How would you repot?

[OhioBob]

I have a Dendrobium potted in a clay pot. Two days ago the dog knocked it over and broke the pot. It is still sitting mostly in a pot shape, the broken shards are still sitting around the media so it isn't loose. Most of one side is shattered while a quarter is still solid, Not sure about the bottom but the plant is still upright and the media is in the pot.
So I am thinking of either removing all the part shards and repotting by using new media or should remove the smallest shards and repot by putting what is left of the pot into another pot and filling with more media as needed? The media is a mix of lava rock and bark (70-30). The bark is still good. too late at night to get a picture but I'll try tomorrow.
