Areal bone mineral density (aBMD) of the PA spine and proximal femur remained the gold standard for WHO classification of osteoporosis, fracture prediction and patient monitoring. Unfortunately, with age it is not infrequent to observe the presence of degenerative disease such as spinal osteoarthritis which would have a positive artifactual impact on aBMD which could lead to an erroneous interpretation. In a previous study it has been demonstrated that apparently such artifact...

BMD alone is not sufficient to predict the fracture risk for an individual. Others parameters, such as microarchitecture play a key role in bone fragility. Several cross-sectional studies have shown the ability of TBS to discriminate fractured from healthy subjects in European populations. The aim of our study is to assess the ability of TBS, evaluated at the lumbar spine, to discriminate subjects with and without fracture in a large white US population....

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in men of various ages.Materials and methods: 300 men aged 40–87 years (mean age – 60.5±0.6 years; mean height – 1.61±0.003 m; mean weight – 84.1±0.9 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=52), 50–59 years (n=90), ...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in women of various ages.Materials and methods: 494 women aged 41–89 years (mean age, 63.6±0.4 years; mean height, 1.61±0.003 m; and mean weight, 74.0±0.6 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=35), 50–59 years (n=130), 60–6...

The aim of the study is to compare the performance of FRAX vs TBS adjusted FRAX using Leslie B et al.1 method to better identify women at high fracture risk. The OsteoLaus cohort (1500 women 50–80 years living in Lausanne, CH) started in 2010. CRF for OP, FRAX, spine and hip BMD, VFA by DXA and TBS were recorded. Sensitivity and specificity in regard to vertebral fracture grade 2 and 3 has been calculated. Net reclassification improvement (NRI) had als...

Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...

Background: The relation between sex hormone-binding globulin (SHBG) and vertebral fracture (VFx) is unclear.Aim: To examine whether SHBG is associated with bone mineral density at lumbar spine (LS-BMD), trabecular bone score (TBS) and prevalent VFx.Methods: Data of 6224 men and women participants in the third visit of the first cohort (I-3) and the first visit of the second cohort (II-1) of a prospective population based cohort, w...

Background: Fracture risk is increased in Type 2 diabetes (T2D) individuals. Bone mineral density (BMD) is inversely associated with fracture risk but paradoxically high in T2D individuals. Trabecular bone score (TBS) reflects bone microarchitecture and predicts fracture risk.Objective: We aimed to compare mean lumbar spine TBS (LS-TBS) and lumbar spine BMD (LS-BMD) values, across individuals with and without i) vertebral fracture (VFx), ii) T2D; and iii...
