摘要
动力性固定系统在治疗腰椎退行性病变引起的下腰痛中起着重要的作用。短节段的腰椎融合不会对腰椎的整体活动度有太大的影响,但是保留运动节段的灵活性就可防止邻近节段的退变,即使在小关节需要切除的情况下,也可为椎间盘置换留下机会,甚至在腰椎融合方面仍具有重要作用。动力性固定系统能够在维持腰椎正常活动范围的同时,通过在相应运动节段内减低椎间盘负荷,为椎间盘及其他软组织的恢复提供一个良好的环境,并能够延缓小关节退变的发生,重建脊柱的生物力学功能。
Dynamic stabilization system plays an important role in the treatment of the degenerative lumbar spine. Fusion of short movement segments has little influences on the motion of lumbar spine, Meanwhile,preservation of movements of segment can prevent the degeneration of adjacent segment and maintain the possibility of disc replacement even under the condition that facet joints need to be excised. While maintaining the normal lumbar motion,dynamic stabilization system can not only decrease the load of intervertebral disc of corresponding movement segments and provide a good environment for the recovery of intervertebral disc and soft tissues, but also delay the degeneration of small facet and reconstruct the biomechanical function of spine.
