The Application of Selective Intersegmental Laminectomy With Irrigation Technology in the Treatment of Spinal Epidural Abscess.
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
objectivesSpinal epidural abscess (SEA) is a life-threatening spinal infection with a pressing need for timely and effective surgical intervention. Conventional surgical approaches for SEA are often accompanied by extensive spinal tissue trauma and impaired spinal stability. This study retrospectively evaluates the efficacy of selective intersegmental laminectomy with irrigation (SILI), aiming to confirm that skip-level laminectomies combined with intraspinal direct irrigation can achieve effective abscess evacuation for SEA.
methodsAfter ethics committee approval and patient consent, the authors studied patients with ≥ 3 affected segments and neurological deficits who had SILI from March 2020 to July 2024. Patients who had conventional continuous multisegmental laminectomy with drainage (CMLD) at the same time were controls. Inflammatory markers (WBC, CRP, ESR) were analyzed. MRI results were used to see changes in abscess volume and dura mater sac area. SILI's effect on neurological function was evaluated with 3, 6, and 12 months following up using JOA score, VAS, and modified MacNab criteria. Parametric tests (paired/independent t-test, repeated-measures ANOVA) were for normal data, nonparametric (Friedman test, Mann-Whitney U test, Chi-square test) for nonnormal and categorical data, with p < 0.05 for significance.
resultsAll procedures were completed successfully without major complications. Significant improvements were observed across all outcome domains: inflammatory markers demonstrated substantial reductions, with WBC count decreasing from 13.44 ± 2.38 to 8.56 ± 2.26 × 10
conclusionsThrough strategic laminectomy site selection, SILI achieves effective evacuation of epidural abscesses via hydrodynamic bidirectional irrigation, enabling sufficient intraspinal debridement. This approach significantly reduces inflammatory markers and improves neurological function postoperatively.
