Document Summary
Silent disease" not manifested until fracture, spinal deformity or loss of height asymptomatic until fracture. Osteoporosis: epidemiology: over 80% of all fractures in people 50+ are caused by osteoporosis. Hundreds of thousands of canadians needlessly fracture each year because their osteoporosis goes undiagnosed and untreated: only 44% of people discharged from hospital for a hip fracture return home; of the rest, 10% go to another hospital, 27% go to rehabilitation care, and 17% go to long-term care facilities. Internal bone integrity: maintained by a remodeling" process, new bone is formed". 10% bone mass changes every year osteoblasts form bones osteoclasts dig out bone because of an imbalance in the bone remodeling process bone resorption" by osteoclasts is favoured over bone formation" by osteoblasts. Vertebral body not enough bone to take impact bone fractures quickly. Pathophysiology post menopausal - due to less estrogen age related - due to age.
