Safety of Thermosensor Insertion in the Midline of the Spinal Canal Anterior to the Dura: A Cadaveric Study.
Article in Cardiovascular and interventional radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo evaluate the safety of the insertion of a blunt-tip thermosensor inside the anterior epidural space using the trans-osseous route in the dorsal spine and the double oblique trans-foraminal approach in the lumbar spine. MATERIALS AND
methodsA total of 10 attempts were made on a 91 years old human specimen. Thermosensors were inserted under fluoroscopic guidance in the anterior part of the spinal canal using various oblique angulations. Surgical dissection was then performed to identify the position of the thermosensor and look for any injury to the dural sac or the spinal cord/cauda equina.
resultsNine thermosensors could be deployed successfully in the anterior part of the spinal canal from Th8 to L5 while one attempt (L5 level) failed due to a technical issue on the coaxial needle. On anteroposterior projection, the tip of thermosensor relative to the midline was classified as centered in 5 cases, overcrossing in 3 cases and undercrossing in 1 case. At surgical dissection, the tip of the thermosensor was epidural posterior to the posterior longitudinal ligament in 8 cases and anterior to the longitudinal ligament in 1 case (the undercrossing case). There were 3 tears to the dura, all in the overcrossing group. There was no case of injury to the spinal cord/cauda equina.
conclusionInsertion of a thin blunt-tip thermosensor with optimal angulation leads to an epidural post-ligamentous position on the midline without damage to the dural sac. The blunt-tip did not prevent from dural tearing should the insertion overcross the midline.
