Abstract：Objective To compare the clinical results between the mini-incision transforaminal lumbar inter-body fusion(mini-incision TLIF) and conventional open approach in treatment of lumbar spondylolisthesis .Methods A total of 100 patients with lumbar spondylolisthesis underwent surgical intervention were retrospectively analyzed ,in-cluding 50 patients with mini-incision TLIF and 50 patients with conventional open opproach .Operation time, intra-operative bleeding , postoperative drainage volume , and hospitalization time were recorded .Pre-and postoperative back pain was assessed by visual analogue scale ( VAS) ,and lumbar function was evaluated by Oswestry disability in-dex(ODI),the clinical results were assessed by Macnab criterion ,and radiologic parameters were compaerd .Results The mean follow-up time was 18 months (ranged,12~24).The group of mini-incision TLIF was superior to the group of conventional open in intra-operative bleeding , operation time , postoperative drainage volume and hospital stay , postoperative VAS ( P<0.01 ) , the ODI in the patients with conventional open approach decreased from ( 85.9 ± 3.9)%before operation to (19.2 ±4.9)%at the final postoperative follow-up.The ODI in the patients with mini-in-cision TLIF decreased from (84.4 ±5.3)%before operation to (7.7 ±1.3)% at the final postoperative follow-up. There was significant difference of the change in ODI between two groups ( P<0.01 ) .Conclusion Compared with conventional approach , mini-incision TLIF meets the concept of minimally invasive surgery in treatment of lumbar spondylolisthesis , avoids wide stripping of the vertebral adjacent tissues ,and has advantages of smaller incision ,shor-ter hospitalization time ,faster posteroperative recovery ,and lower back pain and so no .It has defined clinical efficacy and simple operation ,and is worth popularizing at the basic-level hospitals .
