RESUMEN
BACKGROUND: Stress fractures of the femoral neck are uncommon. They are caused by either excessive stress or bone fragility. AIM: To report a case of bilateral stress fracture of the femoral neck in a 15-year-old girl without any risk factors OBSERVATION: We report a case of bilateral stress fracture of the femoral neck in a 15-year-old girl in whom no risk factors were found. One of the fractures was displaced at first diagnosis and was successfully treated by closed reduction and valgus subtrochanteric osteotomy. The other fracture was initially undisplaced but displacement occurred later despite internal fixation with a dynamic hip screw. CONCLUSION: A high index of suspicion of stress fractures of the femoral neck must be kept in mind even without risk factors. Delays in diagnosis and displacement should therefore be avoided.
