The authors present 15 cases of congenital scoliosis with lumbar or thoracolumbar hemivertebra in children under 10 years of age (mean age at the time of surgery was 5.5 years). Patients were treated by posterior hemivertebra resection and pedicle screws two levels stabilization or three or more levels stabilization in the case of deformity above or under hemivertebra or for severe curve deformities. ⋯ Surgery should be considered as soon as possible in order to avoid severe deformity and the use of long segment arthrodesis. The youngest patient we treated, with a completed dossier at the end the follow up was 24 months old at the time of surgery; the youngest patient treated by this procedure was 18 months old at the time of surgery.

To determine the risk factors of neurologic deficits during PVCR correction, so as to help improve safety during and after surgery. ⋯ Preexisting neurologic dysfunction, associated with intraspinal and brain stem anomalies, scoliosis associated with thoracic hyperkyphosis and level of vertebral column resected are independent risk factors for neurologic deficits during PVCR procedure.

This study aimed at deriving a lordosis predictive equation using the pelvic incidence and to establish a simple prediction method of lumbar lordosis for planning lumbar corrective surgery in Asians. ⋯ This simple calculation method can provide a more appropriate and simpler prediction of lumbar lordosis for Asian populations. The prediction of lumbar lordosis should be used as a reference for surgeons planning to restore the lumbar lordosis in lumbar corrective surgery.
