Fig. 5From: Contribution of coronal vertebral and IVD wedging to Cobb angle changes in adolescent idiopathic scoliosis during growthRelatively more vertebral wedging in the thoracic curve and more IVD wedging in the lumbar curve. a In the thoracic curve (T1-T6), a pattern of wedging was observed in the vertebral wedging for all visits but not in IVD wedging. The average sum of vertebral wedging was 14.1° while that of IVD wedging was 6.0°. b In the lumbar curve (T12-L4), a pattern of wedging was observed in IVD wedging for all visits but not in vertebral wedging. The average sum of vertebral wedging was 9.2° while that of IVD wedging was 16.4°Back to article page
