So, during the period of suspension the hip bone be- 

 comes more upright ; but as we pointed out above, these 

 variations of slope are not the result of a movement 

 proper to the hip bone. They come from the lumbar 

 arch, which after bending straightens out again when 

 the period of support begins. 



The femur becomes more sloping and the coxo-femoral 

 angle closes. 



The tibia straightens up, and the femoro-tibia angle 

 opens at the end of the period.
