Well I'll am gobsmacked, that is the first time I've heard of it. I can fathom the dislocation, but cracking ribs ... I still have to wrap my mind around that.

I was thinking along the lines of what Alan said ... if you have brittle bones ... maybe, but it just sounds so odd

But can you imagine the pain you have to endure, if that happens. I personally have not broken any bones yet. But imagine your rib being cracked and your bubba kicking against it constantly and the only pain meds you can take is panadol OUCH!!!!!
