The Ilizarov Frame

Professor Gavril Abramovich Ilizarov was born in the Caucasus, in the Soviet Union in 1921. Although not formally trained as a surgeon, but being the only doctor in the area, he was regularly confronted with a wide variety of orthopaedic problems. It was during this time that, in the 1950s, he devised and developed his revolutionary method for treating fractures, deformities and other bone defects. This involved the use of a circular external fixator. During the next decade his research led him to the techniques of physeal distraction, corticotomy lengthening, bone transport and others.
