| 摘要：对于腰椎退变和不稳的治疗，传统方法是采用后路减压、椎弓根螺钉固定同时行植骨术（僵硬固定）。然而，僵硬固定存在加速周围椎体的退变等缺点。因而，人们逐步把目光投向腰椎弹性固定。最近几年，腰椎弹性固定因具有利于应力分散，防止周围节段退行性变，降低应力遮挡等优点，越来越多地被用于临床。大多数临床资料显示相较于传统坚强固定，弹性固定疗效相当，而固定节段骨萎缩、骨质疏松以及邻近节段退变的发生率显著降低，更利于脊柱生理特性。该文就腰椎弹性固定的发展过程、各种类型弹性固定的工作原理以及临床效果等作一综述。 |

| ABSTRACT: To treat with the degenerative and instability of lumbar vertebra, we used to adopt posterior decompressive inter- laminectomy, pedicle screw fixation and bone graft fusion. However, the rigid fixation can accelerate the degeneration of adjacent seg- ment. So people gradually concentrate on the elastic fixation of lumbar vertebra. In recent years, the elastic fixation of lumbar pedicle screw is widely used in clinical application. The elastic fixation can reduce stress shielding and avoid adjacent segment degeneration. Meanwhile, it contributes to the stress dispersion. Clinical study shows that compared with traditional rigid fixation, the occurrence rate of bone resorption, osteoporosis and adjacent segment degeneration is significant reduced in the fixed segments of the elastic fixation, and more conform to spine's physiological stability, while its curative effect is equal with rigid fixation. The article provides a review on the phylogeny, working principles and clinical effects of the elastic fixation of lumbar vertebra. |
