A broken foot is an injury to the bone. You may experience a broken foot during a car crash or from a simple misstep or fall.

The seriousness of a broken foot varies. Fractures can range from tiny cracks in your bones to breaks that pierce your skin.

Treatment for a broken foot depends on the exact site and severity of the fracture. A severely broken foot may require surgery to implant plates, rods or screws into the broken bone to maintain proper position during healing.

If you have a broken foot, you may experience some of the following signs and symptoms:

• Immediate, throbbing pain
• Pain that increases with activity and decreases with rest
• Swelling
• Bruising
• Tenderness
• Deformity
• Difficulty in walking or bearing weight

When to see a doctor

See a doctor if there is obvious deformity, if the pain and swelling don't get better with self-care, or if the pain and swelling gets worse over time. Also, see a doctor if the injury interferes with walking.

The most common causes of 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 feet, as can landing on your feet after jumping down from just a slight height.
• 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. A toe can get broken from stubbing your toes on furniture.
• Overuse. Stress fractures are common in the weight-bearing bones of your 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.

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 sports such as basketball, football, gymnastics, tennis and soccer can causes foot fractures.
• Use improper technique or 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 injuries.
• Suddenly increase your activity level. Whether you're a trained athlete or someone who's just started exercising, suddenly boosting the frequency or duration of your exercise sessions can increase your risk of a stress fracture.
• 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 injuries.
• Have certain conditions. Having decreased bone density (osteoporosis) can put you at risk of injuries to your foot bones.

Complications of a broken foot are uncommon but may include:

• Arthritis. Fractures that extend into a joint can cause arthritis years later. If your 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.
• Nerve or blood vessel damage. Trauma to the foot 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 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. If you're a runner, replace your sneakers every 300 to 400 miles.
• 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.

During the physical exam, your doctor will check for points of tenderness in your foot. The precise location of your pain can help determine its cause.

They may move your foot into different positions, to check your range of motion. You may be asked to walk for a short distance so that your doctor can examine your gait.

Imaging tests

If your signs and symptoms suggest a break or fracture, your doctor may suggest one or more of the following imaging tests.

• X-rays. Most foot fractures can be visualized on X-rays. The technician may need to take X-rays from several different angles so that the bone images won't overlap too much. Stress fractures often don't show up on X-rays until the break actually starts healing.
• Bone scan. For a bone scan, a technician will inject a small amount of radioactive material into a vein. The radioactive material is attracted to your bones, especially the parts of your bones that have been damaged. Damaged areas, including stress fractures, show up as bright spots on the resulting image.
• Computerized tomography (CT). CT scans take X-rays from many different angles and combine them to make cross-sectional images of internal structures of your body. CT scans can reveal more detail about the bone and the soft tissues that surround it, which may help your doctor determine the best treatment.
• Magnetic resonance imaging (MRI). MRI uses radio waves and a strong magnetic field to create very detailed images of the ligaments that help hold your foot and ankle together. This imaging helps to show ligaments and bones and can identify fractures not seen on X-rays.

Treatments for a broken foot will vary, depending on which bone has been broken and the severity of the injury.

Medications

Your doctor may recommend an over-the-counter pain reliever, such as acetaminophen (Tylenol, others).

Therapy

After your bone has healed, you'll probably need to loosen up stiff muscles and ligaments in your feet. A physical therapist can teach you exercises to improve your flexibility and strength.

Surgical and other procedures

• Reduction. If you have a displaced fracture, meaning the two ends of the fracture are not aligned, your doctor may need to manipulate the pieces back into their proper positions — a process called reduction. Depending on the amount of pain and swelling you have, you may need a muscle relaxant, a sedative or even a general anesthetic before this procedure.

• Immobilization. To heal, a broken bone must be immobilized so that its ends can knit back together. In most cases, this requires a cast.

  Minor foot fractures may only need a removable brace, boot or shoe with a stiff sole. A fractured toe is usually taped to a neighboring toe, with a piece of gauze between them.

• Surgery. In some cases, an orthopedic surgeon may need to use pins, plates or screws to maintain proper position of your bones during healing. These materials may be removed after the fracture has healed if they are prominent or painful.

You will likely initially seek treatment for a broken foot in an emergency room or urgent care clinic. If the pieces of broken bone aren't lined up properly for healing, you may be referred to a doctor specializing in orthopedic surgery.

What you can do

You may want to write a list that includes:

• Detailed descriptions of your symptoms
• Information about medical problems you've had
• Information about the medical problems of your parents or siblings
• All the medications and dietary supplements you take
• Questions you want to ask the doctor

For a broken ankle or foot, basic questions to ask your doctor include:

• What tests are needed?
• What treatments are available, and which do you recommend?
• If I need a cast, how long will I need to wear it?
• Will I need surgery?
• What activity restrictions will need to be followed?
• Should I see a specialist?
• What pain medications do you recommend?

Don't hesitate to ask any other questions you have.

What to expect from your doctor

Your doctor may ask some of the following questions:

• Was there a specific injury that triggered your symptoms?
• Did your symptoms come on suddenly?
• Have you injured your feet in the past?
• Have you recently begun or intensified an exercise program?

What to do in the meantime

If your injury isn't severe enough to warrant a trip to the emergency room, here are some things you can do at home to care for your injury until you can see your doctor:

• Apply ice for 15 to 20 minutes at a time, every three to four hours to bring down the swelling.
• Keep your foot elevated.
• Don't put any weight on your injured foot.
• Lightly wrap the injury in a soft bandage that provides slight compression.
