The Lumbar Gravity Line is created by first locating center of the L3 body & then droping a line downward from there, perpendicular to the bottom of the film.

This line should pass thru the anterior 1/3 of the sacral base.

If the line falls forward of sacrum there is anterior weight bearing.

If the line falls behind there then the lumbar spine has posterior weight bearing.
