Presumably Naruto nature-transformed them into Rasenshuriken (using whatever guides the TSB's to make them homing), and upon exploding this core never truly got damaged (as i would assume the TSB can nullify his own jutsu).

I don't know if it's a satisfying answer, many aspects of the TSB were never made clear (like why they can be permanently destroyed at all).
