I had a L5S1 Fusion Sept 2010 and have had insufficient bone growth. 1st surgeon want to do an ALIF, but will not address my continued leg pain. 2nd opinion wants to do a PLIF again, but harvest bone from my hip this time in hopes that my spine will fuse. Is there more of a risk with a 2nd surgery? Anyone know what the recovery time would be the 2nd time around? Thanks for any help you can give.
