Sorry to butt in but I think yes she had the Fenrir scaring but probably not permanent damage from the fall. Magic can fix some pretty yucky non-magical injuries.

Also Remus having scars is Fanon not Canon. Never once does it mention Remus's scars because at least in canon Harry never sees Remus with his clothes off (only Sirius does). He has lines on his young face and grey hair are the tips his body has been stressed more than the average. However we can safely assume because he used to have to bite and scratch himself he does indeed have scars. *shuts up now*
