10-Jahresverläufe nach Harrington-Operation bei kongenitalen, Poliomyelitis- und Neurofibromatose-Skoliosen

From 1972 through 1976 40 patients with congenital scoliosis, scoliosis in neurofibromatosis and scoliosis following poliomyelitis underwent posterior spine fusion using Harrington instrumentation. Follow up was 10 years or more with an average of 12 years. 63 percent of all patients showed a curve of more than 90 degrees before operation. The different types of scolioses revealed characteristical results according to their etiology during long time follow up. Concerning long time reduction of curve the best results were obtained in patients following poliomyelitis. Patients with congenital and neurofibromatous scoliosis showed loss of correction 2 and 5 years postoperatively.
