Mrs Figg Questions

On page 31 of SS it mentions Dudley knocking down "old Mrs. Figg, as 
she crossed private drive on her crutches." I know it's been 
established that she is a wizard, so I'm curious as to why she was on 
crutches in the first place. We've seen that in the wizarding world, 
broken bones can be faced with a single spell (One wonders when if at 
all Hogwarts students learn this, because as I've seen there are no 
healing magic classes). Why was Mrs. Figg's leg not healed then? If 
she is, as has been suggested, Harry's Secret Keeper while he's at 
the Dursley's, she could just have been keeping to her cover story 
when she went to check up on him, but did she really allow her leg to 
heal in the muggle manner to keep up a cover story? As a Secret 
Keeper, I would think one would do well to live by Moody's philosphy 
of "Contant vigilance!"...which is hard to do on a broken leg. She 
could have been faking the broken leg, but I don't think that she's 
muggle born (due to the similarities between her house and that tent 
on page 80 of GOF). So how is she to know how long it would take a 
broken leg to heal using muggle methods? - Joe
