[Congenital pseudoarthrosis of the leg - classification and treatment.]

Congenital pseudoarthroses of the leg do not have a uniform etiology, clinical course, location nor affection of the fibula. As in any other congenital defect, treatment is very difficult and achievement of perfect functional and anatomical results is rather wishful thinking than reality. In the submitted paper the authors discuss different classifications - according to Andersen, Boyd, Campanacci and Crawford. The authors present their own modification of Boyd's method of a dual cortical graft, which involves taking a graft from one of the parents. At the authors department a total of 12 children with 12 inborn pseudoarthroses of the leg were operated. The results were evaluated in eight patients, using the EPOS method. The mean period of hospitalization was 135 days, the mean number of hospitalizations 7.5, the mean number of operations per patient was 4.7; treatment took on average 17.5 months. Excellent results were achieved three times, "tenuous healing" twice, severe restriction of the talus was recorded in two patients. One congenital pseudoarthrosis was not cured successfully so far. Key words: congenital pseudoarthrosis, leg, classification, dual cortical graft.
