Abstract：Objective To compare clinical result of minimally invasive transforaminal lumbar interbody fusion(TLIF) and open TLIF through Wiltse approach and conventional approach in treatment of degenerative lumbar disease.Methods Thirty-six and 46 patients of Wuxi People′s Hospital who underwent minimally invasive TLIF (MIS-TLIF) through Wiltse approach and TLIF through conventional approach separately were selected. The operating time, blood loss, creatine kinase, the leaving bed time, postoperative complications, and intervertebral fusion rate were recorded. The function of lumbar and legs was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI). The operating time, blood loss, creatine kinase, the leaving bed time, postoperative complications, intervertebral fusion rate were compared between MIS-TLIF group and TLIF group. VAS and ODI were compared between MIS-TLIF group and TLIF group pre- and post-operatively.Results The operating time, blood loss, postoperative creatine kinase (3 days), the leaving bed time in the MIS-TLIF group were significantly less than those in the group of TLIF(all P values<0.01) . The rate of complication and intervertebral fusion at 1 year between two groups wasn′t significantly different (all P values>0.05). VAS and ODI of 1 year were significantly lower than preoperative in both groups (all P values<0.01), however, there were no significant differences neither at preoperative or final follow-up between groups (all P values>0.05).Conclusions MIS-TLIF is an effective way to treat degenerative lumbar disease. It can reduce the operation wound, hemorrhage during operation and promote early rehabilitation of patients.
