Ossification of the posterior longitudinal ligament (OPLL) is the new bone development and thickening of the posterior longitudinal ligament within the spinal canal. The clinical symptoms of OPLL appear mostly after 40 years of age. Patients complain of pain in the neck and the occipital area, and this is followed by paresthesia and weakness in the upper and lower extremities. We report a case with sudden tetraplegia after trauma because of cervical OPLL.
