Osteoporosis is a disease where decreased bone strength increases the risk of a broken bone. It is the most common reason for a broken bone among people who are old.Bones that commonly break include the back bones, the bones of the forearm, and the hip.Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously.
Direct costs of osteoporosis were considered.In 2003, 7.8 million Germans (6.5 million women) were affected by osteoporosis. Of them, 4.3% experienced at least one clinical fracture. Only 21.7% were treated with an anti-osteoporosis drug. The total direct costs attributable to osteoporosis amounted to euros 5.4 billion.
