к сожалению кость не срослась и мне надо ходить еще в гипсе и на костылях еще 2 недели поэтому ехать на встречу я не могу
Unfortunately, the bone hasn't healed yet and I'll have to walk with the cast on and use crutches for another two weeks, so I can't come to the meeting.

+Aleh: The only thing that could make this translation better would be to use GOING TO instead of WILL. The fact is that this is a concrete fact - a plan, so WILL is kind of weak here. "... I'm going to have to WEAR a cast and USE crutches..." Good work!
