Just saw this on reddit and decided to make an account and post this here. I mean...that seems like it could be helpful, right? If you could just break the bone, separate it out an inch or two, and place a 2-inch implant in between the broken pieces--the thing is basically bone--it creates it's own red blood cells and marrow and everything.

Thoughts?
