Its broken in the thick part at the very bottom.Lateral malleolus.
Some sort of walking boot thing. Still haven't gotten an appointment with my orthopedist.Depending on the exact level of your fracture, you may be fine with an immobilizing cast or you may need some small bits of incredibly expensive metal to hold things together.
Good luck!
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
