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. Chronic pain and a decreased ability to carry out normal activities may occur following a broken bone.
Peripheral DXA machines were not included in the census because they can be multicenter and itinerants. Information was obtained from 232 central DXA machines throughout the Spanish territory, of which 43 were for public use, 42 in officially approved hospitals, and 147 in private institutions. The national population coverage was 5.4/million inhabitants. Most of the publicly owned DXAs are in big hospitals (>500 beds) and mainly attend requests from the hospitals themselves. Use of such equipment is mainly clinical in 87%, 88%, and 96% of public, officially approved, and private institutions, respectively.
