He used a non-approved location and applied BMP2 to the area (which led to a pretty cool conversation between me and the surgical team. They couldn't believe that we had cracked something a complicated as BMP 2 and 7) - but the BMP usage in fusions is only approved for a 2 span fusion in the lumbar area. He used it for a 4 span fusion in the thoracic area - so I'm keeping an eye on the lawsuits that are going on right now. Some of the side effects they are describing are similar to what I'm going through, but I'm not going to jump the gun unless more definitive evidence emerges that the BMP2 usage is what caused the damage.
Right now I'm waiting on a return phone call from the surgeon to discuss everything and find out what he thinks went wrong.
