Thanks for your reply. My doctor put the rods in this time to help support my spine. The way he described it I would think that yes you need the rods to help relieve some pressure.
The rods help maintain everything. He thinks it was due to doing both procedures from the back I didn't want a 360.
I find out Tues. if I have to redo it all.
Good Luck to you and let me know what happens.
You said your fusion failed before because the bone didn't grow, do you smoke or did you take any anti-inflamatory medication after surgery?
