasound, such as the amplitude-dependent speed of bone ultrasound (Ad-SoS), correlate with age, given their dependence on gonadal status and other anthropometric variables. In order to contribute to clarifying these discrepancies, we evaluated the phalangeal Ad-SoS in healthy women-295 postmenopausal, 59 perimenopausal, and 270 premenopausal. Phalanges (II-V) of the nondominant hand were measured and the mean Ad-SoS was computed.
