| Objective:To investigate the correlation between nerve root sedimentation and lumbar disc herniation and the role of nerve root sedimentation in predicting the effect of conservative treatment for lumbar disc herniation.Methods:68 patients diagnosed with L4/5 disc herniation at the rehabilitation department of the First Affiliated Hospital,Anhui Medical University between June 2014 and October 2015 were selected, in which 36 cases were divided into A group( Positive group) and 32 cases were into B group(Negative group) according to whether accompanying with nerve root sedimentation. Our work detected whether there were differences between the two groups through comparison of general information(age, sex, duration and the ratio of dural sac compression area), JOA score and VAS score between A and B group. Afterwards, all the patients in the both groups received the same conservative treatment for one month, then whether there was a discrepancy of effect in two groups after treatment was evaluated through collectng the patients JOA score and VAS score once again and calculating the significant efficiency before and after treatment.Result:There was no statistical difference in sex, age and course of disease between the two groups(P>0.05). However, the comparison of the ratio of dural sac compression area between the two groups was significantly different.the dural sac compression degree of patients in group A was universally much severer than that of patients in group B.When the ratio was more than 25%, the number of LDH patients accompanied with positive nerve root sedimentation significantly increased(P<0.05).The discrepancy of VAS score between the two groups neither before treatment nor after one month treatment wasn’t statistically significant(before:t=0.755,P>0.05, after:Z=-0.15,P>0.05),which suggested the VAS score couldn’t be an available indicator of the existing nerve root sedimentation. There was no significant difference in JOA score between the two groups before treatment(t=-0.149,P>0.05),however,the discrepancy of JOA score between the two groups after one month treatment was statistical significance(t=-3.388,P<0.05),however, there was no significant difference in VAS score between the two groups(P>0.05),but the JOA score after treatment in B group was notably higher than that in A group. There was no difference in the effective rate of VAS between the two groups after treatment(x2=0.008, P>0.05); whereas, there was a significant difference in the effective rate of JOA between the two groups after treatment(x2=5.110,P<0.05),in which the effective rate of JOA in B group was better than that in A group.Conclusion:1.Nerve root sedimentation is diagnosed in LDH patients as well. In the 68 patients diagnosed with L4/5 disc herniation in our study,53 percents of the whole patients were nerve root sedimentation positive,47 percents of those were negative;2.There was no significant difference in sex, age and course of disease VAS score and JOA score between positive group and negative group. The more severer of the dural sac compression degree of patients was,the more possibilities of the nerve root sedimentation appeared. While the membrane sac compression area exceed 25%,the rate of the positive nerve root sedimentation in LDH patients increased significantly;3.The effect of conservative treatment for lumbar disc herniation accompanying with nerve root sedimentation is really poorer than that for single lumbar disc herniation, which demonstrated the nerve root sedimentation might be an useful indicator for predicting the effect of conservative treatment for lumbar disc herniation... |
