Due to the thick cortical structure, subtrochanteric fractures of femur is often caused by high energy trauma and there are only a few report of it from low energy trauma. We have experienced a case of bilateral subtrochanteric fracture which oc-curred after a simple slip down. The fracture was healed with applying intramedullary nail. We believe the fracture may have occurred from prolonged use of steroid which was used to treat underlying rheumatoid arthritis.
