I had my 2 week follow up yesterday for my posterior L4-L5 fusion. Prior to surgery the surgeon was going to use Allograft but I asked for Autograft. I found out yesterday that he used no graft material at all. What he did was to roughen up the bone to stimulate them to grow and used no used BMP either.
To be TOTALLY honest I was so deeply disappointed because I was hoping I would somehow fuse rapidly and be done with it all
When I asked about the grafting he explained that he didn't want to do too much to the back side since I'd already had so much done to the front. I guess I'm also feel a bit down because I was pretty sure I'd be rid of this dang back brace sooner too. Actually it's not the brace but the restrictions.
Now my thought is that with no graft material it won't fuse fast and may take longer than 6 wks. I assume 6 wks because that's the length of the restriction. Does anyone have any experience or information about fusion without graft material.
ALIF April 2011 but it turns out I broke before it barely fused.
