Comparison of Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS-TLIF) and PLIF for Lumber Degenerative Disc Disease and Results of Final Clinical Outcomes

A retrospective study was performed involving a total of 96 patients with degenerative lumber spine disease to analyze the MIS-TLIF and PLIF for degenerative disc disease. Method-I: MISTLIF (N=37) and method-II: PLIF (N=59) were used. Pre and postoperative visual analog scores for back and leg pain, Oswestry disability index, and short form-36 scale were compared. Excellent clinical outcomes were obtained in 91 out of 96 patients at 15 months of follow-up in each group. Relatively more incision site, blood loss, and hospital stay period was seen in the PLIF group (P>0.05) and the latter was greater in the MIS-TLIF group, there were fewer incision site, less blood loss and hospital stay (P<0.05). The few surgical outcomes that were found to be statistically significant between MIS-TLIF and PLIF, did not affect the overall outcomes. However, MIS-TLIF may have better outcomes. The final clinical and neurological results were similar and satisfactory in both MIS-TLIF and PLIF groups
