The objective of this study was to compare the proportion of patients at high fracture risk according to FRAX® and FRAX® adjusted on TBS in patients hospitalized for a non vertebral fractures. Patients were selected from a Fracture Liaison Service FLS): clinical risk factors, bone mineral density (BMD) and TBS were assessed at the time of the fracture. Without considering the current fracture, we calculated FRAX® and FRAX® adjusted on TBS (TBS-FRAX®), and compared the proportion of patients with a high risk for major osteoporotic fracture (MOF)>20% according to FRAX® and TBS-FRAX®, and the proportion of subjects who should be treated according to current guidelines. Four hundred and thirteen patients were included for a non vertebral fracture (84.5% women, mean age of 73.9±11.7years), Two hundred and eight patients (50.4%) had osteoporosis (T≤-2.5 at least one site) and the mean value of TBS was 1.206 (±0.111). The proportion of patients with a risk of MOF≥20% before the fracture was similar with FRAX® and TBS-FRAX® (24.7% vs 25.4%). The proportion of patients identified with a risk of MOF above the threshold value of therapeutic intervention was higher using TBS-FRAX® than FRAX® for the age categories of 60-70years (38.3% vs 30.9%, p=0.01) and 70-80years (31.2% vs. 26.6%, p=0.04). This study showed that the proportion of patients at high risk of fracture is similar using FRAX® and FRAX® adjusted on TBS in patients hospitalized for a non vertebral fracture in a FLS.
