In standing-Intact rigid bony pelvis transmits body weight through acetabulum of hip bone to lower limb
In sitting- body weight transmitted to ischial tuberosities and legs are free to rest.
What is anatomical positioning of the femur.
**What is the femoral angle of inclination
Abnormally decreased angle Usually less than 120º –Coxa Vara
Normal angle b/w Neck Shaft of Femur is 125º (Range 125-135º degrees)
Abnormally increased angle beyond >140º is-Coxa Valga
