The relationship between OPLL and metabolic disorders. [PDF]
Bone ResAbstract Ossification of the posterior longitudinal ligament (OPLL) is a degenerative disease characterized by progressive ectopic bone formation process, which can lead to severe neurological impairments and reduced quality of life.

PLOS ONE, 2017 Ossification of the posterior longitudinal ligament (OPLL) is characterized by replacement of ligamentous tissue by ectopic new bone formation. OPLL causes narrowing of the spinal canal, resulting in neurological impairment. However, the pathogenesis of OPLL has not been fully elucidated. We investigated whether inflammation occurs in OPLL or not using

Spine, 2015 Retrospective study.To evaluate the usefulness of 3-dimensional (3D) measurement of ossification of the posterior longitudinal ligament (OPLL), and identify the reliability of a novel 3D method of measurement.OPLL is not a 2-dimensional (2D) disease, but rather a 3D disease. Therefore, conventional measurement of parameters using radiography may not be

Analysis of progression of cervical OPLL using computerized tomography: typical sign of maturation of OPLL mass [PDF]
Journal of Neurosurgery: Spine, 2015 OBJECT The progression of cervical ossification of the posterior longitudinal ligament (OPLL) can lead to increase in the size of the OPLL mass and aggravation of neurological symptoms. In the present study, the authors aimed to analyze the progression of cervical OPLL by using CT imaging, elucidate the morphology of OPLL masses, and evaluate the ...

Orthopedics & Traumatology, 1990 MRI findings of 41 patients with cervical OPLL were investigated. The 41 patients consisted of 28 males and 13 females with a mean age of 59 years (range, from 43 to 80 years). According to the morphological classification of OPLL, 12 patients had continuous type, 13 had mixed type, and 16 had segmental type.

Orthopedics & Traumatology, 1989 We studied radiologically the progression of ossification between the OPLL and the OALL in 52 cases of cervical OPLL patients who had been treated conservatively. Remarkable progression of the OALL was seen in 27 of 52 cases (52%). Considering corelation between the type of OPLL and the progression of OALL, remarkable progression of OALL was seen in 80%

A case of cervical OPLL and DISH mimicking stroke
Surgical Neurology International, 2022 Background: Ossification of the posterior longitudinal ligament (OPLL) is a progressive disorder that mostly involves the cervical spine. It is more prevalent in East Asian countries. Patients typically present with the gradual onset of myelopathy, while about 5% show rapid progression.

Study for the hereditary trait of OPLL
Orthopedics & Traumatology, 1984 Hereditary trait of OPLL was studied radiographycally in twenty-two patients suffering from this disorder in the cervical spine. This study included ninety-nine persons of twenty-two families. The familial incidence of OPLL was found in nine families of twelve persons.

The HLA typing in OPLL families.
Orthopedics & Traumatology, 1988 The HLA typing in ten patients with ossification of the posterior longitudinal ligament (OPLL) in the cervical spine and their families was carried out to elucidate the genetic factor of OPLL onset. The HLA haplotypes were determined by segregation of the HLA phenotypes within a family. The results of the analysis of HLA haplotypes in the OPLL patients

MRI study of OPLL in cervical region.
Orthopedics & Traumatology, 1990 Diagnosis by MRI was analyzed in 15 patients with OPLL of the cervical region. As a result we found that MRI could diagnose OPLL in 9 of 15 patients (60%). This rate was inferior to those by plain radiographs (86.7%), tomogram (100%) and CT (100%).
