“Slow signals” in an EMG are generally not from a nerve problem in the spine.

The non-union is another story. If this level is painful or unstable (noted by flexion/extension X-rays), then it will have to be repaired. If it is not painful and does not move, you have a stable pseudoarthrosis and do not have to do anything about it.
