RESUMO

Osteoporosis is a disease which affects the bone tissue reducing its resistance that is determined by its density, architecture and speed of remodeling. Currently, the pattern method used for its diagnosis and monitoring is the bone densitometry which makes use of ionizing radiation and because of its high costs, it is not available to the majority of the low-income population. It also has the inconvenience of neither assessing adequately the bone mass nor its resistance. Several studies have been published discussing the use of complementary or alternative techniques to make this evaluation more reliable. One of these techniques is the bone ultra-sonometry of the calcaneus which is based on the analysis of the ultrasound propagation thought the bone translating information about its quality and therefore predicting mainly the fracture risk in the femoral collum this method do not use ionizing radiation, it is easy to apply and has low costs. Nowadays, it is used for populational screening of individuals who are candidates for bone densitometry. As its results have a better correlation with this method in the old individual and in the assessment of the femoral neck, its utilization its proposed to evaluate low-income patients registered at the public health, most of them suffering from concomitant diseases, screening them in the order to be submitted to preventive programs of femoral fractures, the consequence of increased morbity and mortality related to osteoporosis. As a method, a group of 757 old women was submitted to the evaluation by the bone ultra-sonometry of the calcaneus. 71% or the women were considered with increased fracture risk (24% with osteoporosis and 47% with osteopenia according to the WHO criteria for densitometry) and 29% were normal, important data because of the high number of individuals at risk. Other parameters were also analyzed in terms of a questionnaire answered by the evaluated women showing the concomitance of diseases besides other information. The obtained data are not coincident with those from the literature that observes old individuals who were randomly chosen within the population in general. Such a fact is related to the criterion used for the choice of the studied universe constituted by patients and not simply by individuals who were already registered at the health treatment service. For these reasons, it was concluded that the method in question is valuable to screen low-income old women with the facture risk increased by the reduction of the bone resistance and conduct them to preventive programs of femoral fractures.
