Bone strength is influenced by cortical thickness, area, mass and porosity, all of which contribute to nonvertebral fracture risk. Cortical porosity is one parameter of structural decay associated with bone fragility. This is caused by unbalanced and accelerated remodelling of Haversian units which enlarge, coalesce and fragment the cortex. Antiresorptive therapies will limit progression of cortical porosity; reducing existing porosity would be a goal for those already at incr...

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...

DMAb increases BMD and reduces bone resorption and risk of vertebral, nonvertebral and hip fractures in women with PMO. Transiliac crest bone biopsies in 47 subjects treated with DMAb for 1–3 years showed reduced bone turnover vs 45 Pbo-treated subjects, which reversed on treatment cessation. Since bone turnover reduction is sustained and fracture incidence low over 6 years’ DMAb treatment, we evaluated DMAb’s effects on tissue-level remodelling in the FREEDOM E...
