- The use of FRAX, particularly in the absence of BMD, has been the subject of some debate and is the focus of this review. The clinical risk factors used in FRAX have high validity as judged from an evidence-based assessment and identify a risk that is responsive to pharmaceutical intervention. Moreover, treatment effects, with the possible exception of alendronate, are not dependent on baseline BMD and strongly suggest that FRAX identifies high-risk patients who respond to pharmaceutical interventions. In addition, the selection of high-risk individuals with FRAX, without knowledge of BMD, preferentially selects for low BMD. The prediction of fractures with the use of clinical risk factors alone in FRAX is comparable to the use of BMD alone to predict fractures and is suitable, therefore, in the many countries where DXA facilities are sparse. In countries where access to BMD is greater, FRAX can be used without BMD in the majority of cases and BMD tests reserved for those close to a probability-based intervention threshold. Whereas the efficacy for agents to reduce fracture risk has not been tested prospectively in randomized controlled trials in patients selected on the basis of FRAX probabilities, there is compelling evidence that FRAX with or without the use of BMD provides a well-validated instrument for targeting patients most likely to benefit from an intervention.

- The aim of the study was to determine the number of hip fractures within defined countries for 2010 and the proportion attributable to osteoporosis. The number of incident hip fractures in one year in countries for which data were available was calculated from the population demography in 2010 and the age- and sex-specific risk of hip fracture. The number of hip fractures attributed to osteoporosis was computed as the number of hip fractures that would be saved assuming that no individual could have a femoral neck T-score of less than -2.5 SD (i.e., the lowest attainable T-score was that at the threshold of osteoporosis (=-2.5 SD). The total number of new hip fractures for 58 countries was 2.32 million (741,005 in men and 1,578,809 in women) with a female-to-male ratio of 2.13. Of these 1,159,727 (50 %) would be saved if bone mineral density in individuals with osteoporosis were set at a T-score of -2.5 SD. The majority (83 %) of these "prevented" hip fractures were found in men and women at the age of 70 years or more. The 58 countries assessed accounted for 83.5 % of the world population aged 50 years or more. Extrapolation to the world population using age- and sex-specific rates gave an estimated number of hip fractures of approximately 2.7 million in 2010, of which 1,364,717 were preventable with the avoidance of osteoporosis (264,162 in men and 1,100,555 in women). We conclude that osteoporosis accounts for approximately half of all hip fractures. Strategies to prevent osteoporosis could save up to 50 % of all hip fractures.
