PURPOSE: To have report of the relationship between bone mineral density (BMD) and subsequent fracture risk.

Materials and Methods 1-In the multicenter Study of Osteoporotic Fractures (SOF), we studied the relationship of several different BMD measures to fracture risk of multiple types in 9704 non- black women aged 65 and older. 2-we present results of the relationship of both peripheral and central BMD measures and fractures of multiple types during 10.4 and 8.5 years of follow-up,

Cont.. Osteoporosis is a disease of bones that leads to an increased risk of fracture. Osteoporosis literally means 'porous bones'. The two Greek words which make up the term osteoporosis are "osteon" which means bone and "poros" which means pore.In osteoporosis the bone mineral density (BMD) is reduced

Cont.. BMD: Bone density (or bone mineral density) is a medical term referring to the amount of matter per square centimeter of bones.Bone density (or BMD) is used in clinical medicine as an indirect indicator of osteoporosis and fracture risk

Falling and the force of impact

This image shows the bones that fracture more often in people with osteoporosis; the ones colored green are the sites of "major osteoporotic fractures": hip, spine, shoulder and forearm. osteoporotic fracture as one associated with low bone mineral density and had an increased incidence with adult age.

BMD and fracture risk Peripheral BMD was significantly associated with all types of fractures studied except facial fractures

DEXA (Dual Energy X-ray Absortiometry) imaging is used to assess risk of osteoporotic fracture (Dual Energy X-ray Absortiometry) imaging is used to assess risk of osteoporotic fracture

Result Our results show that almost all types of fractures have an increased incidence in women with low BMD. However, hip BMD is somewhat more strongly related to most of the fracture types studied than spine or peripheral BMD measures

Conclusion Finding effective prevention strategies for fractures in older women will require additional interventions beside preventions for bone loss, such as prevention of falls and other fracture risk factors
