title: Handedness and bilateral femoral bone densities in men and women.
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.
