I am having an alif plif fusion done at L5S1 with titanium cage. I have read much on this site about BMP especially the posts in 2009. In 2009 ERNurse stated that the trend was shifting to Autograft. So what's the currently favored choice by surgeons? Can't find many 2011 posts regarding BMP. Those that have had recent fusions, can you let me know if you had BMP and if any side effects occurred? If not BMP then please comment on autograft or allograft results. From all the reading I think I prefer my own bone (from my spine if there is enough) with maybe bone marrow from my hip. Thank you.
