Biportal Endoscopic Techniques for Severe Dural Ossification in Thoracic Ossification of the Ligamentum Flavum: Insights From Preoperative Imaging.
Article in Neurospine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveThis study evaluates surgical strategies based on preoperative computed tomography (CT) findings during unilateral biportal endoscopic (UBE) surgery for thoracic ossification of the ligamentum flavum (OLF) with dural ossification.
methodsThis retrospective study included patients undergoing posterior thoracic laminectomy via UBE surgery to treat symptomatic thoracic stenosis due to OLF. Clinical outcomes were assessed using visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) scores, alongside analyses of preoperative CT and intraoperative videos for dural ossification characteristics.
resultsA total of 34 patients participated, showing significant improvements in VAS and JOA scores postoperatively. All focal dural ossifications exhibiting the tram-track sign were effectively excised without significant dural defects. The circumferential floating technique was employed for cases with the bridge sign, whereas wide excision was warranted for those with the comma sign.
conclusionUBE surgery effectively manages progressive thoracic OLF associated with dural ossification. Preoperative CT imaging is essential for assessing dural involvement and guiding surgical techniques. Microscopic surgery is recommended for inexperienced surgeons requiring wide dural excision.
