Twenty-six patients who underwent Wisconsin instrumentation and 36 patients who underwent Cotrel-Dubousset instrumentation (CDI) for idiopathic scoliosis were studied. Inclusion in the study required at least 24-month follow-up. Variables compared included operating time, blood loss, frontal plane correction, axial and sagittal plane changes, effects on compensation, and complications. In general, operating time, blood loss, and instrumentation problems were greater with CDI. Thoracic curve correction in King II curves was better with CDI. There was no advantage to either system with respect to sagittal plane alignment or rotation. When all factors were considered, a significant advantage to use of CDI could not be demonstrated.
对26例因特发性脊柱侧凸接受威斯康星器械治疗的患者和36例接受 Cotrel-Dubousset 器械治疗（CDI）的患者进行了研究。纳入该研究要求至少随访24个月。比较的变量包括手术时间、失血量、额面矫正、轴向和矢状面变化、对代偿的影响以及并发症。总体而言，CDI的手术时间、失血量和器械问题更多。CDI对King II型曲线的胸段曲线矫正效果更好。在矢状面对齐或旋转方面，两种系统均无优势。综合考虑所有因素后，无法证明使用CDI有显著优势。
