Abstract
To examine the relation of hand preference to bilateral femoral bone mineral density (BMD), the right and left total and regional (neck, trochanter, intertrochanteric, and Ward's triangle) proximal femur BMDs (g/cm2) were measured using dual-energy X-ray absorbtiometry (DEXA) in 32 right- and 26 left-handed university students. The mean total BMD of the total right-handers and the mean trochanteric BMD of the right- handed males were greater in the left femur than the right femur. Contrarily, the total left-handers had higher mean intertrochanteric BMD in the right side than in the left side. There were negative correlations between R-L BMD differences and Geschwind scores of total, male, and female subjects. The results suggest that femur-BMD may be related to hand preference.
