I found an online orthopedic textbook with a chapter about my injury. It does a nice job explaining the physics of these injuries and typical patient outcomes.
I think it was written before snowboarding was invented. The chapter says the most common causes of my injury are motor vehicle accidents and falls from 10 feet or higher.
Like I'm stupid enough to fall from a height and break my leg!
The chapter describes different techniques for fixing the fracture. I had the external fixation with delayed internal fixation.
I should be able to dunk in a few months.
