Introduction. Scoliosis has been associated with thoracic cavity alterations that impair pulmonary function. Correcting sco-liotic deformity regains normal pulmonary function by maintaining respiratory and muscular efficiency. This study aims to com-pare pulmonary function and thoracic volume at baseline and after correcting the scoliosis deformity.Methods. A total of 56 patients, 46 girls and 10 boys, were diagnosed with idiopathic scoliosis. Participants were randomly allocated into two equal groups. Group A was treated with posterior correction, vertebral derotation, and a pulmonary rehabilita-tion program, while group B was treated with the same treatment given to group A without derotation. Evaluation of the measur-ing variables was carried out pre-operatively, immediately post-operatively, and three months after the operation. In addition, post-operatively, participants were treated with segmental breathing exercise training and incentive spirometry, 3 sessions per week for 3 months.Results. A significant reduction in the Cobb angles, angles of rotation, and chest expansion was observed in both groups by comparing both initial and post-operative mean values, while a significant reduction was revealed in group A (p = 0.0001). The mean values of FEV1 and MVV immediately post-operatively showed a significant reduction in both groups, which was highly significant for group A. At three months post-operatively, both groups showed highly significant improvement (p = 0.001).Conclusions. In addition to its beneficial effects on curve correction and the angle of rotation, the vertebral derotation tech-nique impairs physiological and mechanical parameters immediately post-operatively. However, a beneficial effect was detected after three months of pulmonary rehabilitation in all parameters.
