Comparative Study between Posterior Lumbar Interbody Fusion (FLIF) and Transforaminal Interbody Fusion (TLIF) in the Treatment of Spondylolisthesis

Abstract

Objective: In this study our main goal is to compare the efficiency of posterior lumbar interbody fusion (FLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of spondylolisthesis. Method: This experimental observational type study was carried out at Bangabandhu Sheikh Mujib Medical University and different private hospital in Dhaka from July, 2006 to December 2019. A total number of 340(PLIF=150, TLIF=190) patients underwent lumbar interbody fusion with pedicle screw fixation for the treatment of adult lumbar spondylolisthesis were taken as a study sample. Results: During the study, surgical outcomes between PLIF and TLIF where there were significant differences between the groups in relation to VAS for back pain. These variables were significantly higher in the TLIF group compared to the PLIF group. There was no significant difference between the two groups with respect to VAS for leg pain at final follow-up. However prevalence of Nerve Root injury,Dural tearand blood loss is higher in FLIF groupe than TLIF group. Also, at the time of the last follow-up, both groups had similar slip reduction, and spinal fusion rates (P > .05). Conclusion: From our study we can say that, TLIF is superior to PLIF with respect to functional outcome and complication rate in grade I/II single-level lumbar spondylolisthesis.
