Fig. 2.

A 7-year-old boy with hemivertebra between L3 and L4, presenting segmental scoliosis while the compensatory deformities was mild. We performed posterior hemivertebra and instrumentation with monoaxial pedicle screws. The post operative X-ray showed that the correction was excellent. His body height developed from 125 to 177 cm during 76 months follow-up. Although the correction was maintained well, the screws of the upper vertebra migrated downwards. Solid fusion could be noted on the X-ray and CT scan. We removed the implants. The fusion of the posterior elements was confirmed during the surgery. No correction loss was noted on the X-ray, 6 months after implants removal
