I can't and neither, I suspect, can you. How deep was the wingtip underground at this angle between seat 12c and the wheel?
What says spinal damage has to be in line with seat 12c and the wheel anyway?
Who says what angle you were sitting at?
You could get spinal damage anywhere in the plane with enough g, regardless of angles between seats and wheels.
And once again, an impact sufficient to damage spinal vertebrae is going to be associated with a major engineering problem. That there clearly was not one is a pretty convincing argument that this injury was not/could not have been caused by the landing you've referred to.
Why was no one else affected, even slightly?
