Well, the meaning isn't "broken ankle", the meaning is a reduction of your personal resources, which probably in your case can be set off by injuries (it can for many people). All that knowing the meaning in advance would have enabled you to do is take it on the chin, accept it in good spirits. If the card had come up as a warning to me, I would simply have reduced my spending and been a bit careful with money, and perhaps chose not to lend people stuff.
Now, cards like the Eight Wands which is usually associated with haste, may warn you to slow down if there is a potential of injury through speed, or the Chariot may occasionally warn of the risk of injury because of vehicles or uncontrolled energy (the "horses" not under the Charioteer's control).
There is no one card that says "broken ankle". In my opinion the deck did the right thing by you - perhaps a three-card spread as a daily would have given you more information.
If you are afraid that by predicting something bad the Tarot somehow "made it happen", you'd be totally wrong, it was instead shouting a warning at you so that you could take evasive action. Okay, so in that particular instance it wasn't shouting in the same language you were listening in - this is where spending a *lot* of time pulling cards and relating them to your life over time so as to get to know your own deck's symbolic language will come in handy. Exactly hte opposite of what you say you are doing. If you want to be more accurate, spend a lot *more* time with your deck, not less, and find out exactly what cards you draw on days when all sorts of stuff happens. No card will exactly describe an event as you seem to think they should, but after a while you'll pick up on the energies and *types* of events they are talking about, which will help yourself prepare for your day more appropriately.
Doing as you;re suggesting and *not* pulling cards in order to learn, won't help you learn what the cards you are not pulling are trying to tell you.
