1° case. a) At age 14 years and 11 months, the final distraction of the Magec rods was reached; the radiologic image shows a right thoracic curve of 50° and a left lumbar curve of 40° (Risser 5). b) Five months after removal of Magec rods, the radiologic image shows the curves worsening, with a right thoracic curve of 61° and a left lumbar curve of 57°. c) The radiologic image shows an instrumented fusion T4 to L4 with a right thoracic curve of 21° and left lumbar curve of 23°. d) The clinical image shows the excellent final results.

2° case. a) At age 15 years and 10 months, the final distraction of the Magec rods was reached; the radiologic image shows a right thoracic curve of 38° (Risser 5). b) Ten months after removal of the Magec rods, the radiologic image shows the curve's evolution, with a right thoracic curve of 72°. c) The radiologic image shows an instrumented fusion T5 to L2 with a right thoracic curve of 43° and right thoracoplasty (6°–11° ribs). d) The clinical image shows the good final results.

2° case. a) The clinical image, at 10 months after removal of Magec rods, shows the clear worsening, with an unbalanced trunk and shoulders. b) The clinical image, at 10 months after removal of Magec rods, points out a severe ribs hump (Adams test). c) The intraoperative picture, during the final instrumented fusion, shows an arthrodesis (blue arrow) on the convexity side of the thoracic curve, a sign of spontaneous autofusion.
