The most common causes of a broken ankle or a broken foot include:

  • Car accidents. The crushing injuries common in car accidents may 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 a great 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. 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.
