Stress Fractures


What are Stress Fractures?

Stress fractures are different from a typical fracture and generally occur in a physically active person.

  1. Regular fractures:  Typically involve one specific injury to the bone normally from a direct blow
  2. Stress fractures: Occur over a longer period of time as a result of repetitive application of stresses that weaken the outer surface of the bone.


What Causes Stress Fracture

Stress fractures are a result of repetitive application of stresses that is lower than the stress required to fracture the bone.

Over a period of time this stress results in injury to the cortex of the bone this is called a stress fracture.

Romani et al. 2002 (1) provides an excellent in depth explanation of the mechanism of what causes a stress fracture (click here for the article)


Risk factors for Foot and Ankle Stress fractures

Extrinsic risk factors Intrinsic risk factors
– Running surface (1,17) – Female (7, 23)
– Type of exercise (1, 10, 17) – Smoking (23)
 – Inadequate recovery period (22) – Older age (20)
–  Footwear (1) – Family history (17)
– Altered foot mechanics (1)
– Previous Stress fractures (3, 7, 14)
– Poor nutrition (25)

Complications of  Stress fractures

A complication of Metatarsal stress fracture is that if left unchecked can result in a complete fracture of the metatarsal.
