Abstract
1.Osteoporosis does not cause pain until bone fracture occurs. Most of the pains complained by osteoporosis patients are caused by osteoarthritis and factors originating in the muscles. 2. It is known that administration of bisphosphonate, for osteoporosis, can improve pains caused by osteoarthritis. This report shows the results of research into pain reduction effected by administration of bisphosphonate. 3. Fractures of adjacent vertebra in the spine and the contralateral proximal aspect of the femur often occur after treatment of one's fractures. These are caused by the progressive weakness and decline of muscle strength during rest and immobilization for treatment of fractures. 4. In addition to these results, recent information about relationship of osteoporosis and osteoarthritis are outlined in this paper.
