Ten patients with idiopathic scoliosis were treated with posterior spinal fusion and Cotrel-Dubousset instrumentation. Computed tomographic scans and intraoperative photographs were used to evaluate the derotational effect of the Cotrel-Dubousset instrumentation. The frontal deformity was corrected from an average of 51 degrees to 15 degrees and the kyphosis from 9.5 degrees to 18 degrees. The amount of preoperative vertebral rotation was variable, however, and insignificant postoperative changes were documented in the majority of cases.
10例特发性脊柱侧凸患者接受了后路脊柱融合术及Cotrel-Dubousset器械固定治疗。采用计算机断层扫描和术中照片评估Cotrel-Dubousset器械的去旋转效果。额状面畸形平均从51度矫正至15度，后凸从9.5度矫正至18度。然而，术前椎体旋转程度各不相同，且大多数病例术后变化不明显。
