Abstract：Objective To explore the recent clinical efficacy of Wiltse approach and minimally invasive transforaminal lumbar interbody fusion for the treatment of lumbar spondylolisthesis.Methods A total of 46 patients with lumbar spondylolisthesis which Meyerding grade were Ⅰ-Ⅱ degree between May 2015 to May 2016 in authors' hospital were assigned to Wiltse approach and minimally invasive group (n =21) and open group (n =25),including 24 males and 22 females,aged 25 to 78 years [(54.1 ± 10.2) years].And the courses of disease were 3 to 48 months.The differences of the operation time,intraoperative blood loss,intraoperative radiation exposure time and hospital stay were compared.The visual analogue scale (VAS),Oswestry disability index (ODD and the slip angle,slip rate,intervertebral height and other indicators were used to assess the efficacy of before and after 3 days,3 months and 1 year treatment.Results All 46 patients were followed up for 12-24 months,with an average of (18.3 ± 9.2) months.There was no significant difference in the operation time between two groups(P＜0.05).The intraoperative blood loss and hospital stay in minimally invasive group were significantly lower than those in the open group (P＜0.05).The intraoperative radiation exposure time in the open group was lower than that in the minimally invasive group (P＜0.05).The VAS and ODI scores of two groups were significantly different at various postoperative time points when compared with the preoperation (P ＜ 0.05).The VAS score of lumbago in 3 days after operation was significantly lower in minimally invasive group than that in open group (P＜0.05).The slip angles,slip rates and intervertebral height results of two groups were significantly different between preoperation and postoperation (P＜ 0.05),but no significant difference between two groups.Conclusion The recent efficacy of Wiltse approach and minimally invasive transforaminal lumbar interbody fusion for the treatment of lumbar spondylolisthesis is significant,and it has less trauma and faster postoperative recovery.
