Abstract

Average life expectancy is getting longer due to medical developments and improvements in living standards. So much so that the elderly have an increased risk of developing osteoporosis. Therefore, it is important to prevent, diagnose, and treat the senile disease at an early stage through a bone density test. Bone density is measured by dual energy X-ray absorption (DXA). In this study, while using DXA, in cases when the measurements for both the lumbar and the femur could not be taken simultaneously, the correlation between both measurements were known, and the measurement of one area was used to make a clinical inference for the value of the other. Measurements were taken using Lunar Prodigy Advance (GE) for 43 participant with clinically significant fractures. Statistical calculations were produced and analysed regarding bone density. In case of T-score, lumbar spine produced a statistical result of $-2.112{\pm}1.836$ and femur neck was $-1.716{\pm}1.565$. In case of Z-score lumbar spine produced a statistical result of $-0.151{\pm}1.513$, and femur neck $-0.026{\pm}1.283$. It is indicated that the pearson correlation coefficient of T-score between lumbar spine and femur neck is high at 0.699, and the pearson correlation coefficient of Z-score is considered relatively high at 0.503. The correlation of bone density between lumbar spine and femur neck is shown to be statistically meaningful in T-score's p-value at 0.000 and Z-score's p-value at 0.001. In conclusion, it seems to have clinical usefulness that we can infer the result of one measurement through that of the other part tested, based on the knowledge of the correlation coefficients between lumbar spine and femur neck.
