Ive been scrabling around with Fallout 3 trying to fix that big left arm problem (pipboy one ) .Still nothing .Reinstalled skeleton ,tryed vanilla new game nothing works .Can some of you send me your Falloutprefs ini so i can see whats missing .Its not happening in fallout NV .Only in Fo3 .Sope of you sayd that dirvers might cause this but im not sure anymore .
Help if you can or if you have the same problem .Tryed to find some possible fixes but nothing .

I'm not willing to send you my FalloutPrefs.ini as it has custom settings specific to my machine.

Although, if you happen to have a pic of the issue then maybe I can see what may be causing the issue.

Umm im currently reinstalling Fallout 3 so ...this will take a while .Hmm you can find a pic on this thread that was posted on nexus i have the same problem http://forums.nexusmods.com/index.php?/topic/152583-female-huge-mutated-left-hand/.The first pic you see .Im gonna try fixing it meanwhille.
