Progressed curves. a X-ray at the first clinical visit. T7/L1 = 24.3°. L1/L4 = 16.7°. b X-ray of the latest clinical visit. T7/L1 = 60°. L1/L5 = 37.6°. c Vertebral wedging of the thoracic curve. At the early stage of scoliosis, the wedging increased from T9 to T10 and then decreased to T11. The wedging increased from T8 to T10 and then decreased to T12. The wedging at the apex (T10) increased from 4.4° at the first clinical visit to 17.0° at the latest visit. d IVD wedging of the lumbar curve. The wedging at the apex (L2/L3) increased gradually from 5.4° at the first clinical visit to 10.0° at the latest visit. e Summation of the wedging value of the thoracic curve. Given that a gradual increase in wedging was found in vertebral wedging, the sum of the vertebral wedging was from 13.1° to 44.4°. f Summation of the wedging value of the lumbar curve. Given that a gradual increase in wedging was found in IVD wedging, the sum of the IVD wedging was from 17.3° to 28.4°
