Update II - 8pm

CSU just called, Rukh came through surgery very well -- he's groggy but comfortable.

They did the amputation all the way up to the hip socket, removing the entire femur and all the musculature associated with the leg. I assume that is because it's easier for them to balance without any structure on that side, and to remove as much weight from his rear as possible.

Here's hoping that he can get up and move around tomorrow, so he can come home!
