我们评估被动髋关节运动范围是否可靠预测异常股骨前倾。我们测量了1140名8 - 9岁儿童双髋被动内侧和外侧旋转伸展，将儿童分为3组：第一组：外侧和内侧旋转差异小于10度；第二组：内侧旋转大于外侧旋转10度以上；第三组：外侧旋转大于内侧10度以上。第一组占90%，第二组占8%，第三组占2%。第一组57例、第二组67例、第三组24例患儿采用双平面x线摄影测量股骨颈前倾角，3组平均前倾角分别为24度、36度和14度，预测前倾角异常高（高于平均值+2SD），内侧和外侧旋转差值必须大于45度。而当侧旋比内侧旋高至少50度时，可以预测异常低的前倾角（低于平均-2SD）。
We assessed whether the range of passive hip motion is reliable for predicting abnormal femoral anteversion. We measured the passive medial and lateral rotation in extension in both hips of 1,140 children between 8 and 9 years of age, The children were divided into 3 groups: group 1: difference between lateral and medial rotation less than 10 degrees; group 2: medial rotation more than 10 degrees greater than the lateral; group 3: lateral rotation more than 10 degrees greater than the medial. Group 1 comprised 90% of the children, whereas 8% belonged to group 2 and 2% to group 3.The angle of femoral neck anteversion was measured in 57 children from the first group, in 67 from the second and in 24 children from the third group, using biplane radiography, The mean anteversion angles in the 3 groups were 24 degrees, 36 degrees and 14 degrees, respectively, To predict an abnormally high anteversion angle (above mean +2SD), the difference between medial and lateral rotation must be 45 degrees or more, whereas an abnormally low anteversion angle (lower than mean -2SD) could be predicted when the lateral rotation was at least 50 degrees higher than the medial rotation.
