Estimated Frax Fracture Risk in Individuals
Frax is a tool developed to estimate the risk of fracture in individuals of both sexes and different population groups. Frax was developed by the World Health Organization from population studies of Europe, North America, Asia and Australia.
Frax's computer program is based on individual models that combine and integrate the different clinical risk factors with bone mineral density (DMO) of the femoral neck.
The risk factors contemplated are: age, sex, weight, height, the antecedent of prior fracture, the history of parents with fracture, smoking, the use of glucocorticoids, the antecedent of rheumatoid arthritis and alcohol consumption.
The algorithm calculates the possibility of fracture to 10 years (probability of hip fracture and other important fractures related to osteoporosis [vertebral fracture, forearm or shoulder]).
The Frax calculation does not say how to treat patients with osteoporosis. The treatment depends on the clinical judgment. In most countries there are clinical guides based on opinions of experts and/or health economy calculations.
