5 and spinal intrusion ratio (SIr, r = -0.50 and -0.45). The kyphosis-lordosis index (KLi) correlated with FEV /FVC (r = 0.29). Multivariate regression analysis of coronal and sagittal Cobb angles produced a model which explained 35% and 30% of the variance in FEV and FVC, whilst a regression model consisting of AVBRr and SIr was able to predict 54% and 48%. AVBRr , RHDi and SIr measured on posterior-anterior and lateral radiographs provide better estimations of lung function in preoperative AIS patients than Cobb meas
