Interlaminar Contralateral Endoscopic Foraminotomy Reduces Postoperative Dysesthesia in Patients With Degenerative Lumbar Deformity: A Multicenter Comparative Cohort Study.
Article in Global spine journal, 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
Study DesignRetrospective-prospective multicenter comparative cohort study.ObjectivesPostoperative dysesthesia (POD) is a recognized complication of transforaminal endoscopic lumbar surgery, with reported rates up to 21.5%. Degenerative lumbar deformity may amplify this risk through vertebral rotation displacing the dorsal root ganglion into the transforaminal trajectory. This study compares POD rates and functional outcomes between transforaminal endoscopic lumbar foraminotomy (TELF) and interlaminar contralateral endoscopic lumbar foraminotomy (ICELF) in degenerative lumbar deformity, and explores vertebral rotation as a mechanistic basis for approach selection.MethodsOne hundred patients with degenerative lumbar deformity (Cobb ≥10°) and foraminal stenosis underwent single-level endoscopic foraminotomy across 6 centers in Latin America: a retrospective cohort of 46 patients treated with TELF (2021-2023) and a prospective cohort of 54 patients treated with ICELF (2023-2025). Vertebral rotation was measured by CT using the Aaro-Dahlbornmethod. Primary outcome was POD occurrence; secondary outcomes included VAS, ODI, and modified MacNab criteria at 12 months.ResultsPOD occurred in 8/46 TELF patients (17.4%) versus 1/54 ICELF patients (1.9%; p=0.011, OR=11.16), corresponding to an 89% relative risk reduction (NNT=6.4). Functional outcomes were equivalent at 12 months (MacNab excellent+good: 67.4% vs 70.4%, p=0.376). Within the TELF group, vertebral rotation was significantly higher in POD patients (19.2°±4.7° vs 12.2°±4.3°, p=0.001). ROC analysis identified a 15° threshold (AUC=0.870, sensitivity 88%, specificity 74%).ConclusionsICELF is associated with substantially lower POD rates compared to TELF in degenerative lumbar deformity, with equivalent functional outcomes. Vertebral rotation appears to be a specific, measurable risk modifier for POD in the transforaminal approach, suggesting its role in approach selection.
