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 investigate whether the sagittal morphology differs between the left and right thoracic curves in patients with Chiari malformation-associated scoliosis (CMS). ⋯ Significant differences in sagittal profiles indeed exist between CMS patients and healthy adolescents, as well as between CMS patients with different curve directions. In CMI patients with a left thoracic curve, compensatory alterations appear to occur in LL in response to the increased TK to maintain a balanced posture.

The aim of this study is to determine the contribution of thrombospondin 2 (THBS2) polymorphisms to the development and progression of lumbar spinal stenosis (LSS) in the Korean population. ⋯ Although no SNPs in THBS2 were associated with LSS, haplotypes (HAP4 and HAP5) were significantly associated with progression of LSS in the Korean population, whereas another haplotype (HAP1) may play a protective role against LSS development.

We present the results of a prospective series of 60 patients treated for neuromuscular spinal deformities with an original spinopelvic construct using two sacral screws and two iliac screws. Clinical and radiological results obtained with this new surgical technique were studied and discussed according to the epidemiological data and relevant literature. ⋯ Despite a high rate of infectious complications, optimal correction of pelvic obliquity requires extension of spinal instrumentation to the pelvis. Spinopelvic fixation remains a difficult challenge in neurological patients with hypotrophy. We think that pelvic fixation with the "T construct" did provide effective and improved spinal stabilization in these patients, while reducing the need for a postoperative cast or brace. As a result, patients had a favourable postoperative course with early mobilization and return to a comfortable sitting position.

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.
