Bob,
'how longs' are always hard to answer - depends on the exact procedure and how well you heal. If you search on reconstruction, you should be able to find some relatively recent posts on this topic. My husband did not have this time of treatment and I am not well up on it.

If the Czech doctors are suggesting the UK for reconstruction treatment - do you have any family resources to draw on where this would be a possibility? I don't know about the UK, but it is possible to negotiate prices with the hospital in the States if one is uninsured.
