The Ilizarov apparatus is a type of external fixation used in orthopedic surgery to lengthen or reshape limb bones; to treat complex and/or open bone fractures; and in cases of infected nonunions of bones that are not amenable with other techniques. It is named after the orthopedic surgeon Gavriil Abramovich Ilizarov from the Soviet Union, who pioneered the technique.
