Eighty-two patients with idiopathic scoliosis were treated by Cotrel-Dubousset instrumentation between 1987 and 1991. Twenty were treated with hooks only, 47 with screws and hooks, and 15 with screws only. The methods were compared and the findings showed that screw fixation can be used in the thoracic spine without neurological complications. The screws provided immediate stability with rigid fixation, together with better correction of frontal, sagittal and rotational deformity. There is less loss of correction, a shorter fusion and less risk of neurological complications because of the placement outside the spinal canal and the rigid fixation in derotation. The technique was simpler and the operating time shorter than with the other methods.
1987年至1991年间，82例特发性脊柱侧凸患者接受了Cotrel-Dubousset器械治疗。其中20例仅使用钩进行治疗，47例使用螺钉和钩，15例仅使用螺钉。对这些方法进行了比较，结果表明，螺钉固定可用于胸椎，且无神经并发症。螺钉通过牢固固定提供即时稳定性，同时能更好地矫正额状面、矢状面和旋转畸形。由于置于椎管外且在去旋转时牢固固定，矫正丢失较少，融合段较短，神经并发症风险较低。该技术比其他方法更简单，手术时间更短。
