Among the femoral neck fractures, unilateral injury is the most common presenting feature.1 In the younger population, it is a result of high energy trauma from road traffic accidents or falls from height.1,2 In the elderly population, a simple fall results in a fracture of the osteoporotic bone.3 But a patient sustaining a bilateral neck of femur fracture without any trauma is a rare occurrence.4 We recently received a 78-year-old male patient who sustained a nontraumatic bilateral neck of femur fracture following a single episode of a generalized tonic-clonic seizure. He is a known chronic obstructive pulmonary disease patient and recovered from COVID pneumonia 6 months back. The patient underwent modular cemented bipolar hemiarthroplasty for both hips as a staged procedure, and the patient was made for walking full weight-bearing from the second postoperative after the second hip was operated.
