The Research Of Lumbar Endplate Modic Lumbar Degenerative Changs And Correlation

Objective:To summarize the lumbar endplate Modic changes in the distribution of clinical features.explore the relevance of Modic changes occur with lumbar degenerationMethods:patients with low back pain in Zhuzhou Central Hospital MRI lumbar spine surgeryand conventional X-ray examination of the October1,2013to February1,2014, excluding waist trauma,tumors, inflammation,congenital a clear case of sexual pathology malformations.Of which325cases of outpatient, inpatient surgical patients23cases;179cases of male, female169cases;aged20-84years old,the average age of men44.5years, women average age45.4years.Modic classification criteria based on the assessment of patients with lumbar sagittal MRI data,records or without Modic changes occur,as well as the type of Modic changes, segmental distribution;According tothe root of T2-weightedMRIin patients withlumbar spine, according toPfirrmanndisc degeneration grading score;sagittal or cross-sectional weighted images displayedon the lumbar intervertebral level of the central canal, nerve root canal,lateral recess than the adjacent vertebral levels significantly narrow the gap recorded as lumbar spinal stenosis;Roots in the lumbar spine X line method using Meyerding degree of lumbar spondylolisthesis were graded and recorded;conducted by Farfan measurements intervertebral height measurement, evaluation measure each intervertebral space height.Allimaging data are relatively independent double-blind analysis of two doctors,and Kappatest.Use SPSS18.0statistical software for dataprocessing, using Logisticregression analysis Modic changes occur to explore gender, age.lumbar segment,bulgingdisc,disc hemiation,disc prolapse,intervertebral change, spinal stenosis, spondylolisthesis correlation.Statistics and analysis stage,the onset of segmental Modic changes,in terms of gender and age distribution of the spine and other pathological changes associated with memory,such asbulgingdisc,disc herniation,discprolapse,changes in the intervertebral space, spinal stenosis.spondylolisthesis relationships.The resulting data is used to compare the correlation chi-square test, P<0.05was considered statistically significant.Results:348cases of lumbar intervertebral disc in1740,89cases (including seven cases of surgical patients)(25.5%)139disc (7.9%) occurred near the end plate Modic changes, which I type in19cases(5.4%)23disc(1.3%),typeII68cases (19.5%)114disc(6.5%), III type2cases(O.5%)2intervertebral discs(0.11%).Disc segment L5/S168, L4/540, L3/418, L2/313each occur rates were19.5%,11.4%,5.1%,3.7%.Modic changes, mainly in theL5/Sl, L4/5both segments.(With an on-parametric Wilcoxon test, x2=26.236, P <0.001,statistically significant differences.)By sex:male in cidence rate of26.2%(47/179), the occur rence of females was24.8%(42/169),no statistically significant difference between the two(P=0.768, P> 0.05)Statistics by age group,20-29age group Modic changes which occurred was0%,30-39age group was12.50%,for the40-49age group is19.15%,50-5934.31%,for the age group60-69-year-old.group.was26.39%,70-79age.group.was20.89%,80-89age.groupwas16.67%, with asignificant difference between the age groups(P=0.0127, P<0.05)Modic changes according to different types of disc degeneration in the incidence statistics, Modic change in prominent cases a higher incidence of prolapse(using non-parametric Wilcoxontest, x2=180.263, P<0.001,there are statistically significant Learn the difference.)According to whether the reduced disc height statistics:normal intervertebral height Modic changes incidence of4.01%(54/1346), disc height reduced by Modic changes in incidence of21.5%(85/394), two species difference was not statistically significant x2=153.1254(P<0.001)According to statistics lumbar spinal stenosis.which is no degenerative lumbar spinal stenosis rate was3.63%(51/1403),there are degenerative lumbar spinal stenosis group was13.24%(38/287),two kinds of the difference was statistically significant(P=0.028, P<0.05).Modic changes in accordance with the incidence of lumbar spondylolisthesis varying degrees in statistics, Modic change in the incidence of cases of lumbar spondylolisthesis I°higher(using the non-parametric Wilcoxon test, x2=270.812, P <0.001,there are statistically significant Learn the difference.)Conclusion:The presence of lumbar endplate Modic changes, the most commontype is typeII, I-type second, III typeis most rare,it occurs in theL5/S1segment, followed by theL4/5.Occur with age.lumbar segmentofthe lumbar spine Modic,bulging disc,disc herniation,disc prolapse,intervertebral change, spinal stenosis, spondylolisthesis correlated; Modic changes may be severe lumbar disc degeneration performance.
