The evaluation of vertebral rotation and torsion in idiopathic scoliosis is important both in treatment and prognosis. Standard radiography may be used to calculate only rotation but computerized tomography (CT) allows for an exact evaluation of both rotation and torsion. However, it is non feasible to use this method routinely. The purpose of this study is to compare the values obtained by CT scanning with those obtained on radiographic examination by the most commonly used methods of measuring rotation. We also evaluated the morphology of the vertebral canal and its relationship with the dural sac. Forty-seven idiopathic scoliotic curves were included in the study. The Perdriolle method of radiographic measurement of vertebral rotation is the one that most accurately reveals the true extent of the deformity. Vertebral torsion occurred early in 92% of the curves examined. Deformity of the vertebral canal was rarely observed, even in sever cases. The dural sac at the dorsal level was always shifted towards the concavity of the curve.
评估特发性脊柱侧凸中的椎体旋转和扭转在治疗和预后方面都很重要。标准放射摄影可能仅用于计算旋转，但计算机断层扫描（CT）能够精确评估旋转和扭转两者。然而，常规使用这种方法是不可行的。本研究的目的是将CT扫描获得的值与通过最常用的测量旋转方法进行放射学检查所获得的值进行比较。我们还评估了椎管的形态及其与硬膜囊的关系。本研究纳入了47条特发性脊柱侧凸曲线。放射学测量椎体旋转的佩德里奥莱方法是最能准确揭示畸形真实程度的方法。在所检查的曲线中，92%的椎体扭转出现较早。即使在严重病例中，椎管畸形也很少被观察到。背侧水平的硬膜囊总是向曲线凹侧移位。
