Quadriplegia associated with narrow cervical canal, ligamentous calcification and ankylosing hyperostosis.
The occurrence of three pathological entities of the cervical spine--ankylosing hyperostosis, calcification of the posterior longitudinal ligament, congenitally narrowed cervical canal--in a single patient is reported. This combination of pathology led to a severely narrowed cervical canal and a spine with abnormal mobility at non-fused levels. Minor trauma to the patient resulted in permanent quadriplegia.
