Given the personality changes seen in people who go off to fight in the military and who end up coming back fully physically intact, I think it's more likely that the personality changes here were caused by the trauma, not by the amputation.

I'm not saying the latter isn't possible, but absent evidence to the contrary, it doesn't make much sense to assume the personality changes occurred because of the amputation alone.

Also consider that amputation -- even ignoring whatever trauma precipitated it -- is its own sort of trauma. I imagine if someone came up to me, perfectly physically healthy, knocked me out, and cut off my leg, I would wake up and develop emotional trauma that would cause personality changes.
