Method: The study was approved by the local ethics committee, and a written consent was obtained for each subject. The study included 40 patients divided into 2 groups (A and B), group A included 20 patients and it was treated by transforaminal lumbar inter body fusion (TLIF) while group B included 20 patients and it was treated by Posterolateral fusion (PLF). Patients were followed for a period of one year.
Results: Functional outcome was assessed using Modified Oswestry Lower Back Pain (LBP) disability questionnaire [ODI Score] system. There was a statistically significant difference between preoperative and one year postoperative ODI (Oswestry Disability Index) score in TLIF group and PLF group (P-value
