Highlight:

The identification of patients at risk for fragility fractures who may benefit from osteoporosis treatments is a challenge to clinicians. With this prospective observational study, the authors investigated the effectiveness of the T-score values provided by Radiofrequency Echographic Multi-Spectrometry (REMS) in the identification of patients at risk for incident osteoporotic fractures, comparing the performance of REMS with the Dual-energy X-ray Absorptiometry (DXA) one in a 5-years follow-up.

The studied population were over 1500 women from 30 to 90 years old who underwent REMS and DXA scans at femoral and vertebral sites. Among the findings of this study, a high agreement between REMS- and DXA-measured bone mineral density (BMD) values was observed. As concerning fragility fractures, a relationship between lower T-score values and higher fracture rate was observed, as expected.

Considering the reference T-score threshold value of −2.5 to distinguish between osteoporotic and non-osteoporotic patients, REMS showed higher sensitivity than DXA at the vertebral site in the identification of incident fragility fracture (65.1% versus 57.7%, respectively), whereas the performance were comparable between techniques for the femoral site. REMS T-score resulted an effective predictor of the occurrence of incident fragility fractures, representing a valuable approach to enhance osteoporosis diagnosis in clinical routine.
