Background: Bone marrow edema (BME) is a localised bone lesion. We hypothesize that structural bone alterations increase the susceptibility to BME. Aim of this study was to analyse bone micro structure, bone mineral density (BMD) and serum fasting bone turnover marker (BTM) values in patients with BME.Methods: We compared 14 nonosteoporotic patients (43.7±19.2 years) with atraumatic BME of lower limb to 35 age-matched healthy controls (HC). HR-pQCT ...

Introduction: Effective treatment of postmenopausal osteoporosis (PMO) is frequently compromised by poor adherence to short-term (≤1-monthly) medications. Aim of this study is to investigate the effect of parenteral ibandronate (IBN) compared to denosumab in a cohort of IBN pretreated PMO patients.Methods: In a retrospective analysis, a total of 808 women were treated with quarterly 3 mg IBN injections for 27+3 months and were regularly mo...

Aging is a complex process that results in the decline of physiologic functions due to accumulation of damage in cells and tissues. Mesenchymal stem cells (MSCs) counteract this decline but their regeneration capacity decreases with age. In particular osteogenic differentiation potential of MSCs has been shown to decrease with age thereby contributing to slowed down bone formation and osteoporosis. While much is known about cellular aging of MSCs, little is known about factors...
