Broken Leg? Get a scooter!

On my way into work this morning, I saw the best way of dealing with a broken leg. The device looks a bit like a 4 wheeled scooter with a knee-high platform. The man with the broken leg was kneeling with his broken leg on the scooter and pushing himself along the sidewalk with his good leg. No more crutches, no more sore armpits!
