Abstract
-
PURPOSE: To analogize the result of the test through explaining the correlation of bone mineral density (BMD) test value between proximal femur and lumbar spine.
MATERIALS AND METHODS
It is based on 59 cases who visited the out-patient department. They were classified into two groups by age, group I (55~59 yr) and II (60~64 yr). Then we evaluated the average and the degree of correlation between the two groups and analyzed the correlation of the two sites according to the T & Z-score through the regression analysis.
RESULTS
In T-score, the correlation between L (independent variable, lumbar) and H (dependent variable, femur) indicated that L = 0.751 xH -0.195 for group I and L = 0.912 xH+0.31 for group II. In Z-score, the correlation was L = 0.647 xH -0.656 for group I and L = 0.897 xH -0.481 for group II.
CONCLUSION
It is regarded that there will be a clinical availability which can analogize the result of a part by using the result of the other part.
