I think there are more surgeons now that have the skills and expertise in this surgery - it's what is needed.
Have you found our Drs & PTs list sticky thread? (above the main list of TOS threads)?

I do think younger patients tend to bounce back better also.

If she might have RSD also, more surgeries could cause it to spread, so that needs to be checked into more also, as there are blocks that can be used to help prevent spread.

the search link in my siggy might be the best way to find specific info in all forums for keywords - search terms have to be more than 3 letters.

I used search terms of "blocks surgery RSD" and selected the Reflex Sympathetic Dystrophy (RSD and CRPS) forum- and it came back with results- the results link doesn't carry over when posted or I would do that..but it might be worth seeing what you find by doing it.
