Two cases of lengthening of metatarsals by distraction osteogenesis are reported. One of these cases is an acquired deformity of the first metatarsal; the other is a congenital short fourth metatarsal. By following the principles set forth by llizarov, it was possible to lengthen the metatarsal bones and surrounding soft tissues without open lengthening of tendons or secondary bone grafting of the distraction gap. We believe this method is an improvement over previously described methods of metatarsal lengthening.
