I'm still at a loss as to how the kyubi chakra could recover from a giant hole in his torso, but not his arm. Probably because with the hole, he was healing/repairing damaged tissue and organs where-as with the arm, it was completely, so there was nothing to heal. Kurama has shown that it can heal wounds but never that it can regenerate entire lost limbs.

Also Kurama was chakra drained and unconcious at that point. Nothin he could do to help Naruto.
