摘要
目的：探讨不同类型颈椎后纵韧带骨化症（ＯＰＬＬ）致脊髓压迫的主要因素。方法：将４３例ＯＰＬＬ分为连续型、混合型、节段型、局灶型。根据术前ＣＴＭ片测量ＯＰＬＬ骨化块及退变性软硬突（椎体后缘增生的骨质或突出的椎间盘）各自占据椎管前后径的比例，并记录颈脊髓最小前后径。结果：４３例中ＯＰＬＬ骨化块和退变性软硬突占据椎管前后径超过４０％者各为１８例；所有病例颈脊髓最小前后径均小于６ｍｍ，主要由于骨化块引起脊髓压迫者１８例（４１９％），由退变性软硬突引起者２５例（５８１％）。连续型中骨化块为压迫脊髓的主要因素，而在混合型、节段型和局灶型中退变性软硬突为压迫颈脊髓的主要因素。结论：ＯＰＬＬ类型不同导致脊髓压迫的主要因素也不同。
Objective: To evaluate the reason about
compressive cord in differnt type OPLL. Method: According to Japanese creteria,43 cases of
OPLL were divided into four groups:segmental type 22 cases,continuous type 11 cases,mixed
type 7 cases and local type 3 cases.To measure the anteriorposterior(AP) proportion of ossified
mass or degenertive apophyses and bulge of disc to spinal canal in CT myelography before
operation,to record the minimum AP diameter of spinal cord. Result: (1)Spinal canal
compressed exceed 40% there are 18 cases in OPLL;(2)All cases of minimum AP diameter of
spinal cord less 6mm.Among them,the compressive reason was ossified mass there were 18
case,of degenerative apophyses and due to 25 cases bulge. Conclusion: There are different
reasons in different type of OPLL.The main reason of spinal cord compressing is ossified
mass.Degenerative change is another reason in the others
