Foot

What It Is

Stress fractures are small cracks in the bone. They often happen through overuse, when a movement is repeated so often, for example in basketball or distance running, that the bone does not have enough time to recover between sessions (AAOS, n.d.). Most of these fractures occur in the weight-bearing bones of the lower leg and the foot, and in the foot the metatarsals are the most common site (AAOS, n.d.). Studies indicate that athletes taking part in track and field, tennis, dance, gymnastics and basketball are at increased risk of these fractures; ballet dancers are at particularly high risk of metatarsal stress fractures (AAOS, n.d.). In these sports, the repeated stress of the foot hitting the ground can cause problems.

Rest from the activity that caused it is a key part of recovering from one of these fractures.

These fractures often occur when you suddenly increase high-impact activity in terms of intensity, frequency or duration, either in training or by doing "too much, too soon" (AAOS, n.d.; Cambridge University Hospitals NHS Foundation Trust, 2024). People who don't exercise can still get these fractures. If osteoporosis or another condition has weakened the bones, normal everyday activities can cause a stress fracture; this is known as bone insufficiency (AAOS, n.d.).

The second and third metatarsals are the most prone to stress fractures. Fractures of the fourth and fifth metatarsals are less common, but the base of the fifth metatarsal has a poor blood supply, so fractures there can take longer to heal (AAOS, n.d.).

Metatarsal Stress Fracture Anatomy

In each foot, you have five metatarsal bones running from the toe joints to the arch. The second and third metatarsals are thinner (and often longer) than the first metatarsal, and they sit in the area of greatest impact when you push off to walk or run (AAOS, n.d.). Stress fractures of these bones typically cause pain through the middle of the foot, while fractures of the fourth and fifth metatarsals cause pain on the outside of the foot (AAOS, n.d.).

Bone is constantly being broken down and renewed. With too much activity, the breakdown of older bone can happen faster than the body can repair and replace it, so the bone weakens and becomes vulnerable to stress fractures (AAOS, n.d.).
