History of Research on Ossification of the Posterior Longitudinal Ligament

  • Takashi Sakou

Abstract

Ossification of the posterior longitudinal ligament (OPLL) has been widely recognized in recent years. However, this disease does not have a long history. OPLL was first described by Key [1] in 1838 as a disease that causes paraplegia. However, it then went without notice for a long time. Oppenheimer [2] reported 18 cases with calcification or ossification of the anterior and posterior longitudinal ligaments. However, most of these were ossification of the anterior longitudinal ligament. He did not notice the clinical significance of OPLL because he did not think that it caused neurological symptoms.
