this is a xsection cat scan of my L1- the oval opening you see is where your spinal cord passes through, it should be a nice clean opening around the edges, note the bone that has been forced into the opening, apparently I came close to becoming a paraplegic.

among other things I have a fucked front end, bent fork tube.
again this is my L1 (arrow) but now a side view, you can see how it has been compressed and fractured in comparison to the others.
