Cathy do you know more? Why do they want to fuse her. What is her underlying pathology?

I don't know about carbon in fusions. I had titanium. they dont use banked bone for lumbar fusions---they use bone taken from laminectomies, if you have one, then some bone from the hip (there area couple of techniques for this, and one seemed less painful to me--one using a trochar to scape inside the bone. I don't think anyone uses banked bonefor this. then they also use BMP to enhance the chance of success.

What's ailing her?
