Adjacent segment degeneration (ASD) is a relatively common phenomenon after spinal fusion surgery. Whether ASD is a consequence of the previous fusion or an individual's predisposition to continued degeneration remains unsolved to date. This article summarizes the existing biomechanical and clinical literature on the causes and clinical impact of ASD, as well as possible risk factors. Further, the theoretical advantage of motion-preserving technologies that aim to preserve the adjacent segment is discussed.
相邻节段退变（ASD）是脊柱融合手术后一种相对常见的现象。ASD是先前融合手术的结果还是个体持续退变的易感性，至今仍未得到解决。本文总结了关于ASD的病因、临床影响以及可能的风险因素的现有生物力学和临床文献。此外，还讨论了旨在保留相邻节段的保留运动技术的理论优势。
