title: [Calcification and ossification of the posterior and longitudinal ligament of the cervical spine(author's transl)].
abstract: Three patients with calcification or ossification of the posterior longitudinal ligament of the cervical spine are described.  This abnormality is very common in Japan.  Descriptions from non-Japanese sources vary considerably.  The practical significance of this abnormality consists of narrowing of the spinal canal, which may result in a myelopathy.  Two of our patients are Chinese, the third was a white Dutchman.
