Considering that Mr. Shinkawa didn't draw Miller missing any limbs, and now Miller apparently has only one arm and one leg, I wouldn't say that official artwork has to be taken as unalterable or 100% canon. Besides, some scars don't necessarily become very noticable, and those might have healed and never scarred at all.
