Spontaneous bilateral femur neck fracture secondary to grand mal seizure: A case report

BACKGROUND: Spontaneous bilateral femur neck fracture is a rare entity in the general population. CASE SUMMARY: A 17-year-old immobile, developmentally delayed male with the sequelae of cerebral palsy fractured both femoral necks during a grand mal epileptic seizure. He had been treated with valproic acid as an antiseizure medication for about 10 years; otherwise, he had no history of drug use. The laboratory analysis was normal except a marked vitamin D deficiency. Closed reduction and osteosynthesis with percutaneous cannulated screws were performed. Solid union was observed at 6 mo, and rapid postoperative rehabilitation was started. CONCLUSION: A femoral neck fracture may occur in a person with epilepsy presenting with hip pain in the emergency department.
