Defining limits of foramen magnum decompression in Chiari I malformation to prevent complications related to cerebellar migration: An anatomico-radiological study.

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
Background: Foramen magnum decompression (FMD) is the primary modality of treatment for symptomatic Chiari I malformation. However, the surgery is associated with cerebrospinal fluid (CSF) dynamic complications which may include non-improvement of symptoms, progression of syrinx, or cerebellar slump which are related to the size of decompression. Objective: The objective of the study was to define the limits of FMD to prevent CSF dynamic complications, including cerebellar ptosis. Materials and Methods: Anatomical relations of cerebellar tonsils and occipital bone were studied in 42 sagittal cut sections and 105 sagittal magnetic resonance imaging (MRI) sections. The limits of decompression were defined by our proposition of decompressing till the inferior semilunar fissure. In total, 27 patients underwent FMD and 21 were followed up. Results: Occipital bone in cut sections and MRI sections showed four configurations termed as single cusp, bicuspid, straight, and question-mark. Of these, straight and question-mark configurations were more commonly seen. Of the 21 patients who were followed up after FMD, all had good improvement with none developing features of CSF dynamic complications. Conclusion: The FMD surgery for Chiari I malformation should be performed with limits tailored to individual patients. Decompression should stop at the inferior semilunar fissure so as to prevent CSF dynamic complications, including cerebellar ptosis.
