Abstract: Objective To compare the clinical efficacy of mini-invasive transforaminal lumbar inter-body fusion (MIS-TLIF) through Wiltse approach and traditional approach for the treatment of lumbar spondylolisthesis. Methods A total of 70 patients with lumbar spondylolisthesis were randomly divided group A (n=32) receiving MIS-TLIF through Wiltse approach and group B (n=38) receiving MIS-TLIF through traditional approach. In group A, the affected level was L4/5 in 20 cases and L5/S1 in 12 cases; 9 cases had only low back pain (LBP), while 21 cases had both LBP and leg pain; 17 cases had grade I and 14 cases had grade Ⅱ spondylolisthesis. In group B, the affected level was L4/5 in 22 cases and L5/S1 in 16 cases; 11 cases had only LBP, while 27 cases had both LBP and leg pain; 21 cases had grade I and 17 cases had grade Ⅱ spondylolisthesis. The JOA score, VAS of LBP and leg pain were evaluated 3 months, 6 months and 1 year after surgery. The post-operative dynamic X-rays, CT and/or MR were used for imaging evaluation. Results There was no difference in gender, age, affected levels, degree of spondylolisthesis, pre-operative JOA score, VAS of LBP, and VAS of leg pain between groups A and B (P>0.05). The incision length, blood loss and exposure time of group A were better than those of group B (P<0.05). The post-operative JOA scoresand VAS of LBP and leg pain were significantly improved after surgery in both groups A and B. The VAS of LBP in group A was lower than that of group B on day 1, day 14, and 1 year after surgery (P<0.05). The interbody fusion rate was not significantly different between groups A and B (P>0.05). There were no complications of internal fixation in both groups. Conclusion MIS-TLIF through both Wiltse and traditional approaches can acquire satisfactory clinical efficacy. Mini-invasive TLIF through Wiltse approach can significantly reduce the damage of multifidus and postoperative incidence of chronic LBP.
