How does the Ilizarov procedure lengthen the bone?
Progressive distraction across the osteotomy site, with preserved periosteum, leads to osteogenesis across the intervening gap, thus lengthening the bone. With the distracted gap actively increased by 1mm/day, the physician can accurately achieve the desired bone length.
