Impact of fusion for adolescent idiopathic scoliosis on lung volume measured with computed tomography

Purpose Although lung volume(LV) can be measured directly by computed tomography (CT), the literature regarding CT-assessed LV in adolescent idiopathic scoliosis(AIS) patients is limited, and the influence of posterior spinal fusionwith instrumentation (PSF) on LV has not been established. This study aimed to identify factors associated with decreased LV after PSF in AIS patients.
