Simultaneous bilateral neck of femur fractures in an adolescent secondary to hypocalcaemic seizure.

We present a rare case of a previously healthy 16-year-old boy who sustained simultaneous bilateral femoral neck fractures after a single first-time seizure episode. He was diagnosed to have severe vitamin D deficiency and secondary hyperparathyroidism. Symptomatic hypocalcemia was the cause of seizures. Both fractures were treated surgically and united at 3 months. Bilateral femoral neck fractures after seizures are very rare, especially in children. Severe vitamin D deficiency may cause seizures and also weakening of bone, predisposing to fractures without significant trauma. We recommend that paediatric cases of femoral neck fractures after seizures should be investigated for underlying metabolic disease.
