BILATERAL COMPARISON OF BONE MINERAL DENSITY IN HIP BY DEXA / 中国医师进修杂志

ABSTRACT

Objective To compare bone mineral density(BMD) at relevant measurement sites between two hips in normal subjects. Methods BMD was measured by dual energy X-ray absorptiometry(DEXA) in the two hips in 70 normal volunteer, 15 to 86 years of age(mean age 53 years). Result Highly significant correlations were found between BMD of the two hips at every measurement sites(r=0.696～0.979, P<0.001),There were small(approximately 2%～3%)but significant differences between BMD of the two hips , The right hip BMD were consistently higher than the left hip BMD at relevant measurement sites (P<0.01)； There were significant positive correlation between BMD and body weight(r=0.289～0.488, P<0.05)except Ward’s triangle. Conclusions BMDs of the two hips are highly correlated at relevant measurement sites; There are strong agreement between BMD of the two hips.
