Please help me with my spine condition?

Help, it would be nice to know where your slippage was located. If it is at the same level there is a good chance that you might have to undergo a fusion in the future. The reason for this is that you are potentially risking damage to the spinal cord. Talk to a neurosurgeon about this. Since you are still in your growth years I think that they will try to hold off until you stop growing.
