Bicycle spoke fracture.
Twenty-nine children were treated for bicycle spoke injury, which occurred while they were sitting behind their riding parents. Their feet were caught in between the bicycle spoke and the frame rod. Five of these children suffered supramalleolar fracture. These fractures had a similar radiographic pattern, namely a greenstick fracture of the distal end of the tibia and fibula, buckling into varus and usually also into anterior angulation. Healing of the fractures was uneventful. These injuries are preventable by rigid plastic net covers for the rear wheel of the bicycle.
