Bones recovery

I am not confident about the english terminology, but an X-Ray confirmed today that I've acquired a bone "crack" right below knuckle four, right hand.

It has not been splinted.

TX is to keep it elevated to reduce swelling, not lift heavy things and to exercise it a lot without weights (opening and closing the fist, moving generally, etc).

When what signs occur and at what speed can workouts and training start up again?
Time expectancy?
