Vertebral body tethering (VBT) is an alternative to fusion for selected scoliosis patients. As VBT does not limit spine mobility, it has been propagated that this technique allows a quicker return to physical activity than fusion. However, no data are available to support this statement. Aim of this study was to quantify how much time patients required to resume preoperative activity level and to seek possible associations between return to physical activity and demographic, radiographic and surgical data. ⋯ VBT allows patients to quickly return to their preoperative activity level, irrespectively of the postoperative Cobb angle or type of instrumentation.

To investigate the prevalence of congenital scoliosis (CS) in infants based on chest-abdomen radiographs. ⋯ The prevalence of CS in infants based on chest-abdomen X-rays in the ED was 1.8‰. Both the vertebral and rib anomalies mainly affected the main thoracic region. The spine deformities in infants with concomitant defects of other organs could be identified earlier because of early-onset symptoms, which also bring out a selection bias in our analysis.

The complex three-dimensional spinal deformity in AIS consists of rotated, lordotic apical areas and neutral junctional zones that modify the spine's sagittal profile. Recently, three specific patterns of thoracic sagittal 'malalignment' were described for severe AIS. The aim of this study is to define whether specific patterns of pathological sagittal alignment are already present in mild AIS. ⋯ Pathological sagittal patterns are often already present in curves 10°-20°, whereas those are rare in non-scoliotic adolescents. This suggests that sagittal 'malalignment' patterns are an integral part of the early pathogenesis of AIS.

In skeletally immature patients with adolescent idiopathic scoliosis (AIS), vertebral body tethering (VBT) as a fusionless minimally invasive treatment option has been shown to correct the deformity by growth modulation. This prospective cohort study aimed to present the minimum 2 years' results of double-sided VBT applied to double curves of 13 skeletally immature patients with AIS. ⋯ Double-sided VBT was detected to provide 80% of thoracic (48.2° to 9.7°) and 82% of thoracolumbar-lumbar curve correction (45.3° to 8.2°) as a result of average two years. As being a growth modulating treatment option, double-sided VBT as applied under strict inclusion criteria was shown to be safe and effective for the correction of double curves in skeletally immature patients with AIS, by yielding a gradual, growth-assisted correction of both curves together with the preservation of coronal-sagittal balance without any major complications.
