title: [Ossification of the posterior longitudinal ligament (OPLL) and the ligamentum flavum (OLF)].
abstract: The adult population is frequently sustained with ossification of the posterior longitudinal ligament (OPLL) and/or the ligamentum flavum (OLF) of the spine and the diseases may subsequently result is serious spinal cord insult with profound paralysis of the extremities. These pathologies are genetically denoted metaplasia of the elastic fibers of the ligament with consequent ectopic ossification process. The spinal cord is chronically compressed and will result in profound motor paralysis with sensory deficit. Both diseases are well imaged on CT and MRI, showing a various magnitude of spinal cord compression.
