The anteversion angle of femoral neck in 40 children, aged 18 months to 14 years (4.6 years on average), with congenital dislocation of hip was measured pre-operatively on X-ray films according to the way of Dr. Hu's method, and from the proximal femur exposed during operation. The mean value of them was 64.6 degrees and 44 degrees respectively, being statistically significant (P less than 0.01). The method of direct measurement of the anteversion angle during operation was described. The factors affecting the diversity of the measured angle value with different methods were discussed. It seems that the calculation formula used in Hu's method should somehow be corrected and a revision is put forward.
对40例年龄在18个月至14岁（平均4.6岁）的先天性髋关节脱位患儿，术前按胡氏方法在X线片上测量股骨颈前倾角，并在术中暴露的股骨近端进行测量。两者的平均值分别为64.6度和44度，差异有统计学意义（P<0.01）。描述了术中直接测量前倾角的方法。讨论了不同方法测量角度值差异的影响因素。胡氏方法中使用的计算公式似乎应作某种修正，并提出了修正意见。
