I've never hunted with anything broken, but I have gone while sick. I've had the flu and colds many many times but that wont stop me. I've with with sprained ankles(which in the Texas Hill Country, if any of you guys hunt there, is A PAIN when your feet aren't up to snuff).

My dad's gone with shingles AND a broken toe. Broke his toe the morning we got up to go to the ranch. Couldn't where boots and his tennis shoes were too tight. So he cut the toe area out of one of the sneakers so he could walk. Sucked when he stumbled through some prickley pear though!

My dad had a friend who got hog cut pretty bad and his leg was still no good by hunting season, so he rigged a pulley system to lift himself into his bow stand. Worked so well he never stopped using it for years afterwards.
