ours was only a day surgery but DD stayed overnight because of other issues.
From memory we had a check up about a week later to see how she was doing, then 6 weeks later to check on the spica and it got removed, and a brace was put on (velcro'd on and off so she could bath etc). Then 6 weeks after that she went back and didnt need the brace anymore.
After that the check ups were 6 monthly, then one a year later and now she has the all clear. We did do abit of physio but that may be able to be done closer to where you live rather then 4 hours away.
