VER THE YEARS many definitions of osteoporosis have been 0 offered to describe variously the outcome events (fragility fractures), the process giving rise to porous bones, or the resultant diminution of bone mass. More consistency has been achieved in recent years by the development of definitions that cover the spectrum of its manifestations. from the reduced amount of bone present to some of the consequences of bone loss. A consensus development conference statement defined osteoporosis as "a disease characterized by low bonc mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk."'" The definition has survived the rigors of the most recent consensus development confcrence."' There are, however, a number of problems which need to be addressed in adapting a conceptual definition for clinical use. Some of these problems were recently discussed by an expert panel of the World Health Organization."' This paper summarizes these issues and proposes diagnostic criteria for osteoporosis for practical use.

The diagnosis of osteoporosis

Design of the Women's Health Initiative clinical trial and observational study

Summary Guidance is provided in a European setting on the assessment and treatment of postmenopausal women with or at risk from osteoporosis. Introduction The European Foundation for Osteoporosis and Bone disease (subsequently the International Osteopo- rosis Foundation) published guidelines for the diagnosis and management of osteoporosis in 1997. This manuscript updates these in a European setting. Methods The following areas are reviewed: the role of bone mineral density measurement for the diagnosis of osteoporo- sis and assessment of fracture risk; general and pharmaco- logical management of osteoporosis; monitoring of treatment; assessment of fracture risk; case finding strategies; investigation of patients; health economics of treatment. Results and conclusions A platform is provided on which specific guidelines can be developed for national use.

European guidance for the diagnosis and management of osteoporosis in postmenopausal women

Background Postmenopausal osteoporosis is a serious health problem, and additional treatments are needed. Methods We studied the effects of oral alendronate, an aminobisphosphonate, on bone mineral density and the incidence of fractures and height loss in 994 women with postmenopausal osteoporosis. The women were treated with placebo or alendronate (5 or 10 mg daily for three years, or 20 mg for two years followed by 5 mg for one year); all the women received 500 mg of calcium daily. Bone mineral density was measured by dual-energy x-ray absorptiometry. The occurrence of new vertebral fractures and the progression of vertebral deformities were determined by an analysis of digitized radiographs, and loss of height was determined by sequential height measurements. Results The women receiving alendronate had significant, progressive increases in bone mineral density at all skeletal sites, whereas those receiving placebo had decreases in bone mineral density. At three years, the mean (±SE) differences in bone...
