Extraordinary positional cervical spinal cord compression in extension position as a rare cause of postoperative progressive myelopathy after cervical posterior laminoplasty detected using the extension/flexion positional CT myelography: one case after laminectomy following failure of a single-door laminoplasty/one case after double-door laminoplasty without interlaminar spacers.

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
purposePosterior cervical laminectomies and laminoplasties are common treatments for cervical spondylotic myelopathy. However, recent studies demonstrated that positional spinal cord compression occurred after cervical laminectomies and caused postoperative progressive myelopathy. Although there were no such reports after laminoplasties, we report two cases in which symptomatic extraordinary positional spinal cord compression occurred after laminoplasties in this paper.
methodsThis study included two patients who showed progressive myelopathy: one case after a laminectomy following failure of a single-door laminoplasty and one case after a double-door laminoplasty without interlaminar spacers.
resultsThe MRIs showed mild cord compression in the neutral position in both cases. However, the patients could not extend their necks, because it triggered severe neck pain and numbness. Therefore, the positional CT myelography (CTM) was taken in the flexion and extension positions, and it showed severe spinal cord compression only in the extension position. Posterior instrumented fusions were performed for both patients, which improved their symptoms.
conclusionsThis paper demonstrates that postoperative positional spinal cord compression during neck extension caused a progressive myelopathy even after laminoplasty. When myelopathy symptoms worsen after laminoplasties, we recommend positional CTM/MRI evaluation, even though there is no apparent cord compression in the neutral MRI.
