I have researched Sacroiliitis and have all the symptoms for a new procedure called I-fuse. I have had every procedure for back pain including epidurals, physical therapy, water aerobics, acupuncture, X-Stop inserted(Lumbar 4/5), X-Stop removed, Rhysotomy and finally Spinal fusion (Lumbar 2 thru 5). Original trauma was a 1963 Auto Accident where both femurs were crushed. The Sacroiliac/I-Fuse is not yet covered by insurance but, has a medical code (CPT0334T). Do you know about this procedure? Thanks for your help.
