I have recently looked at some recent imaging of my back, and it appears that my lamina was removed during a microdiscectomy at the L5-S1 level. Now, I'm not sure if this is normally a part of a microdiscectomy, but I was never told about it and it was never explained to me that it would be removed. What I was told is that a small portion of the side of my vertebra would be removed/excised in order to fix the damaged portion of the disc.
I'm not sure if the lamina even has much significance in terms of stability, pain, etc., but ever since my first back surgery I have had a lot of problems. The main things being that after my surgery I lost my achilles reflexes completely, my right ankle and most of my right foot have no feeling/sensation, and I have a distinct sharp pain just to the right of my surgical site.
And when I had to have a fusion surgery a little over a year later, my new neurosurgeon described what he saw as "a lot of scar tissue with my nerves all tangled up"...
So, anyone else had similar problems or know anything about the whole "laminectomy" thing?
