Background: In this study we evaluated lung volumes, volume changes relative to Cobb angle and correlation of volume changes with Cobb angle changes before and after the surgery. Materials and Methods: Eighteen non-smoker patients with idiopathic scoliosis were included in this descriptive observational study. Cobb angle, lung volume and flow were measured before and after the surgery. To assess height and weight changes during the tollow-up period, we used the percent relative to normal (percent predicted) instead of absolute volumes. Results: Eighteen of 30 selected patients were included. The mean foHow-up period was 34.5±19.6 months. Dynamic volume changes of lung were: VC::: -13.4 50:::8.6 (p<0.005); FVC:::-9.22 50:::14 (p
