I've battered my ankle a few times, but never had an x-ray, but may have fractured it at least once. It has been a while, but I think I was riding my bike fairly quickly.
One has the Tibia and Fibula, talus, and calcaneus. For the leg bones, the Tibia bears most of the weight, while the Fibula helps provide some stability and flexibility to the joint, I think. Then, of course, the talus and calcaneus also are weight bearing.
So, with say a non-displaced partial Fibula fracture, you might be able to return to weight bearing fairly quickly.
Other bones? It would depend on the bone and fracture.
Your doctor should have the data to give you better information about what happened to your ankle, and what you should be able to do. But, of course, you'll know pretty quickly if you can go weight bearing.
