Abstract：Objective To compare the clinical efficacy of transforaminal lumbar interbody fusion via Quad-rant minimally invasive system ( mini-TLIF ) versus traditional open transforaminal lumbar interbody fusion ( open-TILF) in the lumbar spine spondylolisthesis .Methods This was a retrospective review of collected data .Between January 2010 and January 2012 ,40 patients with low-grade spondylolisthesis were operated in our hospital ,20 patients underwent open-TILF and 20 patients underwent mini-TLIF.The blood loss, length of cut,operating time,postopera-tive bedrid time in the two groups were recorded perioperatively .Pain and functional disability were measured using visual analogue scale(VAS) and oswestry disability index(ODI) before operation,at 2 weeks,2 months,1 year and 2 years after operation .The therapeutic effects were compared between two groups after operations .Results In aspect of the blood loss,length of cut,postoperative bedrid time,the mini-TLIF group was better(P<0.01),while the open-TILF group was better in the operating time ( P<0.05 ) .Postoperative VAS and ODI scores in two groups were decli-ning after operation ,each point scores were statistically significant difference ( P<0.01 ) compared with preoperative scores.The postoperative VAS and ODI scores in mini-TLIF group decreased more markedly than those in the open-TILF group,the difference was statistically significant (P<0.01).The scores of VAS and ODI of mini-TLIF group were less than those in open-TILF group at 2 weeks and 2 months after operation ( P<0.01 ) .Conclusion The trans-foraminal lumbar interbody fusion operation by Quadrant system to treat the patients with lumbar spondylolisthesis is more simple and efficient than open TILF .It has advantages in the blood loss , length of cut , postoperative bedrid time and the short-term postoperative pain .Provided strictly master the operation indications ,it is worth to be promoted .
