[The frequency of osteoporosis diagnosis depending on the site and method of bone examination].
The aim of the study has been to evaluate how often osteoporosis is diagnosed in DEXA examination of the spinal column and proximal epiphysis of the femoral bone as well as in ultrasonography of the heel in a population group. The study comprised 536 post-menopausal women aged 54.36+/-10.91 years. A fracture in history was reported by 158 patients, including 57 fractures characteristic of osteoporosis (spinal column, forearm, proximal epiphysis of the femoral bone). Osteoporosis was diagnosed in 0.4% patients in the greater trochanter, in 1.5% in the neck of femur, in 7.8% in the Ward triangle, in 12.8% in the L1-L4 segment of the spine, and in as many as 36.2% in the calcaneal bone. Here, no abnormalities were found only in 14.2% of the patients. The frequency of positive osteoporosis diagnosis did not differ significantly between the groups with and without fractures in history. There was a correlation found between measurements results of the spine and the Ward triangle, and between the neck of femur and the greater trochanter. In the remaining DEXA measurements, the statistics values were a little beyond the critical ones. On the other hand, ultrasonographic diagnosis of osteoporosis in the heel did not correlate absolutely with those of DEXA. T-score in each measurement correlated with each other at r from 0.453 to 0.905, with the highest values when in DEXA. Comparing T-score in sonography of the heel with those of DEXA suggests that they have been overrated by one standard deviation. In conclusion, the frequency of osteoporosis diagnosis has been found to differ significantly depending on the method and site of measurement. The measurement discrepancy in various sites is substantial despite a high correlation between them. The paper's results suggest that it is necessary to work out other diagnostic criteria for the ultrasonographic examination of the heel.
