| Objective: The Study lumbar endplate Modic changes in degenerative lumbar olisthe regularity, to explore lumbar endplate Modic changes, degenerative lumbar olisthe, correlation between the clinical symptoms, provide theory support for the clinical treatment of degenerative lumbar olisthe, improve the effect of clinical treatment..Methods : From 2014.1 to 2014.12 for low back pain or sciatica in my hospital and surgical treatment for the study of patients with lumbar degenerative spondylolisthesis, Counts and records the patient basic information, And all patients underwent standard MRI and lumbar lateral X-ray imaging, To slip out of the vertebral body as object, The lumbar spine MRI midline sagittal T 2 image, use image analysis software Spine Examiner measured respectively at Modic panel Change the size and the maximum Cone area, Modic area and calculate the rate of change(Modic changing area / maximum vertebral area); Shooting standard standing lumbar lateral X-ray, with the system software to measure the distance(AB) edge between vertebral and after slipping lower and lower vertebrae vertebral sagittal diameter(AC), And calculates the degree of spondylolisthesis(Taillard index), Taillard index = AB / AC; Measure and record the pain visual analog scale preoperatively and after 3 months later when the(VAS) and Oswestry Disability Index(ODI), And according to the following formula, VAS scores improved ratio =(VAS score-postoperative VAS scores before surgery)/VAS score x100%,ODI = improved rate before surgery(preoperative postoperative ODI ODI score-score)/ODI score x100% before operation, Comparative analysis between the lumbar endplate Modic changes and sliding out of relationship compared with Modic changes seen rate Taillard index and correlation between VAS and ODI score before surgery; And evaluate Modic changes Modic array and clinical effects in the changes group, analysis endplate Modic size percentage change and the relationship between the degree of spondylolisthesis symptoms and clinical and curative effect of Modic changes.Results: A total of 52 patients, including 15 men, 37 women, average age of 55.48, L3/4 detachment 2, 3.8%,L4/5 detachment in 44 cases the incidence, incidence 84.6%,L5-S1 detachment in 6 cases, the incidence of 11.5%;Modic in 31 cases, non-Modic 21 cases, incidence of Modic changes type 59.6%;modic1 in 13 cases, the incidence of 17.3%;modic2-15, the incidence of 19.2% Modic3 type 3 cases, the incidence of 9.5%., Occurred lumbar Modic change of section segment for L3/4 1 cases; L4/5 26 cases; L5/S1 4 cases, L4/5 is lumbar back degeneration sliding de good sent parts, is lumbar Modic change most often occurred section segment, sliding de stage and non-sliding de stage Modic change occurred rate differences has statistics meaning(P<0.05); Modic area change rate and Taillard index obviously related(P<0.05), has statistics meaning; Modic area change rate associated with VAS and ODI score before surgery(P<0.05), a statistically significant; Modic changes Modic array with improved rates were significantly different in the change group(P<0.05).Conclusions :1 The lumbar vertebra lamina terminalis Modic change is drawing back the denatured lumbar vertebra to slide to hit the disease incidence rate to be high, mainly occurs in the Watt stage.2 lumbar endplate Modic changes in area ratio was positively correlated with the size and extent of degenerative lumbar spondylolisthesis3 Lumbar endplate Modic changes in the ratio of the size of the area was positively correlated with the clinical symptoms.4 PLIF is an effective method for the treatment of degenerative spondylolisthesis, but the end plate Modic changes were associated with postoperative recovery effect than did those poor end plate Modic changes. |
