Broken leg. External frame pinned to a man's fractured leg. His leg was broken by a runaway wheel that struck him from behind after coming off a car as it sped around a corner. Following an X- ray, the fractured bones were realigned and immobilized with this external frame. Unfortunately, the frame led to septicaemia, tissue death caused by the absorption of disease- causing bacteria or their toxins from the blood. The infection is being treated with injections of antibiotics.
