Posttraumatic Spinal Cord Tethering and Syringomyelia: A Retrospective Investigation of Patients With Progressive Disease and Surgical Revisions.
Article in International journal of spine surgery, 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
backgroundSpinal cord tethering and syringomyelia after trauma are well-known pathologies in patients suffering from spinal cord injury (SCI). In symptomatic cases, various surgical options are available, but untethering and expansion duraplasty is the currently preferred treatment strategy. However, patient outcomes are usually limited by rather high rates of surgical revisions. The aim of the present study was to identify risk factors in SCI patients who underwent multiple surgeries for symptomatic spinal cord tethering and syringomyelia.
methodsWe retrospectively investigated 25 patients who received at least 2 untethering surgeries of the spinal cord. All patients were treated by untethering and expansion duraplasty and/or clinically followed between 2012 and 2022 at the Swiss Paraplegic Center.
resultsA higher location of SCI correlates with a more rapid development of symptomatic spinal cord retethering in need of surgical revision (
conclusionsRevision surgery in posttraumatic spinal cord tethering and syringomyelia patients is associated with the location of SCI and the extent of spinal cord tethering. It appears that chronic inflammatory conditions might play an important role in promoting spinal cord retethering and thus warrant further investigation. CLINICAL RELEVANCE: SCI patients with chronic inflammatory conditions and SCI at upper levels should be clinically monitored more carefully as they appear to be more susceptible to progressive forms of posttraumatic spinal cord tethering and syringomyelia.
