The purpose of the present study was to investigate the effect that corrective surgery for scoliosis would have on pulmonary function as well as the circumference of the chest. As a result, the current investigation was carried out on thirty individuals who had idiopathic scoliosis and had been admitted to the hospital. Before the surgery, after it had been completed (on the fifth day), and again three months later, the pulmonary function was tested.
