The effect of direct vertebral rotation on the spine parameters (coronal and sagittal) in adolescent idiopathic scoliosis

BACKGROUND: Idiopathic scoliosis is accompanied by postural alterations, instability of gait, and functional disabilities. The objective was to verify radiographic parameters (coronal sagittal) adolescents with idiopathic (AIS) pre- post-surgery direct vertebral rotation (DVR), associated type 1 osteotomies in all segments (except the most proximal) 2 periapical vertebrae curves. METHODS: A prospective study design employed which 41 AIS were evaluated compared post-surgery. Scoliosis confirmed a spine X-ray exam (Cobb angle). Eight measured: Cobb angles (thoracic proximal distal), segmental kyphosis, total lumbar lordosis, pelvic incidence, sacral slope, tilt. RESULTS: angle averaged 51.3?± 14.9?. Post-surgery, there significant reductions for following measurement parameters: thoracic (p= 0.003); distal 0.001); kyphosis (T5-T12, p= 0.012); (T1-T12, 0.002). These showed effectiveness surgical correction reduce improve kyphosis. values obtained tilt not significantly different CONCLUSION: technique DVR proved be effective coronal sagittal directed at order favor rehabilitation process.
