Abstract

Marfan syndrome is an autosomal dominant and could decrease bone mineral density. So patients with Marfan syndrome could vulnerable to trauma in old ages. We present the first report, to the best of our knowledge, of a rare fracture of the femoral neck with a minor traumatic history in a juvenile Marfan syndrome patient whose physis is still open. Although the patient is young, her bone mineral density was low and the geometry of femur is changed like old ages. The femur neck fracture in children is very rare and only caused by high energy trauma, we concluded that the Marfan syndrome makes the bone weaker in young age and preventative medications to avoid fractures in younger Marfan syndrome patients are necessary in early ages.
