Ligamentum flavum hematomas: Why does it mostly occur in old Asian males? Interesting point of reported cases: Review and case report

Abstract

Hematoma of the ligamentum flavum (LF) is a rare cause of neural compression and sciatica. Currently, the etiology and epidemiological characteristics of ligamentum flavum hematoma (LFH) are unknown and epidemiological investigations using rewieving of reported cases have not been performed. We report the case of a 63-year-old man with a LFH compressing the spinal canal at the left L2–L3 level, rewieved relevant literature. In Medline research, wefound a total of 50 reported cases with LFHs, and the interesting point of these cases were analyzed. Many of cases were old males. Interestingly, 39 of the 50 cases were reported from Asian countries. The ages of 42 patients could be verified. The youngest age was 45 years, oldest age was 81 years, and mean age was 66.07 years. Thirty-three out of these 42 patients (78.53%) were older than 60 years. An important aspect of the present review is to bring attention for occurrence in older Asian males. With an increasing number of elderly people in the general population, there is a need to investigate risk factors such as sexual gender, age, and geographic location for LFH.

Sudden death and cervical spine: A new contribution to pathogenesis for sudden death in critical care unit from subarachnoid hemorrhage; first report – An experimental study

“…The recognition of this fact is important, if indeed one is the first to report something and that something is of value. [ 18 27 28 29 ] Given the high frequency of sudden death following SAH, it is important for intensive care physicians to become familiar with their pathophysiology, allowing for more prompt and appropriate treatment of SAH patients. In some contexts, red flags mean that something important needs to be brought to immediate attention.…”

First report of perforation of ligamentum flavum by sequestrated lumbar intervertebral disc

“…One of this structures is LF from the axis to sacrum extending downward from the lamina of the respective anatomic segment. [ 22 ] The LF is thick and short and is symmetrical on both the left and right sides. On each side, the LF divides into a medial portion and lateral portion.…”

“…At each level, the LF extends laterally to blend with the facet capsule. [ 22 ] The ligamenta are thickest at the lumbar levels. However, our present case indicates that lateral part of flavum may not be as strong as medial part.…”

Inequality in leg length is important for the understanding of the pathophysiology of lumbar disc herniation

“…At present, neurosurgical practice is confronted by an explosion of technology. [ 20 21 22 ] In the 1990s, the advent of MRI and the progressive increase in definition of this modality of imaging have considerably contributed to the knowledge of spinal disorders. With the time and in parallel to the technological advancement, new and more complex spine procedures were performed.…”
