I don't think this tells us anything more, other than confirming that stabilization surgery is not a good sign for his medium to long term playing prospects.
The follow-up tweet gives a clearer indication of the potential seriousness of the injury:

Alessi says surgery is needed when the “bones around his spinal cord are dislocated. This is a more severe injury (than a contusion.)”

“This is a much more severe situation on our hands than we thought.”

Hopefully this was all done in time to save his ability to walk.

Also given this situation, I wonder if Shazier's flipping himself over after the injury did him more damage. There have been other situations where the medical people strap a board to a guy and then flip him over so the possibly damaged spine doesn't get injured further.
