  1. O-HTE bony acetabular angle, C-HTE cartilaginous acetabular angle, AAR acetabular angle ratio. Angles are given in degres and expressed as means ± SD
  2. The normal distribution of the AAR values was 1.9 ± 0.54 for normal hips in group 2 and 5.0 ± 0.84 for hips with RHD (group 1) (Fig. 3). The mean AAR values for hips presenting RHD increased by factor of 2.6 in comparison to healthy hip
