Ouch - how bad is the fracture? After I broke mine it was about 6 weeks for me before I was back on the bike. However, road vibrations and bumps really sucked until about three months later. It still bothers me over two years later when I wear any type of loaded backpack or lift weights.

Make sure you do the exercises to press and hold your shoulders downward when the specialist says you're ready. Follow through with PT. The muscles in the area atrophy and you'll need to rebuild strength in the area before doing much load bearing on your arms, such as grasping handlebars. Also, make sure you wear the sling, no matter how much you hate it.

That's really too bad about the driver... The woman who hit me stopped and I was able to collect a settlement which paid for my medical expenses and a new bike. It's a long shot, but I hope you are somehow able to identify the driver at some point. Here's to a speedy recovery.
