The way I read that still isn’t promising.
“Well, it seems the infection has gone away and the bone is growing properly, so now MM can START doing physical therapy and rehab on the arm.”
In other words, at least two more months before they even let him look at a motorcycle of any kind.
I had my neck surgery with bone implants in mid November. Three months later, a couple days ago, my surgeon cleared me to resume any exercise I wanted, moderated by pain. Up to now it's been only very light weight exercise, probably lost 4-5 pounds of muscle.
I was hitting 25 pushups, now I'm hitting two. Which is better than two weeks ago. I figure in a couple more months I'll be closer to 15.
What I've heard is that it will probably be a year to full return.
