I would like to know how long is surgery for orif for a right broken fibula, it is the lower part of the fibula close to the ankle?

1.5 hours : The distal part or end of the fibula is near the ankle.

Hour or less: If you have a fractured fibula the average time would be about an hour or less (typically 30-40 minutes). I don't really focus on the length but quality of care done. Obviously if your surgeon takes more than a couple hours that is a bit too long as greatly increases risk of infection and lengthens tourniquet time which can cause other issues.
