The Armstrong procedure combines the use of a conventional Harrington rod in the concavity of a curve, together with a distracting force on the convex side, this force being applied one vertebra lower. Workers have used this procedure in 35 cases. It is concluded that there are three advantages: A better horizontal disposition of the lower vertebra. Greatly diminished stress on the two rods shown by a biomechanical study. Derotation is more easily obtained and the spine is better balanced as a whole, as shown by a three-dimensional study comparing this method and conventional Harrington rodding.
阿姆斯特朗手术是在脊柱弯曲的凹侧使用传统的哈灵顿棒，同时在凸侧施加撑开力，该力作用于下一个椎体。研究人员已将此手术应用于35例病例。得出的结论是，该手术有三个优点：下椎体的水平排列更佳。生物力学研究表明，两根棒上的应力大大降低。三维研究比较了该方法与传统哈灵顿棒固定术，结果表明，更容易实现去旋转，脊柱整体平衡更好。
