Abstract 【Objective】To explore the correlation between lower back pain and lumbar lordosis angle after lumbar interbody fusion surgery. 【Methods】The clinical data of the 124 cases of the patients who received lumbar interbody fusion surgery from February 2011 February 2011 were respectively analyzed, with 32 cases of patients with low back pain considered the observation group and 92 cases of patients without low back pain considered the control group. The lumbar lordosis angle, lower back pain VAS score, and lumbar dysfunction ODI score of the two groups at the time of the preoperative and postoperative 6 weeks, 3 months, 6 months ,12 months ，24 months and the time of the last followup were observed. The correlation was tested using the Pearson correlation analysis. 【Results】The preoperative lumbar lordosis Cobb Angle, low back pain VAS scores and lumbar dysfunction ODI score of the two groups had no statistical significance differences (P>0.05). The postoperative lumbar lordosis Cobb Angle, low back pain VAS scores and lumbar dysfunction ODI score of the two groups were obviously improved than the preoperative, had statistically significant difference (P<0.05); The postoperative lumbar lordosis Cobb Angle of the control group at the each time node were significantly greater than the observation group,had statistically significant difference (P<0.05); With longer duration of the followup,the lumbar lordosis Cobb Angle of the observation group showed a trend of gradually reducing , the low back pain VAS scores and lumbar dysfunction ODI score showed a trend of gradually rising; The three indicators of the observation group after 1 year, 2 years and at the last followup had statistically significant differences with the 6 weeks after surgery (P<0.05);Pearson correlation analysis results show that : the low back pain VAS scores, lumbar dysfunction ODI score of observation group had linear correlation with lumbar lordosis Cobb Angle,show a negative correlation (r=0.702, 0.682,P< 0.05). 【Conclusion】The postoperative low back pain and lumbar dysfunction of the patients with degenerative diseases who received interbody fusion surgery was associated with the lumbar lordosis angle lost, should try to rectify lumbar lordosis Angle.
