Patient description: The patient was a 10-year-old female, 129-cm tall, weighing 30 kg, and menarche had occurred three months earlier (Fig. 1).
Preoperative radiograph. X-ray imaging showed kyphosis of 84  between T6 and L3 with T12 as the apical vertebra and kyphosis was corrected to 38  under traction. Local kyphosis was 51  between T11 and L1 with slight scoliosis in anteroposterior view.

L3, with T12 as the apical vertebra, and kyphosis was corrected to 38  under manual traction. Local kyphosis was 51  between T11 and L1 with slight scoliosis in the anteroposterior view (Fig. 2).
(a) Computed tomography myelogram. (b) Magnetic resonance imaging. Anterior vertebral wedging was recognized between T11 and L1, with T12 as its center but without any apparent vertebral compression fractures. The patient did not have spinal canal stenosis eitherr.

Computed tomography and magnetic resonance imaging revealed anterior vertebral wedging between T11 and L1 without any apparent compression fractures (Fig. 3a, b).
(a) Postoperative radiograph. Kyphosis was corrected from 84  to 35  between T6 and L3. Local kyphosis improved from 51  to 16 . Lumbar lordosis decreased from 26  to 6 . (b) Final follow-up radiograph (6 years after surgery). The kyphosis was maintained at 39  without vertebral fracture at the latest follow-up. (c) Final follow-up computed tomography (6 years after surgery). T12 pedicle subtraction osteotomy was performed, and the thoracolumbar junction became flat.

L3 (Fig. 4a). Local kyphosis improved from 51  to 16  between T11 and L1. No vertebral fractures had occurred at the time of last follow-up (Fig. 4b).
