I was in a accident at work a piece of machinery struck me in the back I had some numbness and slight pain and when I got to the ER the nurse put me in a wheelchair and took me over a large bump. when we went over the bump I felt horrible pain I almost passsed out. I was diagnosed with a L1 burst fracture and the Surgeon told me large bone fragment went into my spinal canal. Im now a paraplegic. Should I had been placed in a wheelchair? and could the bump she took me over caused my Paraplegia because of the unstable injury?

Summarized question: What could cause paraplegia?
