Osteoporosis-The concept of osteoporosis

Osteoporosis is Pornmer raised in 1885, but the people's awareness of osteoporosis, with the historical development and technological progress gradually deepening. Early years is generally believed that the body shall be reduced bone osteoporosis, the United States believes that the elderly osteoporotic fractures. Until 1990, held in Denmark in the Third International Osteoporosis Symposium, as well as held in Hong Kong in 1993, the Fourth International Symposium on Osteoporosis, osteoporosis, have a clearly defined and recognized by the world : Primary osteoporosis is reduced bone mass, bone micro-structure characterized by degradation, resulting in increased bone fragility and fracture-prone as a systemic skeletal disease. October 20 each year, "International Osteoporosis Day."

On the conceptual definition of osteoporosis, understanding and awareness:

1) bone mass reduction: should include bone mineral and its matrix proportional reduction.

2) degenerative bone micro-architecture: As the absorption and formation of bone tissue due to an imbalance and other reasons, showing trabecular structure of bone destruction, thinning and fracture.

3) increased brittleness of bone, bone mechanical strength decreased risk of fracture increased, the lowering of load tolerance prone to micro-fracture or complete fracture. Can be quietly lumbar compression fracture occurs, or occurred under little external distal radius, proximal femur, and upper limb fractures.
