Comparison Of MIS-TLIF And Plif For Lumber Degenerative Disc Disease And Results Of Final Clinical Outcomes

OBJECTIVE: To compare the difference of postoperative clinical outcomes in DDD between posterior interbody fusion and transforaminal interbody fusion.The study aimed to analyse the MIS-TLIF and PLIF for degenerative disc disease.This articles reports technique,clinical outcomes,design and study who underwent either MIS-TLIF AND PLIF.METHODS: We performed a retrospective study involved a total of 96 patients with degenerative lumber spine disease who underwent MIS-TLIF and PLIF from 2012 January to2014 December.We divided in two methods.Method-I: MIS-TLIF(N=37)and method-II:PLIF(N=59).we compared pre and postoperative visual analogue score for back and leg pain,Oswestry disability index,short form-36 scale.We also recorded operation time,blood loss during surgery and hospital stay period and number of fusion segments.RESULTS: Excellent clinical outcomes were obtained in 90 out of 96 patients at 15 months follow up in each groups.There were no significant differences in back and leg VAS,ODI,SF-36,Fusion condition,and complication at 15 months follow up between the two groups(P>0.05).However,relatively more incision site,blood loss and hospital stay period seen in PLIF group(P>0.05)and the latter was greater in the MIS-TLIF group,there were less incision site,less blood loss and hospital stay(P<0.05).CONCLUSION: The few surgical outcomes that were found to be statistically significant between MIS-TLIF and PLIF,but did not affect the overall outcomes.However MIS-TLIF may have better outcomes.In the final clinical and neurological results were similar satisfactory in both MIS-TLIF and PLIF groups.
