Ossification of the posterior longitudinal ligament

Clinical Neurology and Neurosurgery, 1985
Two non-Japanese patients with ossification of the cervical posterior longitudinal ligament were described. This abnormality is very common in Japan, but rare in non-Japanese people. The reason is unknown. Although the disease appears to be generally asymptomatic, it can cause a myelopathy.

Ossification of posterior longitudinal ligament and fluorosis

Neurology India, 2018
Ossification of posterior longitudinal ligament (OPLL) is a progressive disease that causes spinal canal compromise and serious neurological sequelae in advanced cases. The incidence of OPLL in the Asiatic population is 2%-3%, but the incidence is more in the background of fluorosis.

Ossification of the posterior cervical longitudinal ligament

Acta Neurochirurgica, 1992
Forty patients with cervical myelopathy due to OPLL (Ossification of the Posterior Longitudinal Ligament) of the cervical spine were studied. According to Abe's or Yamamoto's classification, 12 of them had a 50% decrease in the cross-sectional area of the spinal canal.

Ossification of the Posterior Longitudinal Ligament

Spine, 1995
This study analyzed the mode of inheritance of ossification of the posterior longitudinal ligament (OPLL) from the pedigree of a family.The results were correlated to provide a new mode of inheritance of OPLL.Although a nation-wide multicenter survey of OPLL has been carried out in 347 subjects and 1030 relatives in Japan since 1981, no parental ...

Ossification of the Posterior Longitudinal Ligament of the Spine

Clinical Orthopaedics and Related Research, 1984
Ossification of the posterior longitudinal ligament of the spine (OPLL) is a newly recognized entity. As the incidence of this disease was exceptionally high in Japan, the Japanese Ministry of Public Health and Welfare instituted a special commission for the investigation of this perplexing disease; since 1975 this committee has performed an intensive ...

Clinical calcium, 2009
Ossification of the longitudinal ligament in the spine is a disorder of unknown cause characterized by ectopic ossification. In the animal models of spinal hyperostosis, the vertebral ligament is gradually replaced by bony tissue forming an osseous bridge around enthesis, and a high turnover osteopenia occurs after the maturation in the trabecular bone

[Ossification of posterior longitudinal ligament].

Clinical calcium, 2014
Ossification of posterior longitudinal ligament (OPLL) is a hyperostotic disease of the spine associated with myelopathy which is occurred by an anterior compression to the spinal cord. OPLL was first reported by Key GA in 1838, and was previously considered specific to east Asian people, especially Japanese.

Ossification of the Posterior Longitudinal Ligament

2018
Ossification of the posterior longitudinal ligament (OPLL) may occur in patients presenting with cervical myelopathy or cervical radiculopathy. Mild trauma may aggravate symptoms, resulting in a rapid progression of cervical myelopathy. Recognition is key and utilization of computed tomography is the preferred imaging modality for diagnosing OPLL ...
