Figure 2From: A shallow chest correlates with the aortic position in the normal spine: features resembling those observed in structural scoliosis Right thoracic curvature in the normal spine. To evaluate the thoracic side curvature in the normal spine, Cobb’s angles were measured from T5 to T12 using standing chest radiographs. Right-sided curvature was given a positive value. The mean thoracic side curvature was 3.0 ± 3.0 (mean ± SD).Back to article page
