Introduction and importanceBilateral femoral neck fractures in young adults are a rare entity. It is usually associated with pre-existing metabolic diseases, such as osteoporosis, renal osteodystrophy, or hypocalcemic seizures. Hence, it is essential in such cases to look for other associated injuries following a traumatic event. Missing associated injuries may lead to significant morbidities and poor functional outcomes.Case presentationA 37 years old male, who had chronic renal failure secondary to hypertension, and presented to the emergency room following a seizure episode, in which he developed a generalized tonic-clonic convulsion secondary to electrolyte imbalances with metabolic acidosis. As a result, he developed bilateral neck of femur fracture.Intervention and outcomeThe medical team optimized electrolytes imbalance and then the patient underwent surgical stabilization of both femur neck fracture, 1 year following the surgical fixation the patient had full range of motion of both hips with radiological evidence of complete healing of the fracture.ConclusionIn cases of fractures secondary to metabolic conditions, bilateral femoral neck fractures should be suspected and investigated; especially in young patients who develop a generalized tonic-clonic seizure. The etiology is multifactorial, and the treating surgeon should be aware of predisposing factors which may affect bone quality, thereby raising the risk of fractures even with low-energy atraumatic events. Hip preservation should always be the primary target when treating these patients.
