Femoral anteversion (torsion) was measured in 219 healthy children aged 1-15 years (boys 128, girls 91). The hips and knees were examined using a standard static-image B-mode compound scanner. The torsion in each femur was calculated. The findings show: (1) A significant negative correlation between femoral anteversion and age (r = -0.43), with only 8-22% being accounted for by age (r2 value). (2) A significant correlation between anteversion of the two femora (r = 0.77). (3) No sex difference for femoral anteversion and its asymmetry. (4) Marked degrees of femoral anteversion asymmetry (more than 10 degrees) show a pattern suggesting a relation to age, side and possibly sex. (5) Abnormal femoral anteversion asymmetry in 12 children, there being an excess of children with orthopaedic symptoms and signs in the group with femoral anteversion outside 2 S.D. (6) A relation between anteversion asymmetry and foot length/tibial length ratio. (7) No relation of femoral anteversion to social class, order in family, parental age at birth of child, birth weight and presentation. (8) A significant correlation of femoral anteversion between siblings (r = 0.66).
对219名年龄在1至15岁的健康儿童（男孩128名，女孩91名）测量了股骨前倾（扭转）。使用标准静态图像B型复合扫描仪检查髋部和膝部。计算每根股骨的扭转度。结果显示：（1）股骨前倾与年龄之间存在显著负相关（r = -0.43），年龄仅占8 - 22%（r2值）。（2）两侧股骨前倾之间存在显著相关性（r = 0.77）。（3）股骨前倾及其不对称性无性别差异。（4）明显程度的股骨前倾不对称（超过10度）呈现出一种与年龄、侧别以及可能与性别有关的模式。（5）12名儿童存在异常的股骨前倾不对称，在股骨前倾超出2个标准差的组中，有骨科症状和体征的儿童过多。（6）前倾不对称与足长/胫骨长度比值之间存在关联。（7）股骨前倾与社会阶层、家庭排行、孩子出生时父母的年龄、出生体重和分娩方式无关。（8）兄弟姐妹之间的股骨前倾存在显著相关性（r = 0.66）。
