Hello, Thanks for your query. More severe fractures can be exceptionally painful and will require more medical attention. They may also be treated in the same manner as a hairline fracture, though a cast is likely to be put on the leg to prevent excess movement, and the healing time may be fairly prolonged. The most severe distal fibula fractures may require surgery to repair the bone using plates and screws; if the bone has ruptured any surrounding soft tissue, they may also need to be repaired during the surgery. Recovery time from such an injury can be quite long. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
