T-Pelvis _ IMG_0830_28_29_31_33_34_35_36_37_38_39

This image of the pelvis is based on the recognition that the pelvic girdle can  be described modelled as an octet truss.  This means that the three joints in a pelvis; or pubic ramus, and the two sacroilliac  joints are hubs with six axes along which the force vectors are distributed along.
