Minimally invasive transforaminal interbody fusion for high-grade spondylolisthesis: a retrospective study analysis of a tailor-made solution.
Article in Asian spine journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
STUDY
designRetrospective study. PURPOSE: We investigated cantilever reduction and fusion technique in high-grade spondylolisthesis (HGS) with minimally invasive surgery-transforaminal interbody fusion (MIS-TLIF). OVERVIEW OF LITERATURE: Most publications that describe minimally invasive surgeries for HGS, especially grade 4 or 5 listhesis, utilized a combined anterior and posterior approach. To the best of our knowledge, a detailed report that provides specific technical nuances for optimal use of a posterior-only approach utilizing MIS-TLIF is greatly lacking.
methodsThis study included 36 patients with HGS in whom reduction, posterior instrumentation, and fusion were achieved with MIS- TLIF. They were evaluated for lower back pain and radicular pain, scaled by Visual Analog Scale (VAS) score. Erect radiographs were performed to calculate slip angle (SA) and sacropelvic and spinopelvic parameters preoperatively, postoperatively, and at each follow-up until 4 years.
resultsThis study identified 30 patients with grade III HGS and six patients with grade IV/V HGS. Spinopelvic parameters were unbalanced in 13 patients. Complete reduction was achieved in 24 patients, with end-stage reduction of grade I with adequate spinopelvic balance achieved in 12 patients. Intraoperative neuromonitoring demonstrated no loss of signals throughout the procedure in any of the patients. Excellent functional outcome was achieved with back pain as well as leg pain VAS score improvements postoperatively in all patients. No implant-related complications or pseudoarthrosis incidences were reported at long-term follow-up at 4 years.
conclusionsMIS-TLIF for HGS is a specific solution for a complex pathology, enabling one to achieve an excellent clinical as well as radiological outcome.
