Bone microarchitecture assessed by 3D high-resolution peripheral quantitative computed tomography (HR-pQCT) as predictor of fracture risk in patients with glucocorticoid-induced osteoporosis [PDF]

Journal of Orthopaedic Translation
Context: Fracture risk in patients on long-term glucocorticoid (LTGC) is only partially explained by impaired areal bone mineral density (aBMD). HR-pQCT derived bone microstructure and bone strength indices could improve fracture prediction beyond aBMD ...
