Abstract
PURPOSE OF THIS REVIEW:
The goal of the review is to provide an updated understanding of the pathophysiology of glucocorticoid-induced osteoporosis and treatment recommendations.

RECENT FINDINGS:
Glucocorticoids reduce osteoblast and osteocyte lifespan and activity and reduce the vascularity of the bone that together may explain the greater reductions in bone strength than those of bone mass. Treatments with parathyroid hormone fragments appear to reverse glucocorticoid-induced bone loss and fracture risk partially through maintaining bone vascularity and bone strength. This review identifies how glucocorticoid anti-osteogenic and vascular effects together may reduce bone strength. It also provides guidance to clinicians on rationale treatment for glucocorticoid-induced osteoporosis.
