Percutaneous ultrasonographic evaluation of the spinal cord after cervical laminoplasty: time-dependent changes.
Article in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2018. 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
purposeThe first purpose of this study is to confirm whether the spinal cord and the surrounding tissues can be visualized clearly after laminoplasty using percutaneous ultrasonography. And second purpose is to evaluate the changes in the status of the spinal cord over time.
methodsFifty patients who underwent cervical laminoplasty with suture anchors were evaluated using intraoperative ultrasonography and postoperative (1 week, 2 weeks, 3 months, 6 months, and 1 year) percutaneous ultrasonography. We classified the decompression status of the spinal cord into three grades and the pattern of the spinal cord pulsation into six categories. Clinical outcomes were evaluated using the Japanese Orthopaedic Association Score for cervical myelopathy, and the recovery rate was calculated.
resultsIn all cases and all periods, we could observe the status of the spinal cord using percutaneous ultrasonography after cervical laminoplasty. The decompression status of the spinal cord improved until 3 months postoperatively, and the clinical outcomes improved up to 6 months postoperatively. Although the pulsation pattern of the spinal cord varied in each individual and in each period, spinal pulsation itself was observed in all cases and all periods, except one, when an epidural hematoma caused quadriplegia and a revision surgery was needed. Decompression status and pulsation pattern of the spinal cord were not associated with clinical outcomes as far as pulsation was observed.
conclusionsPercutaneous ultrasonography was very useful method to evaluate the postoperative status of the spinal cord, particularly in the diagnosis of the postoperative epidural hematoma. These slides can be retrieved under Electronic Supplementary Material.
