Will having had a spinal fusion keep me from having the SculpSure or Cool Sculpting done?

There would be no problem having SculpSure or CoolSculpting done after a spinal fusion surgery.  Neither procedure should affect the spine.  

Yes. It is safe to get SculpSure if you have a spinal fusion. You just want to keep the panels away from any scar tissue and not place them over any internal hardware. Best of luck.
