Treatment of congenital pseudarthrosis with the Ilizarov technique.

Four patients with congenital pseudarthrosis in neurofibromatosis were treated with percutaneous transosseous fixation according to the Ilizarov method. Three tibias were first treated unsuccessfully with a Sofield procedure. After application of the Ilizarov fixator, consolidation was obtained in two cases after 6 and 19 months, respectively. A fourth case consisted of a congenital pseudarthrosis of the ulna, primarily treated with the Ilizarov system, which showed advanced consolidation after 4 months.
