Cotrel-Dubousset Instrumentation (CDI) presents a diversified posterior implant system applicable in any situation requiring posterior spinal instrumentation. It acts in the three dimensions of the spine, frontal-sagittal-axial. Correct hook site selection and direction provide spinal balance in three dimensions. The double major idiopathic scoliosis is an appropriate model on which to learn the principles of usage of CDI Results of CDI in a wide variety of spinal pathology have been excellent. There is a learning curve for CDI, hook placement being the most significant. Pitfalls and complications can be avoided.
Cotrel-Dubousset内固定系统（CDI）是一种多样化的后路植入系统，适用于任何需要后路脊柱内固定的情况。它在脊柱的三个维度，即额状面、矢状面和轴状面发挥作用。正确选择钩的置入部位和方向可在三个维度上实现脊柱平衡。双主型特发性脊柱侧凸是学习CDI使用原则的合适模型。CDI在多种脊柱病变中的治疗效果极佳。使用CDI存在学习曲线，其中钩的放置最为关键。可以避免陷阱和并发症。
