I Had/have Scoliosis. Rods Were Inserted when I Was 14., Im Now 33. I Want to Have Liposuction W Fat Grafting to my Buttucks?

Can lower back lipo be done without coming into contact w the rods? I was diagnosed with scoliosis at age 14, had surgery right away and had Harrington rods placed directly down my spine. I am now 33, I had breast silicone implants placed last year with no known problems. I now want to have lower back liposuction and BBL and was wondering if it could be done. Don't know if this is at all possible but I worry that during the suctioning that my spine could be injured or poked? Please help.
