Risk factors

You may be at higher risk of a broken 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 cause ankle 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 ankle 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.
• 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 ankle injuries.
• Have certain conditions. Having decreased bone density (osteoporosis) can put you at risk of injuries to your ankle bones.
• Smoking. Cigarette smoking can increase your risk of developing osteoporosis. Studies also show that healing after a fracture may take longer in people who smoke.
