Neglected bilateral femoral neck fracture associated with pregnancy and primary hyperparathyroidism.

We report a case of neglected bilateral femoral neck fracture related with transient osteoporosis in pregnancy (TOP) and primary hyperparathyroidism, in a 33-year-old female who presented with a fracture of both femoral necks without any history of trauma 20 days after delivery. Her pain was at first accepted as common musculoskeletal discomfort following labour, and the final diagnosis was made only 25 days after fracture. She was treated with primary internal fixation with cannulated lag screws and received medical treatment for hyperparathyroidism and TOP. She was followed up for 29 months following the operation. No complications, and more specifically no avascular necrosis (AVN) were noted during this time interval. The patient made a complete functional recovery. We would like to emphasize that major medical problems may be underdiagnosed during the last pregnancy trimester and postpartum period. Delay in the diagnosis and treatment of a femoral neck fracture is an important but not a decisive factor for the development of AVN.
