With proper treatment, fibula fractures heal within four to six weeks, according to Baylor Scott & White Health. Fibula fractures are painful but seldom serious because this small lower-leg bone only supports 17 percent of the body's weight.
Treatment for a broken fibula includes elevation of the break, ice and anti-inflammatory medication to control swelling, reports Baylor Scott & White Health. Patients typically use crutches for walking while the break heals. Doctors may also fit patients with a walking boot or brace to restrain the injury for healing. Once the patient removes the restraint, he should begin exercises to strengthen the muscles and improve range of motion.
