The authors present sixteen patients with congenital kyphosis treated by posterior spinal arthrodesis. A homologous or autogenous iliac bone graft was used. The patients walked with Risser-Cotrel body cast in the 6 months of postoperatory period. The mean time of follow-up was 58,25 months and the mean age of the patients at time of surgery was 9,3 years. The mean angular value of the congenital kyphosis before surgery was 50,44º Cobb and after ther surgery it was 46,94º Cobb. One of the patients who had curve of 69º Cobb, presented pseudoarthrosis. The final results were good in 10, regular in 4 and bad in 2 patients. The need of the diagnostic and precocious treatment is recommended by authors.
