To get more long term results a search of member's user names that had surgeries might be a good idea, they may not be posting any more or reading here but you could send a PM and ask about an update on long term results.

FYI-
There are some that will have adhesions /scar tissue come back or regrow in the surgical areas or nearby locations. This may occur at any time but usually from past postings in the 6 + months or longer time frame.
Some bodies just happen to create more of this than others, and no telling who might have this issue.

I'm sure surgical knowledge, imaging & technique have improved over the years, but it is still a roll of the dice, on how anyone will recover & how well they will recover.

Hank Blalock a baseball player (former TX Ranger player} had TOS surgery, supposedly he recovered well but his ball playing career never recovered to the high that it had been. Lots of minor injuries plagued him, w/hands/arms /shoulders - I think it was residual chronic TOS.
He never posted here, but I checked on his bio once a year out of curiosity to see how he was doing.

One of the Hanson singers had TOS surgery I think.
