If you have a broken ankle or broken foot, you may experience some of the following signs and symptoms:
- Immediate, throbbing pain
- Pain that increases with activity and decreases with rest
- Difficulty in walking or bearing weight
- Problems getting a shoe on or off
Some people feel or hear a snap at the time of injury and assume that means something has broken. However, a snapping sound or feeling is not always a sign of a fracture.
When to see a doctor
See a doctor if the pain and swelling last for more than two or three days, or if pain interferes with walking.
The most common causes of a broken ankle or a broken foot include:
- Car accidents. The crushing injuries common in car accidents may cause breaks that require surgical repair.
- Falls. Tripping and falling can break bones in your ankles or feet, as can landing on your feet after jumping down from several feet off the ground.
- Impact from a heavy weight. Dropping something heavy on your foot is a common cause of fractures.
- Missteps. Sometimes just putting your foot down wrong can result in a broken bone. Many broken toes have happened when people stub their toes on furniture. Twisting your ankle just right can cause a sprain or a broken bone.
- Overuse. Stress fractures are common in the weight-bearing bones of your ankles or feet. These tiny cracks are usually caused over time by repetitive force or overuse, such as running long distances. But they can also occur with normal use of a bone that's been weakened by a condition such as osteoporosis or a stress fracture.
You may be at higher risk of a broken foot or ankle if you:
- Participate in high-impact sports. The stresses, direct blows and twisting injuries that occur in football, hockey, gymnastics, ballet, tennis, soccer, skiing and snowboarding are causes of foot and ankle fractures.
- Use improper sports equipment. Faulty equipment, such as shoes that are too worn or not properly fitted, can contribute to stress fractures and falls. Improper training techniques, such as not warming up and stretching, also can cause foot and ankle injuries.
- Work in certain occupations. Certain work environments, such as a construction site, put you at risk of falling from a height or dropping something heavy on your foot.
- Keep your home cluttered or poorly lit. Walking around in a house with too much clutter or too little light may lead to falls and foot and ankle injuries.
- Have certain conditions. Having fragile bones (osteoporosis) or poor sensation in your feet (neuropathy) can put you at risk of injuries to your foot and ankle bones.
- Are a female athlete. Female athletes often restrict their diets, which can lead to irregular menstrual periods and osteoporosis. This is known as the female athlete triad. Taken together, this can put these athletes at higher risk for foot or ankle stress fractures.
Complications of a broken ankle or broken foot are uncommon, but may include:
- Arthritis. Fractures that extend into the joint can cause arthritis years later. If your ankle or foot starts to hurt long after a break, see your doctor for an evaluation.
- Bone infection (osteomyelitis). If you have an open fracture, meaning one end of the bone protrudes through the skin, your bone may be exposed to bacteria that cause infection.
- Compartment syndrome. This condition causes pain, swelling and sometimes disability in affected muscles of the legs or arms. Compartment syndrome usually occurs in high-impact injuries, such as a car or motorcycle accident.
- Nerve or blood vessel damage. Trauma to the foot or ankle can injure adjacent nerves and blood vessels, sometimes actually tearing them. Seek immediate attention if you notice any numbness or circulation problems. Lack of blood flow can cause a bone to die and collapse.
These basic sports and safety tips may help prevent a broken ankle or broken foot:
- Wear proper shoes. Use hiking shoes on rough terrain. Wear steel-toed boots in your work environment if necessary. Choose appropriate athletic shoes for your sport.
- Replace athletic shoes regularly. Discard sneakers as soon as the tread or heel wears out or if the shoes are wearing unevenly.
- Start slowly. That applies to a new fitness program and each individual workout.
- Cross-train. Alternating activities can prevent stress fractures. Rotate running with swimming or biking.
- Build bone strength. Calcium-rich foods, such as milk, yogurt and cheese, really can do your body good. Taking vitamin D supplements also can help.
- Use night lights. Many broken toes are the result of walking in the dark.
- Declutter your house. Keeping clutter off the floor can help you to avoid trips and falls.
- Strengthen your ankle muscles. If you are prone to twisting your ankle, ask your doctor for exercises to help strengthen the supporting muscles of your ankle.
