With a normal break, you can ski after 6 weeks, but you have to do physio therapy. And keep doing that for about half a year or something.
If you need surgery, and you get plates, you can start maybe sooner, cause with the plates it is hard. But with plates there is a chance you break the plate, cause bones bend normally, and plates don't'.
Do not eat spinach, there is something in there that will slow the making of cardelich (?) in your body.
If you want to make the break hard again, fitness, but be carefull for an extra joint. This will happen if the break hasnt healed properly and you get an extra pivot or something at that place, but with a plate this will not be the case.
