There is a right way to fall and a wrong way. (Hint: The wrong way is leading with your nose.) Ideally, you want to minimize the force by falling on as much surface area as possible, and once you are going to fall, don't resist; just try to fall safely. Learn to fall like a martial-arts expert, so the fall won't break your spine or hip.
You can actually practice falling (with an instructor, preferably) on a padded floor. Start by falling from a low position, as in a deep squat. When you fall, don't think, react. If these tips exist somewhere in your subconscious and your muscles (muscles have memory), then you might fall correctly and minimize injury.
