The objective of the study was to compare standard manual X-ray measurements of vertebral deformities and values obtained from the Ortelius 800. 52 Patients (41 females and 11 males: mean age 20.35 years) with adolescent vertebral deformities, was studied. The patients were evaluated with standard radiographic views and the Ortelius 800. The parameters considered for the comparison were the angles of scoliosis and kyphosis and the values of global axial deformity, shoulder asymmetry and pelvic tilt. We also evaluated the modification of pelvic/shoulder angle after surgery (this parameter allows to evaluate vertebral rotation and can be derived only from the Ortelius 800). This study allowed us to conclude that there is a perfect agreement between measurements with the Ortelius 800 and those resulting from standard x-rays. The system has also proved to have the capability of quantifying changes in vertebral rotation.
该研究的目的是比较椎体畸形的标准手动X射线测量值与从奥特柳斯800获得的值。对52例患有青少年椎体畸形的患者（41名女性和11名男性，平均年龄20.35岁）进行了研究。采用标准X线片和奥特柳斯800对患者进行评估。用于比较的参数包括脊柱侧弯和后凸角度以及整体轴向畸形、肩部不对称和骨盆倾斜值。我们还评估了手术后骨盆/肩部角度的变化（该参数可用于评估椎体旋转，且只能从奥特柳斯800获得）。这项研究使我们得出结论，奥特柳斯800的测量值与标准X射线测量值完全一致。该系统还证明有能力量化椎体旋转的变化。
