The paralytic spine without supplementary support is unstable and susceptible to axial collapse. The biomechanical factors responsible for spinal stability should be considered in any treatment regimen for paralytic spines. If posterior fusion is elected as the treatment, kyphosis must be corrected so that the eccentric loading and kyphotic bending moment is very small. When this is done, posterior fusion alone is adequate to give spinal stability and increased function to the individual.
无辅助支撑的麻痹性脊柱不稳定，易发生轴向塌陷。在任何麻痹性脊柱的治疗方案中，都应考虑影响脊柱稳定性的生物力学因素。如果选择后路融合作为治疗方法，必须纠正后凸畸形，以使偏心负荷和后凸弯矩非常小。这样做时，单纯后路融合就足以提供脊柱稳定性并增强个体功能。
