Z said the man who cut his arm off is now a shichibukai. Its definitely not Bonney. Even if it wasn't canon, Z is still a real character Oda made and his movie is still one HE wrote.

My theory is that its this "Jack" character who was one of the people watching the Caesar fight when they were showing the different brokers. But right or wrong, I'm pretty sure Bonney was shown to be free and with her crew on some winter island.
