Correction manoeuvres are as important as the other issues such as hardware selection, graft options, fusion and osteotomy techniques in the surgical treatment of spinal deformities.The property of materials demonstrating both viscous and elastic characteristics when undergoing deformation is called visco-elasticity. Purely elastic materials change in shape with a stress, and go back to their initial form when the stress is removed. However, visco-elastic materials, like the spine, may protect their new formation unless a back stress is applied. Time is a very important parameter during manoeuvre application to the spine because of its visco-elastic behavior.The most common correction manoeuvres that can be used for spinal deformities are rod de-rotation, distraction-compression, rod bending, segmental de-rotation, de-rotation and cantilever.Spontaneous correction of a minor curve is possible after selective fusion of a major curve due to coupling phenomenon.

在脊柱畸形的外科治疗中，矫正手法与硬件选择、植骨选择、融合和截骨技术等其他问题同样重要。材料在变形时表现出粘性和弹性特征的特性称为粘弹性。纯弹性材料在受力时会改变形状，并在去除应力后恢复到初始形状。然而，像脊柱这样的粘弹性材料，除非施加反向应力，否则可能会保持其新形成的形状。由于脊柱的粘弹性行为，时间在对脊柱施加手法时是一个非常重要的参数。可用于脊柱畸形的最常见矫正手法是棒旋转、撑开-压缩、棒弯曲、节段旋转、旋转和悬臂。由于耦合现象，在对主弯进行选择性融合后，小弯有可能自发矫正。引用本文：2017；2。DOI：10.1302/2058-5241.2.170002。最初在线发表于www.efortopenreviews.org。
