The fibula articulates with the other lower leg bone, the tibia just below the knee; the lower end forms the projection that may be felt on the outer side of the ankle. The main function of the fibula is to provide an attachment for muscles. It provides little supportive strength to the lower leg, which is why pieces of bone can safely be taken from it for grafting elsewhere in the body. Fractures of the fibula The fibula is one of the most commonly broken bones. Fracture of the fibula just above the ankle may occur with a severe ankle sprain as a result of a violent twisting movement. Pott's fracture is fracture of the fibula just above the ankle combined with dislocation of the ankle and sometimes with fracture of the tibia. A suspected fracture of the fibula is X-rayed to confirm the diagnosis. In some cases the lower leg is immobilized in a plaster cast to allow the bone to heal. If the fracture occurs in the middle portion of the fibula, immobilization may not be needed. If the fracture is severe (especially if it is accompanied by dislocation of the ankle), surgery may be necessary to fasten the broken pieces of bone with metal pins. A fractured fibula may take up to six weeks to heal, depending on its severity and the age of the patient.
