Stress fracture overview

A stress fracture is one type of incomplete fracture in bones. It is caused by “unusual or repeated stress”^[1] This is in contrast to other types of fractures, which are usually characterized by a solitary, severe impact.

It could be described as a very small sliver or crack in the bone; this is why it is sometimes dubbed “hairline fracture”. It typically occurs in weight-bearing bones, such as the tibia (bone of the lower leg) and metatarsals (bones of the foot).

It is a common sports injury, and more than half of the cases are associated with athletics.^[2]

Stress fractures usually have a narrow list of symptoms. It could present as a generalized area of pain, tenderness, and pain with weight-bearing. Usually when running, a stress fracture has severe pain in the beginning of the run, moderate pain in the middle of the run, and severe pain at the end and after the run.

With severe stress fractures, surgery may be needed for proper healing. The procedure may involve pinning the fracture site, and rehabilitation can take up to a half year.
