A Prospective Evaluation of Pulmonary Function in Patients With Adolescent Idiopathic Scoliosis Relative to the Surgical Approach Used for Spinal Arthrodesis

1) Patients with chest cage disruption during surgical treatment showed a decline in pulmonary function at 3 months after surgery. 2) In contrast, patients without chest cage disruption showed an improvement in pulmonary function at 3 months after surgery. 3) Irrespective of the surgical approach used for spinal arthrodesis, postoperative pulmonary function tests (absolute values) returned to preoperative values at 2 years after surgery. 4) Patients who had no chest cage disruption experienced a significantly greater improvement in two of their pulmonary function values at 2 years after surgery than patients with chest cage disruption.
