A stress fracture is a bony overuse lesion resulting from an imbalance between the osseous regeneration and resorption in favor of the second one. There are two different types, the fatigue fracture that affects mainly the young and active and appears after an abrupt increase of the constraints, and the insufficiency fracture that affects mainly the elderly suffering from a diminished bone density and appears typically during physiological constraints. A thorough screening of the patient's history is mandatory in diagnostics, and MRI is currently the imagery of choice. As the treatment is time consuming and depends on the risk of potential complications that may occur depending on the localization of the fracture, prevention is of key importance and requires a multidisciplinary approach.
