I'm new to here but not to back problems. I've had a discectomy done in 2003 and a microdiscectomy laminectomy in 2004 both on L5-S1 disc. I have been feeling good until oct 2010 when I injured myself again at work. I have tried therapy, pills and cortasone injections all to no avail. I had an MRI done that showed herniations at L4-L5 and L5-S1. I ahve also had a ct scan done that revieled I have a bilateral pars defect fracture at L4. It was recomended I have a TLIF done. Another doctor recomended an axiaLIF. I just wanted to know if anyone has had the axiaLIF done, and what complications they have had or what thier outcome was. I am a volenteer firefighter and would like to be able to continue doing that after surgery along with softball, golf, and other normal activities. Will my motion be limited ar will there be comtinued pain with active recreation? Any answer would be helpful.
