【摘要】：目的利用MRI影像探讨腰椎管狭窄症(LSS)患者椎间盘退变与硬膜囊横截断面积(DSCA)的关系。方法抽取91例中央型退行性腰椎管狭窄症患者作为LSS组,同时选取91例健康者作为对照组,利用MRI测量腰椎间盘退变和DSCA,根据Pfirrmann方法将椎间盘退变分为5级。结果 LSS组的椎间盘退变和年龄无相关性;两组的下腰椎重度退变椎间盘比例均高于L2/3节段,在L4/5、L5/S1节段的重度退变椎间盘比例,LSS组均比对照组高(P0.05);重度退变椎间盘组和轻度退变椎间盘组的DSCA比较,LSS组仅在L2/3、L3/4差异有统计学意义,对照组在各节段无统计学差异。结论腰椎管狭窄症患者在L4/5、L5/S1节段椎间盘退变比正常人更严重,硬膜囊横截断面积和椎间盘退变无相关性,在L2/3、L3/4节段硬膜囊横截断面积随椎间盘退变严重而变小。
[Abstract]:Objective to investigate the use of MRI images of lumbar spinal stenosis (LSS) patients with intervertebral disc degeneration and the dural sac cross sectional area (DSCA). The relationship between the extraction method of 91 cases of central type of degenerative lumbar spinal stenosis patients as LSS group, and 91 healthy subjects were selected as control group, using MRI measurement of lumbar disc degeneration and DSCA, according to the Pfirrmann method of intervertebral disc degeneration is divided into 5 levels. The LSS group of intervertebral disc degeneration and age had no correlation; two groups of severe lower lumbar intervertebral disc degeneration were higher than the proportion of L2/3 segment, L5/S1 segment in L4/5, severe degeneration of the intervertebral disc ratio in LSS group was higher than that in control group (P0.05); severe intervertebral disc degeneration of intervertebral disc degeneration group and mild group DSCA, group LSS only in L2/3, there were significant differences in L3/4, the control group in each segment of the difference was not statistically significant. Conclusion patients with lumbar spinal stenosis in L4/5 L5/S1 intervertebral disc more than normal There was no correlation between the area of the transverse truncation of the dural sac and the degeneration of intervertebral disc. At L2/3, the intertruncated area of the dural sac in the L3/4 segment became smaller with the degeneration of the intervertebral disc.
