I had this exact same kind of fracture. I had 3 different casts on for 18 and a half weeks. The first 12 i had 2 different full leg casts and then the last 6 and a half i had a cast up to my knee. I got the cast on on June 20th, and got it off on October 28th, so after i got it off i wasn't aloud to play sports until the end of march
