19 idiopathic and 1 syringomyelia scoliosis patients (17 females and 3 males) underwent fusionless, multiple vertebral wedge osteotomy and with follow-up for an average of 8.9 years. The average age at surgery was 16.4 years. The average curve magnitude measured by Cobb was 64.0 degrees before surgery, 38.8 degrees after surgery, 43.7 degrees one year after surgery, 46.9 degrees two years after surgery and 48.2 degrees at the latest follow-up. The difference between the Cobb angle two years after surgery and latest follow-up was not significant. There were no major complications such as neurological problems.
