Is the fracture displaced or non-displaced? That's what I'm looking for. If it's non-displaced, surgery is usually not necessary. If there is surgery, it's a sign the fracture is displaced enough so they don't want it to heal as is. They need to reset the bones.
Non-displaced is 6 weeks to walking. My wife had a non displaced ankle fracture, and it took that long. You just wear a boot. Many years ago, I had a severe ankle dislocation. No fracture. It looked pretty grotesque--like Hayward's looked. But the Doc just snapped it back in place, put a plaster cast on over the knee, and I walked around in a rubber boot for 6 weeks.
If there's surgery here, it will be longer than 6 weeks. Maybe 10 weeks. And then longer to get back onto the court. Double that. Make it 5-6 months.
You don't feel any pain right away with these things. The next day you feel pain, and they give you pain killers (codeine in my day, which makes you feel great!).
