  1. †Wilcoxon signed rank test
  2. aThe values are given as the mean and the standard deviation
  3. bThese values were calculated by subtracting the values of the operated hips from the values of the contralateral hips
  4. cThese values were calculated by subtracting the values of the contralateral hips from the values of the operated hips
  5. dTwo hips which underwent pelvic osteotomy concurrent with hemi-epiphysiodesis were excluded
