| Outline of Final Research Achievements |
Our researches were aimed to reveal the mechanism of vertebral body deformities in patients with adolescent idiopathic scoliosis (AIS) by in vivo three-dimensional morphometric analysis. The appearance rates of the ossification center in the epiphyseal ring were lower at the concave side than at the convex side, except in the end vertebrae in AIS patients. This difference was more apparent around the apical vertebrae. The wedge deformity of vertebral bodies showed a reshaping potential towards a symmetrical configuration in the region other than end and apex, although no plasticity of the vertebrae was observed in the apical region even in skeletally immature patients with AIS. When compared to the wedging of the vertebral bodies around apical vertebrae in the major curve in neuromuscular scoliosis, which was caused by asymmetric loading, the wedge deformities in both the main and compensatory curves in AIS were more severe than would be expected.
