摘要
目的 :观察颈椎后纵韧带在脊髓型颈椎病中对脊髓的压迫作用。方法 :在 8例颈前路减压患者术中 ,先纵向切除一半的后纵韧带 ,观察切除后纵韧带侧及未切除后纵韧带侧硬膜囊的形态及刮除骨赘后后纵韧带的漂浮状况 ,最后完全切除后纵韧带。结果 :后纵韧带切除侧硬膜囊向前膨出形态恢复良好。未切除后纵韧带侧 ,硬膜囊均不同程度受后纵韧带的压迫 ,刮除椎体上下缘骨赘后后纵韧带向前的漂浮有限 ,不足以很好地恢复硬膜囊的形态。完全切除后纵韧带后 ,硬膜囊形态恢复良好。结论 :颈椎退变增生的后纵韧带是脊髓型颈椎病中脊髓致压的重要因素之一 ;切骨减压后后纵韧带向前漂浮有限 ,不能使脊髓彻底减压
Objective:To observe the compression of the posterior longitudinal ligament(PLL)on the spinal cord in cervical spondylotic myelopathy(CSM) Method:In 8 cases with the anterior cervical operation,one half of the PLL were resected longitudinally The shape of the dura sac were observed on the removed and unremoved the PLL side The effect of the “flow” of the PLL were observed after removal of the posterior osteophyte of the vertebral body Lastly,complete resection of the PLL were done Result:The shape of the dura sac recoverd very well in the side of removing the PLL,but at the side of unremoved the PLL,the dura sac was still compressed by the PLL After removal of the posterior osteophyte of the lower and upper edge of the vertebral body,The result of the “flow” of the PLL was not significant Conclusion:The degenerated PLL is an important factor that the spinal cord to be compressed in CSM The complete decompression of the spinal cord can not be obtained by the “flow” of the PLL The degenerated PLL must be resected in the anterior cervical operation of CSM
