Observation of Clinical Curative Effect of Transmultifidus Lumbar Interbody Fusion in the Treat-ment of Lumbar Degenerative Diseases

Abstract：Objective To investigate and analyze the clinical curative effect of transmultifidus lumbar interbody fusion in the treatment of lumbar degenerative diseases. Methods 62 patients with lumbar degenerative diseases who came to our hos-pital from April,2011 to July,2012 were randomly divided into the control group and the experimental group according to the random number method. There were 31 cases in each group. The control group accepted transforaminal lumbar interbody fusion while the experimental group accepted transmultifidus lumbar interbody fusion. The clinical curative effect of the two groups was compared. Results Blood loss and postoperative drainage volume of the experimental group was significantly less than that of the control group(P<0. 05),while the difference of operation time between the two groups was not statistically signifi-cant(P>0. 05). The VAS score in the 3rd day and 2 weeks after the operation,the ODI index in 1st month and 6th month of the experimental group was statistically better than that of the control group(P<0. 05). The difference of fusion rate,slipping angle,intervertebral disc height and taillard index in the 12th month after the operation between the two groups was not statisti-cally significant(P>0. 05). Conclusion Transmultifidus lumbar interbody fusion has a significant effect in treating lumbar degenerative diseases. The approach has less damage during the operation and improves the efficacy of surgery and patients'quality of life. So it is worth promoting.
