FYI, my dad made it through his surgery on Monday in one piece. Unfortunately, I believe that he is now forced to wear something like this for the next 6 weeks.
At least, that's what I picture when my mom described the healing process to me.
The upside is that he can't wander too far from the house because of those pneumatic tubes in the back. Get 5 feet from the compressor and you'll fall right on your face!
