A 10-year-old girl first presented a with a major scoliotic curve between T5-T11 of 18°, sacral takeoff angle of 7°, 15-mm iliac crest height, and 12-mm femoral head height difference. At that time, she was treated initially by observation (and later by brace). More than 2 years later, b the curve Cobb angle increased to 42°, sacral takeoff angle decreased to 9°, iliac crest height difference decreased to 11 mm, and femoral head height difference decreased to 11 mm. c Pelvis view of lower limb scanogram of the same patient obtained at the time of first examination with leg length discrepancy of 11 mm, right longer than left
