title: Atraumatic diplaced bilateral femoral neck fracture in a patient with hypophosphatemic rickets in postpartum period: A missed diagnosis.
abstract: BACKGROUND
  Simultaneous bilateral femoral neck fracture is an uncommon condition. There are very few cases reported in the literature and most of these cases have underlying bone pathologies such as renal osteodystrophy and osteomalacia. In some cases bilateral femoral neck fractures occur due to generalized seizures or high-energy trauma.
  
  
  METHODS
  In this case report "atraumatic bilateral femoral neck fracture in a 26year old woman in postpartum period with hypophosphatemic rickets disease" is presented.
  
  
  CONCLUSIONS
  Femoral neck fractures are more frequently seen in elderly because of the reduction of bone quality and developing osteoporosis. In the literature generalized epilepsy, osteomalacia, hypovitaminosis D and chronic renal failure are shown as facilitating causes of bilateral femoral neck fractures. In patients without any additional pathology electric shock, electroconvulsive therapy, and high-energy trauma can lead to femoral neck fractures. In our patient there was also an underlying pathology, she has been followed due to autosomal recessive hypophosphatemic rickets disease since she was one year old. In the treatment of bilateral femoral neck fractures open/closed reduction internal fixation or hip arthroplasty are applied.
  
  
  CONCLUSIONS
  For patients with bone metabolic diseases and/or the patients in pregnancy and postpartum period, preventive measures should be increased to reduce the risk of pathologic fracture. Admitting to the hospital physicians must be more careful about detecting fractures in these patients.
