Jen, I don't know if this will help, yet there are some images on these pages:

GJZH, I may have read about the screw stabilization in the past; I read so much that it something become fuzzy . Sacroliliac fusion (by surgery) does seem rather scary; I'd rather take the natural route, since it's gonna happen anyway, but... to get the alignment, surgery may be the better option.

Let us know how your injection goes, and whether it seems to help you.
