This sounds good. Too bad it always takes decades for these kinds of improvements to be implemented!

Thanks for the link.  Very interesting.  Still sounds really ominous and painful though.  I want caulking.  Perhaps I could have a port installed in both hips, and when I feel I need it, I can just squirt a little caulking in.  I'm not excited at the idea of shaving away my bone and cementing metal to it.
