[Fatigue fracture of both femoral necks ina 19-year-old woman (author's transl)].

A case of slow fracture of both femoral heads in a 19-year-old woman is reported. The radiological characteristics, clinical context and onset in a histologically normal skeleton were in favour of a diagnosis of fatigue fracture. Data in the literature show the rarity of this condition affecting the neck of the femur in the young woman and rarely mention the existence of morphological abnormalities as a favouring factor.
