Contemporary views on the ossification of the ligamenta flava.
The ligamenta flava, together with the vertebral lamina, form the posterior wall of the spinal canal. Since they are located immediately adjacent to the nerve structures of the spinal cord, every pathology that involves hypertrophy produces neurological disturbances as a result. One of the most common reasons for hypertrophy of the ligamenta flava is heterotopic ossification. The main regions o...
متن کاملRadiologic imaging of symptomatic ligamentum flavum thickening with and without ossification.
Thickening of the ligamenta flava with and without ossification in the thoracic and lumbar regions is a frequent finding on CT scanning; however, it is not widely appreciated as a possible primary cause of compressive cord, cauda equina, and nerve-root symptoms. We present observations from a series of seven patients whose symptoms were caused exclusively or largely by thickened ligamenta flava...
متن کاملHistological Changes of Ligamenta Flava in Lumbar Disc Herniation and Spinal Canal Stenosis
Samples of ligamenta flava were obtained after surgical operations from 50 patients with a lumbar disc herniation, another 50 patients with a lumbar canal stenosis, and 25 patients with spinal fractures who were used as control group. Ligamenta flava from control patients aged below 46 years consisted of large elastic fibers, thin bundles of collagen fibers, and few spindle-shaped fibroblast ce...
متن کاملComputed tomographic demonstration of calcification of the ligamenta flava of the lumbosacral spine in ankylosing spondylitis.
An axial computed tomographic (CT) scan of the lumbosacral regions was performed in 65 patients. The patient population was divided into two groups. The first (control) group included 40 elderly patients without calcification of the ligamenta flava. The second group included 25 patients with ankylosing spondylitis. More than 90% of those in the second group showed calcified lumbosacral ligament...
متن کاملEffect of ligamenta flava hypertrophy on lumbar disc herniation with contralateral symptoms and signs: a clinical and morphometric study
INTRODUCTION The purpose of this study was to determine whether ligamentum flavum hypertrophy among disc herniated patients causes contralateral pain symptoms. For this reason we measured the thickness of the ligament in disc herniated patients with ipsilateral or contralateral symptoms. MATERIAL AND METHODS Two hundred disc herniated patients with ipsilateral symptoms as group I were compare...
