Scoliosis surgery in patients with adolescent idiopathic scoliosis does not alter lung volume: a 3-dimensional computed tomography-based study.

Study Design: Retrospective study of surgically treated patients with adolescent idiopathic scoliosis.

Objective: To determine the change in lung volume after the surgical correction of scoliosis using a volumetric reconstruction of lung volume from computed tomographic (CT) scans.

Summary Of Background Data: Previously published studies have shown that pulmonary function tests improve after scoliosis correction; however, these results are not consistent.
