- 3% in black women
prevalence of osteoporosis worldwide
8.9 million fractures annually
fracture every 3 seconds

what areas are measure in a DXA scan
radius
lumbar spine
greater trochanter
how much is fracture risk increased with a drop of 1 SD in BMD
2.6%
how much is fracture risk increased with a drop of 2.5 SDs in BMD
10%
not linear
most common fractures
- distal forearm
- hip
- spine
fracture risk factors
- fall risk
- BMD
- architecture and geometry of bones
screening of BMD
start @ 65
every 2 years get a DXA
every year if on osteoporosis therapy
can start earlier with justification
risk factors for osteoporosis in men
hypogonadism
alcoholism
glucocorticoid use
