Investigation of the etiology and treatment of the condition has taught surgeons to see diseases of the spine and their surgical treatment in a new perspective. It was truly a surpr

Pathogenesis of Ossification of the Spinal Ligamentss (DISH; Resnick et al. 1975 [3]). However, unlike ASH and DISH, OPLL and OYL are characterized by the ossification of ligaments in the spinal canal and a high incidence of severe myelopathy, and are therefore often classified together as a distinct category, “ossification of the spinal ligaments” (OSL).

Pathology of Ossification of the Ligamentum Flavuming the narrowing of the spinal canal as seen by computed tomography (CT) and by magnetic resonance imaging (MRI), the CT scan provides information superior to that of MRI because it shows precisely the protruded ossification from the posterior to anterior aspect of the spinal canal [3-6].

Clinical Manifestation of Cervical Ossification of the Posterior Longitudinal Ligamented into four types: (1) segmental, (2) continuous, (3) mixed, and (4) localized [1,2]. The shape is also quite irregular. OPLL is one of the important factors in stenosis of the spinal canal, thus causing the spinal cord and the nerve roots to be entrapped or compressed in various ways.

Image Diagnosis of Cervical Ossification of the Posterior Longitudinal Ligamentle to visualize the detailed outline of the ossified or calcified mass. Be­cause OPLL often accompanies other ligamentous ossi­fication such as ossification of the ligamentum flavum, meticulous attention to both clinical and radiological findings is mandatory in determining the level of involvement [3].
