The Study Of Multi-slice Spiral CT In Adolescent Idiopathic Scoliosis

Part I The Study of Multi-slice Spiral CT in Adolescent IdiopathicScoliosis MorphologyBackground:Scoliosis is a three dimension deformity whose degree of Cobb angle is beyond 10° . Idiopathic scoliosis (IS), one of the most common spine deformities in children, is often seen among the adolescents. Not only scoliosis presents appearance deformity, but also influences the development and maturation of the cardiac and pulmonary in children. It can seriously hurt the mentality and body of the young patients for their normal development. So it is a very urgent problem need to be deal with. A number of researches have been done in recent years on IS all over the world. But till now, all the studies about AIS etiology are not affirmed. To find the IS etiology exactly, you must have a detailed knowledge of the spine morphology. Only a limited number of studies accurately evaluating the IS spine are available, and discovered that there is lordosis in the apical region and decreased thoracic kyphosis. It is relative anterior spinal overgrowth further lead to thoracic lordosis or decreased kyphosis. But there isn't a report to accurate measurement the vertebral body and vertebral arch use CT scan for the thoracic and lumbar spine by now. Objective:To investigate the role of multi-planar reformations using multi-slice spiral CT (MSCT) to measurement the vertebra morphology in AIS girls, and compared with age and gender-matched controls in order to affirm the morphology results of abnormal development of the anterior and posterior elements in AIS. Material and Methods:Thoracic and lumbar spine multi-slice spiral CT was undertaken on 52 girls with AIS between the age of 10 and 18 years, and 54 age and gender-matched non-IS controls.
