A total of 91 female subjects aged between 41 and 78 were examined. Each of these subjects underwent densitometric analysis of bone tissue using ultrasonic apparatus at the level of the proximal phalanges of the long fingers. The same subjects then underwent single photon computerised radial bone mineral analysis. There were two aims of the study: firstly, to check the equivalence between radial bone density measurements made using single photon densitometry and using an ultrasonic technique measured at the level of the proximal phalanges of the 2nd, 3rd, 4th and 5th finger of the non-dominant hand; secondly, to correlate the characteristics of the population studied with the densitometric levels measured. Statistical analysis was performed using the graphic comparative method proposed by Altman and Bland. This showed that the difference between the measurements obtained using the two different apparatuses, namely the systematic error linked to the new measurement, was independent of the size of the error, thus confirming the validity of the ultrasonic method compared to the traditional single photon technique (non significant 't'-test). This result enables the authors to affirm legitimately that there is no significant difference between the two measuring methods.
