骨延长的概念于1905年由Codivilla首先提出,他在股骨上作一斜行切口,通过快速强拉骨钉或以oscalcis驱动的钢柱施加反复轴形牵引力而使股骨延长。35年后,苏联学者Ilizarov发明了牵引或延长骨痂形成新骨的技术。通过缓慢牵引术使下颌骨延长,文献上已有实验研究报道。Constantino等(1990)最近报道以牵引 The concept of osteotomy was first proposed by Codivilla in 1905 to make an oblique incision in the femur to prolong the femur by rapidly pulling the bone or applying repeated axial traction to the oscalcis-driven steel column. Thirty-five years later, Soviet scholar Ilizarov invented the technique of pulling or extending callus into new bone. By slow traction mandibular extension, the literature has been reported in experimental studies. Constantino et al. (1990) recently reported traction
