Osteoporosis in Argentina.
In Argentina there are approximately 150 equipments of densitometry (population 35,000,000) :more than 90% of them are DEXA axial densitometers. Most centers performing densitometry inform that the patient has osteoporosis when the T-score of either spine or proximal femur is below 2.5 SD from young normals. This has led to frequent errors in diagnosis such as treating for osteoporosis patients having primary hyperparathyroidism. Epidemiological studies of hip fractures disclosed an annual incidence of 380 fractures (women) and 100 fractures (men) per 100,000 persons above 50 years of age.
