Abstract

BACKGROUND: The purpose of this study is to investigate the correlations between distal radius BMD and other skeletal sites (L2-L4, Femoral neck, Ward's triangle, Trochanter) BMDs, and to find aut the usefulness of DTX-200.
METHODS
The authors surveyed the subjects of 76 perimenopausal women who had visited Kyunghee Medical Center and measured their bone mineral densities (BMDs) from February, 1997 to July, 1997. Measurements were done for distal radius, ultradistal-8mm radius BMD using DTX-200 (OSTEOMETER, Denmark), and other skeletal sites (L2-L4, Femoral neck, Wards triangle, Trochanter) BMDs using EXPERT (Lunar, USA). Using SPSS for windows, the correlation coefficients of the BMDs of both instruments were calculated.
RESULTS
The total number of subjects were 76 (average age, 54.8 years, range 32~78years). Among them, 67 were postmenopausal women. The BMD measurements of various skeletal sites were as follows : distal radius, 0.41+/-0.07(g/cm2), ultradistal 8mm radius 0.34+/-0.07 (g/cm2), femoral neck 0.82+/-0.18 (g/cm2), trochanter 0.72+/-0.17 (g/cm2), Ward's triangle 0.59+/-0.22 (g/cm2), L2-L4 0.98+/-0.16(g/cm2). The correlations of BMDs between distal radius and femoral neck, trochanter, Ward's triangle, and L2-L4 were 0.44, 0.35, 0.47, and 0.63, respectively. The correlations of BMDs between ultradistal-8mm radius and femoral neck, trochanter, Ward's triangle, and L2-L4 were 0.64, 0.34, 0.41, and 0.69 respectively.
CONCLUSION
The correlations of BMDs between distal radius and those of femoral neck, trochanter, Ward's triangle, L2-L4 were moderately high.
