This is the area of greatest impact on your foot as you push off when you walk or run. Stress fractures occur most often in the second and third metatarsals in the foot, which are thinner (and often longer) than the adjacent first metatarsal. Which Bones Are Affected By a Stress Fracture? However, continually bending it back and forth, the metal will weaken and eventually break. If you gently bend a paper clip once, it will not break. The forces that cause a stress fracture in the foot or ankle are similar to those when you bend a paper clip. Runners have a higher than average risk of tibial stress fractures, and activities that involve a lot of stress on the forefoot, such as dancing or track and field, bring an increased risk of stress fractures of the metatarsals or navicular bone of the foot. In a stress fracture, the bone breaks but usually does not shift position (become “displaced”). Stress fractures are common in foot and ankle bones because we continually place force on them by standing, walking, running and jumping. It differs from a typical broken bone caused by a sudden injury in that a stress fracture develops in response to chronic stress on the bone. What is a Stress Fracture?Ī stress fracture is a type of bone break or crack in the bone that occur when a small or moderate amount of force is applied to a bone repeatedly and over time. However, they do come with a few symptoms that should prompt a trip to the doctor’s office. Diagnosis is typically confirmed with imaging scans such as an X-ray or MRI. Stress fractures can be difficult to identify. The repetitive force that causes a stress fracture is not great enough to cause an acute fracture - such as a broken ankle caused by a fall. They occur over time when repetitive forces result in microscopic damage to the bone. Stress fractures, also known as hairline fractures, are quite common in the feet and ankles of athletes and people who engage in repetitive movements or spend a lot of time standing since many stress fractures are overuse injuries. ![]()
