Characteristics of the cervical spine and cervical cord injuries in older adults with cervical ossification of the posterior longitudinal ligament

Scientific Reports, 2023
Although the incidence of cervical spinal cord injury (CSCI) with ossification of the posterior longitudinal ligament (OPLL) has increased in older adults, its etiology and neurological outcomes remain unknown.

DLX5 regulates the osteogenic differentiation of spinal ligaments cells derived from ossification of the posterior longitudinal ligament patients via NOTCH signaling

JOR Spine, 2023
Background Ossification of the posterior longitudinal ligaments (OPLL) is common disorder characterized by heterotopic ossification of the spinal ligaments. Mechanical stimulation (MS) plays an important role in OPLL.

Comparative Study of the Cytokine Profiles of Serum and Tissues from Patients with the Ossification of the Posterior Longitudinal Ligament

Biomedicines, 2023
Background: The ossification of the posterior longitudinal ligament (OPLL) is one of the contributing factors leading to severe cervical spondylotic myelopathy (CSM). The mechanism causing ossification is still unclear.

MRI of cervical OPLL.

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.

Diffuse idiopathic skeletal hyperostosis (DISH) with ossification of the posterior longitudinal ligament (OPLL) in the cervical spine without neurological deficit – A Case report

Annals of Medicine and Surgery, 2020
Introduction Diffuse idiopathic skeletal hyperostosis (DISH), or Forestier disease, is a condition characterized by calcification and ossification of ligaments and enthuses (ligament and tendon insertion sites), which mainly affect the vertebral column ...

Distribution of ossified spinal lesions in patients with severe ossification of the posterior longitudinal ligament and prediction of ossification at each segment based on the cervical OP index classification: a multicenter study (JOSL CT study)

BMC Musculoskeletal Disorders, 2018
Background In patients with ossification of the posterior longitudinal ligament (OPLL) in the cervical spine, it is well known that the thoracic ossified lesions often coexist with the cervical lesions and can cause severe myelopathy.

The corelation in the progression of ossification between the OPLL and the OALL in cervical OPLL patients.

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%
