I agree with curious, mustafa. Fusion is the only real answer. You can do different physical therapies to help with the pain, but if the vertebra are slipped, they need to be stabilized.

To answer the original thread question, I've had a fusion of L4/5 L5-S1. Solid as a rock. Worked as a medic about 6 months out from surgery. It has now been about 5 years. (wow! that long, already?) No other lumbar- level damage. I actually had l5-S1 blow because of the strain of not having l4/l5 fused. I hope everything turned out ok...
