thank you for your comments Mr XLA, I am neither consultant/doctor/radiologist, however when someone posts on here with a rather complicated question in the first place, I try to give a somewhat "simple" answer if there ever is such a thing?
I was merely mentioning an avenue with the reports that maybe scorpious hadn't thought of going down rather than pinning all hopes/blame/problems on the orthopaedic surgeons and I did actually make a slight reference that we are a team because they come down for our opinion!!
I think you underestimate imaging proceedures these days i'm sure scorpious's images were looked at with 3D reconstructions/ bony windows/sequences and with intravenous contrast i'm sure they didn't miss a thing. Radiologists training is very similar with a vast array of imaging they have to do before becoming qualified, it's not just looking at x-rays. Hope you get sorted Scorpious, a bad back is miserable.
