AIM: To investigate the effect of multilevel transforaminal lumbar interbody fusion (TLIF) procedures in lumbar degenerative spine conditions on the restoration of lumbar lordosis (LL) in patients with short- and long-level fusion, and to examine the associated radiological results. MATERIAL and METHODS: This retrospective study reviewed patients with degenerative spinal diseases who underwent lumbar fusion using a multilevel TLIF procedure. Patients with three or fewer segments involved in fusion were assigned to the shortlevel fusion group and those with more than three segments involved in fusion were assigned to the long-level fusion group. The anteroposterior and lateral spine radiographs of the patients were used to measure LL, distal lumbar lordosis and radiological parameters. RESULTS: The study included 47 patients who met the inclusion criteria, with a mean age of 60.4 ± 12.2 years. The mean follow-up time of our patients was 18.3 ± 11 months. Thirty-five (74.5%) patients were women and 12 (25.5%) were men. Overall, 12 patients underwent 3-level and 35 patients underwent 2-level TLIF. Long-level fusion was performed in 24 patients and short-level fusion was performed in 23 patients. CONCLUSION: Multilevel TLIF can be used to correct spinopelvic alignment when applied with the appropriate indications and techniques in patients with degenerative spinal disorders. Multilevel TLIF is associated with substantial improvements in LL, distal lumbar lordosis, and SVA (sagittal vertical axis). It also helps to correct the correlation between PI and LL
