What is a stress fracture and how does it happen?
A stress fracture is a common overuse injury most often seen in athletes. A stress fracture occurs when the force of an injury is lower than say a car accident or bad fall, but happens repetitively for a long period of time; these injuries are also known as "fatigue fractures." Stress fractures are commonly seen in athletes who run and jump on hard surfaces, such as distance runners, basketball players, and ballet dancers.
Stress fractures are usually seen in athletes who increase their level of activity over a short period of time. The increased demand placed on the bone causes the bone to remodel and become stronger in the areas of higher stress. However, if the response of the bone cannot maintain the pace of the repetitive demands, a stress fracture may result.
