In 34 patients with scoliosis; using CT, a new method was proposed to evaluate the change in rotation precisely. The angle of rotation of the apical vertebra was measured by taking the neutral vertebra as a reference point. In this method, the influence of the patients rotational relationship to the radiographic table was minimized. The results were compared with the Nash-Moe and Aaron-Dahlborn's methods and significant corralations were found. This study illustrates a more precise method which facilitates the three dimensional analysis of scoliosis.
