Hello to all of my fellow spineies out there. I have a few questions for everyone about some things I just noticed on my pre-op insurance report. I was wondering if anyone could tell me what the following things mean. 1)Laminotomy is the first one, 2)Release of spinal cord is the second and the last thing is what is the difference between a spinal bone autograft and a spinal bone allograft. I found info on this stuff but do not understand it. Any and all help would be greatly appreciated. I hope that everyone is having a pain free day!
