Ossified Ligamentum Flavum causing Cervical Myelopathy
Ossification of the ligamentum flavum (OLF) causing compressive cervical myelopathy or radiculopathy is rare. A 50-year-old male was admitted for progressive hypesthesia and paresthesia of both hands and a gradually worsening gait. MRI and CT scans demonstrated ossification of the left ligamentum flavum with dural sac and cord compression at the C5-6 level. The ossified ligamentum flavum was re...
متن کاملIsolated Proximal thoracic ossified ligamentum Flavum Causing Paraparesis in a Caucasian: A Case report and review of the literature
Ossification of the ligamentum flavum is a pathologic condition that affects the yellow ligaments mostly in male adults between fifty to sixty years of age. Ossification is more common in the thoracic spine causing slowly progressive myeloradiculopathy. In fact, OLF is so common in East Asian countries that is regarded as a frequent aging pathology in the people of this region (3,10-15,21,22,31...
متن کاملOssification of the Ligamentum Flavum
Ossification of the ligamentum flavum is a rare cause of thoracic myelopathy. It develops in East Asians more frequently than in people from other areas. The exact pathophysiology has not been elucidated yet; however, it largely depends on biomechanical alterations, especially changes in the tensile force. Because the spinal cord is compressed from the posterior side, the first and most common ...
متن کاملLigamentum flavum hematoma in the lumbar spine.
A patient who presented with symptoms suggestive of nerve root compression secondary to an extradural mass was found to have a hematoma in the ligamentum flavum. Pathological examination of surgical specimens revealed an old hemorrhage, and hemosiderin deposits around organized granulation tissue within the ligamentum flavum. Vessels within the ligamentum flavum had, presumably, ruptured during...
متن کاملPhenotypic Characterization of Ligamentum Flavum Cells from Patients with Ossification of Ligamentum Flavum
PURPOSE The objective of this study was to determine the phenotypic characterization of ligamentum flavum cells from patients with ossification of the ligamentum flavum (OLF). MATERIALS AND METHODS Ligamentum flavum tissues were harvested from OLF and non-OLF patients during surgery. OLF and non-OLF cells were isolated from explant cultures. Cultured cells were analyzed using immunofluorescen...
