Forty-six patients with congenital pseudarthrosis of the leg were
followed for twelve years or more. Forty of these patients were examined,
interviewed, or both from 1974 to 1975. Congenital pseudarthrosis is a
condition most often combined with neurofibromatosis. In neurofibromatosis
the prognosis of the pseudarthrosis is dependent on the roentgenographic
type. Of the procedures used, insertion of intramedullary rods and grafting
gave the highest rate of union. Atrophy, shortening, valgus deformity, and
limited range of motion complicated the functional results.
