Staged Lateral Lumbar Interbody Fusion Targeting Driver and Compensatory Structural Segments for Adult Degenerative Scoliosis: A Novel Strategy and Early Outcomes.
Article in Orthopaedic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTraditional treatments for adult degenerative scoliosis (ADS) often rely on highly morbid long-segment fusions. While lateral lumbar interbody fusion (LLIF) provides a minimally invasive alternative, consensus on precise surgical targets is lacking. We propose a novel strategy targeting "driver" and "compensatory structural" segments to optimize surgical outcomes.
methodsA retrospective review of 104 ADS patients (2023-2024) compared this targeted LLIF strategy (n = 64) to traditional posterior surgery (n = 40). The LLIF approach utilized staged procedures focusing exclusively on segments driving the primary deformity and rigid compensatory segments. We evaluated radiographic parameters and clinical outcomes (VAS, ODI, EQ-5D).
resultsThe LLIF group achieved significant deformity correction, with the coronal major Cobb angle decreasing from 24.73° to 10.76°, alongside marked improvements in sagittal alignment. Patients exhibited progressive self-correction of coronal balance over the 1-year follow-up. Clinical scores (VAS, ODI, EQ-5D) improved significantly. Compared to the traditional group, targeted LLIF resulted in significantly shorter operative times and less blood loss, with comparable overall complication rates (16.0% vs. 20.0%), although traditional surgery achieved superior immediate radiographic correction.
conclusionTargeting driver and compensatory structural segments via LLIF is an effective, minimally invasive strategy for ADS. It offers substantial deformity correction, symptom relief, and progressive postoperative self-correction while significantly reducing surgical trauma compared to traditional long-segment fusions.
