Hello from a Newbie & Moody's nose & leg

I finished GoF last night (having first begun the series on Dec. 
27th..) and was feeling bereft this morning so I am thrilled to find 
a group of adults who are as bewitched by the series as I am. Now I 
will be able to survive until the next book arrives in July....
I searched through many of the postings as well as the VFAQ and 
perhaps I missed one on the subject I wish to bring up: Moody's Nose 
and Leg - 

I can accept his "mad-eye" which though physically disturbing - 
serves a purpose. But if Harry's arm bones can be regrown and Phoenix 
tears can repair torn flesh - and for that matter - if Wormtail can 
get a replacement hand from Voldemort - why couldn't Moody get a 
replacement leg or more simply - why couldn't he get a nose job?  
Even we muggles can do that! The only theory I have is that he wished 
to wear his battle scars as a reminder to all of the evil he fought.
Any thoughts on this?
Thanks,
