Osteoporosis

Skeletal disease of low bone density and microarchitectural deterioration → fragility fractures. Driven by estrogen deficiency and osteoclast-osteoblast uncoupling; bisphosphonates, denosumab (RANKL inhibitor), and romosozumab (anti-sclerostin) reduce fracture risk.

Also known as: osteopenia, metabolic bone disease, fragility fracture, postmenopausal osteoporosis, glucocorticoid-induced osteoporosis, secondary osteoporosis
