Computerized evaluation of the surface measurement of kyphosis and lordosis in idiopathic scoliosis

Hypokyphosis is usually seen in patients with idiopathic scoliosis. The Quantec spinal image system provides an alternative to measuring the sagittal plane surface contour. The Cobb method and Quantec is significantly correlated (p<0.05), however, differences are larger in kyphosis than in lordosis. The advantage of the QSIS is to reduce X-ray exposure.
