Abstract:
Objective To explore the effect of surgical treatment of low back pain patients with Modic change or high intensity zone(HIZ) on MRI of the lumbar spine .Methods 32 cases with intervertebral disc herniation underwent posterior lumbar inter-body fusion and 17 cases with lumbar discogenic pain underwent radiofrequency ablation from March 2011 to July 2012 were retro-spectively reviewed .For intervertebral disc herniation patients ,all patients were divided into two groups :groupⅠ (no with Modic changes group)and groupⅡ(with Modic changes group) ,according to the Admission MRI .GroupⅡ was sub-divided intoⅡa(Mod-ic type Ⅰgroup) andⅡb(Modic type Ⅱgroup) .For lumbar discogenic pain patients ,all patients were divided into group A (without HIZ group) and group B(with HIZ group) .The VAS and ODI scales at the preoperative and follow-up were recorded and analyzed . Results The postoperative scores of VAS and ODI of all the patients were improved ,and the difference was statistically significant (P<0 .05) .For intervertebral disc herniation patients ,three groups have no statistically significant difference (P>0 .05) .For lum-bar discogenic pain patients ,the improvement rate of VAS (low backpain) of A was better than that of B ,and the difference was sta-tistically significant(P<0 .05) ,but the differences of VAS (leg pain) and ODI scores weren′t statistically significant (P>0 .05) . Conclusion Posterior lumbar interbody fusion is effective for lumbar disc herniation patients with Modic changes ,and can obtain good clinical effect .For lumbar discogenic pain patients with high intensity zone on MRI ,radiofrequency ablation can cause clinical symptoms get some relief ,but the effect is poor .
