Prospective Assessment of Transforaminal Lumbar Interbody Fusion (TLIF) in Spondylolisthesis: A Radiological and Functional Outcome Study in an Indian Population.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSpondylolisthesis is a common spinal condition in which one vertebra slips over another, leading to pain and disability. Transforaminal lumbar interbody fusion (TLIF) has emerged as a surgical option for addressing spondylolisthesis; however, limited research exists, especially in the Indian context, evaluating its radiological and functional outcomes.
objectiveThe study aimed to evaluate the radiological and functional outcomes of TLIF in spondylolisthesis using standardized scoring systems, to evaluate the sagittal balance of the spine radiologically in patients who have undergone TLIF for spondylolisthesis, and to evaluate the correlation between the functional and radiological outcomes after TLIF.
methodsThis prospective observational study included spondylolisthesis patients undergoing TLIF at SRM Medical College Hospital and Research Centre from August 2022 to August 2024. Criteria included Meyerding grade 1-4 spondylolisthesis, single-segment fusion, and willingness for 12-month follow-up.
resultsForty-five patients were included with age 36.6 ± 12.2 years, with 73.3% being female. L4-L5 is the most common level affected in 21 patients (46.7%). Significant improvements were observed in pelvic tilt 19.07 ± 2.05, sacral slope 30.6 ± 4.4, segmental lordosis 18.4 ± 1.4, lumbar lordosis 57.1 ± 1.8, sagittal vertical axis (SVA) 2.5 ± 0.3, Visual Analog Scale for pain 0.4 ± 0.5, and Oswestry Disability Index (ODI) scores 5.23 ± 2.6 postoperatively (p < 0.05). At one-year follow-up, 84.4% of patients had good-to-excellent outcomes, and 44.4% had definitive fusion according to modified Lee criteria. However, there was no correlation between ODI score and grade of listhesis, pelvic incidence (PI), or SVA of the spine (p > 0.05).
conclusionThis study provides valuable insights into the effectiveness of TLIF surgery in addressing spondylolisthesis, both in terms of radiological and functional outcomes. However, there was no correlation between improvement in functional and radiological parameters (PI vs. ODI, SVA vs. ODI). TLIF appears to offer significant improvements in patient well-being and quality of life. These findings contribute to understanding TLIF's suitability as a treatment for spondylolisthesis and can inform clinical practice, ultimately benefiting patients suffering from this condition.
