A consecutive sample of 411 hip roentgenograms in 215 patients with cerebral palsy was evaluated. Femoral anteversion and neck-shaft angles were measured and compared with hip stability indexes to determine which of the two angles is more important in hip instability. The correlation coefficients were higher and statistically significant for femoral anteversion and lower and statistically nonsignificant for neck-shaft angles. These findings suggest that increased femoral anteversion has greater correlation than increased coxa valga with hip instability in cerebral palsy patients and therefore should be addressed primarily when surgically treating these hips.
对215例脑瘫患者的411张髋部X线片进行了连续抽样评估。测量了股骨前倾角和颈干角，并与髋关节稳定性指标进行比较，以确定这两个角度中哪一个在髋关节不稳定中更重要。股骨前倾角的相关系数更高且具有统计学意义，而颈干角的相关系数更低且无统计学意义。这些发现表明，在脑瘫患者中，股骨前倾角增加比髋外翻增加与髋关节不稳定的相关性更大，因此在手术治疗这些髋关节时应首先考虑解决股骨前倾角问题。
