Just an idea but something that she might look forward too, is getting a fabric bag or maybe even a gift bag and every monday she gets to open it and find a little gift.
Like a new coloring book, a new card game. a new story book, a blank notebook and a new pen, playdough
I would find some fun educational computer sites starfall.com, scholastic.com. etc and let her do that more than normal.
What about asking all her out of town friends and family to Mail her get well cards at different intervals. if they inculded stickers or something that would make it even better.
Find friends that can SKYPE with her video calls over the internet.
family fun.com has lots and lots of great recycled craft activites.
if you are just looking for Outings to take her on, inadditon to the others HomeDepot and lowes ect have programs for free every other Sat am or something where you can go build a simple project like a birdhouse or something check their websites
Oh and my last big Tip for entertaining the kiddos, Borrow books on CD from the library, pop it in a cd player and you are free to clean your house while they color and listen for 20 mins to an hour depending.
My kids love the Junie B Jones on CD--she is definately an example of what not to do bad manners etc so my kids get to be bad vicariously through her, even thought they can't act like that in real life. But there are lots of Disnsey books on Cd, WE love the picture books by John Lithgow that have music CD's to go with them. I'm sure your libariand could help.
good luck i hope every thign goes well
opps one more, even though she mightnot be able to get a cast wet or something, you could make her a little water table from a plastic basin, My kids at that age loved filling muffin tins with water usign those medicine droppers you get or a big turkey baster if you have one.
