My neurosurgeon, after looking at a CT-Scan, said one of the 4 screws was millimeters off its mark, (which normally doesn't matter), but in my case, breached the bone, and was likely hitting the nerve causing very painful sciatica conditions. He said the the test to check the placement "failed". Anyone ever hear of this? Is this common? Was a big mistake made that could have been avoided?
I already had surgery #2 to move the 1 screw, and the recuperation has been awful. Not even close to where I should be.
Again, I am wondering is this a problem that happens often?
