How to prove TOS? What type of TOS? Cause of TOS?

[Silent_Wolf]

I fell on the ice at work three years ago. I was wearing a safty harness, as we were heading for a ladder to the roof, and a toolbelt. When I fell the metal D-Ring from the harness drove in between my shoulder blades, causing my ribs/sternum to let out a honeycomb like crunch, the belt buckle drove into my lower back and the harness rings hit my mid back. When my head hit the ground the hard hat harness broke.

When I was taken to the hospital it was misdiagnosed as a pulled muscle based on clean X-rays, no head scan. Roughly two months later I had CT results from another hospital that showd a compound concave fracture of the T3 along with two dislocated ribs.

I have been to many professionals:
-Massage therapist (loosen me up for chiro adjustments)
-Chiropractor (adjustments, popped ribs back in place, laser treatment that released muscles in back a bit, acupuncture that seemed to do nothing, ART that broke up the scar tissue, released two tendons that felt like slinkies going down the arm)
-Kinesiologist (setup an exercise plan for me)
-physiotherapist (gave me daily exercises)
-pain psychologist (taught me pain Managment techniques)
-sports specialist (6 rounds of bi-weekly injection therapy that gave me feeling back from mid arm to mid hand)

Due to the fact it was misdiagnosed for two months I was not given anything for the pain. The specialists have all expressed that they believe the inaccurate treatment in the acute stages lead to the chronic pain I now have and that the positioning I put myself in during those two months caused the tendons, neck muscles, and Apeck minor/major to shrink causing the TOS.

I have been denied by WSIB (workers comp) because there isn't enough medical evidence to prove TOS and TOS can't be connected to the "mechanism of injury".

I had an MRI and XRays what medical tests are left to do to prove TOS?
Wouldn't the released tendons and injection therapy show the TOS is neurological?
Wouldn't a direct impact to the T3 Thorasic Spine be an obvious cause of TOS?

Any suggestions would be greatly appreciated.
