Cervical Myelopathy Ossification of the Posterior Longitudinal Ligament and DISH

Cervical Myelopathy Ossification of the Posterior Longitudinal Ligament and Diffuse Idiopathic Skeletal Hyperostosis: problems in investigation
Annals of the Rheumatic Diseases 1987;46:166-168;
I D Griffiths and T P Fitzjohn
This report describes a patient presenting with a spastic quadriplegia who was found to have both diffuse idiopathic skeletal hyperostosis (DISH) and ossification of the posterior longitudinal ligament (OPLL) in the cervical spine. There was a dramatic worsening of his symptoms during a myelogram examination of the neck. It is suggested that computed tomographic imaging of the neck is the preferred investigative procedure if OPLL is suspected as a cause of cervical myelopathy.

Diffuse Idiopathic Skeletal Hyperostosis eMedicine Radiology

Paraspinal ligaments undergo degeneration, secondary to attrition, and often ossify. This condition is broadly termed spinal enthesopathy. Physicians recognize 3 syndromes associated with this phenomenon, including (1) Forestier disease (most common; involving anterior longitudinal ligaments) and a more diffuse variant (exhibiting additional extra-axial features) that is termed diffuse idiopathic skeletal hyperostosis (DISH), (2) ossification of the posterior longitudinal ligament (OPLL), and (3) ossification of the vertebral arch ligaments (OVAL). Clinically, DISH is often referred to as senile ankylosing spondylitis because of similarities in appearance between these two conditions, despite the differing ages of onset.

Ossification of the posterior longitudinal ligament in three geographically and genetically different populations of ankylosing spondylitis and other spondyloarthropathies
CONCLUSIONSThe prevalence of OPLL in AS and SpA is higher than previously recognised and seems to be associated with variables identifying more severe axial disease.
