Background and Objective; Degenerative spondylolisthesis is surgically treated by various techniques; transforaminal lumbar interbody fusion (TLIF) and posterolateral fusion (PLF) are two of the most common techniques used in surgery. In our study we describe our experience in these techniques in treating degenrartive spondylolisthesis regarding outcome and complications. Methods; This prospective study was conducted upon 32 patients with degenerative spondylolisthesis, divided in 2 groups randomly selected; one group will be operated upon by posterolateral fixation and the other group by TLIF at the Department of Neurosurgery, Cairo University KasrAlainy. We evaluated surgical outcomes in terms of clinical improvement, degree of lumbar lordosis correction and complications. Results; Thirty-two patients were included in this series; divided in two groups. Postoperative mean visual assessment score (VAS) in TLIF group was 1.5 regarding leg pain and 2.75 regarding back pain, while in the PLF group was 1.56 regarding leg pain while 2.87 regarding back pain. Degree of correction in the TLIF group was (2.06 - 33.36 with mean 8.74 ± 9.06), while in the PLF group was (-15.86{u2013}25.3 with mean 4.06 ± 8.8). 28 patients (87.5%) had no complications, 1 patient (3.12%) needed reoperation and screw revision, 2 patients (6.25%) suffered from weaknessand 1 patient (3.12%) suffered from superficial wound infection. Conclusion;our study shows no statistical significant difference in the clinical outcome in both groups regarding back and leg pain and regarding correction of lumbar lordosis with improvement of global sagittal balance
