Serum biomarkers in patients with ossification of the posterior longitudinal ligament (OPLL): Inflammation in OPLL [PDF]

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.

Baseline characteristics, perioperative complications, and 1-year outcomes in cervical OPLL versus cervical spondylotic myelopathy: a multicenter retrospective cohort study [PDF]

North American Spine Society Journal
: Background: Cervical ossification of the posterior longitudinal ligament (OPLL) is an important cause of degenerative cervical myelopathy. Unlike cervical spondylotic myelopathy (CSM), OPLL has been increasingly recognized as a distinct phenotype with

Correlation Between the Severity of Multifidus Fatty Degeneration and the Size of Ossification of Posterior Longitudinal Ligament at Each Spinal Level [PDF]

Neurospine, 2023
Objective This study aimed to investigate the correlation between ossification of the posterior longitudinal ligament (OPLL) size and multifidus fatty degeneration (MFD), hypothesizing that larger OPLL sizes are associated with worse MFD.

Genetic Odyssey to Ossification of the Posterior Longitudinal Ligament in the Cervical Spine: A Systematic Review [PDF]

Neurospine, 2022
Despite numerous studies, the pathogenesis of ossification of the posterior longitudinal ligament (OPLL) is still unclear. Previous genetic studies proposed variations in genes related to bone and collagen as a cause of OPLL.

Sacroiliac Joint Variation in Patients With Ossification of the Posterior Longitudinal Ligament

Global Spine Journal, 2023
Study Design: Retrospective Cohort Study. Objectives: Ossification of the posterior longitudinal ligament (OPLL) reveals heterotopic ossification in the spinal ligament. OPLL also tends to ossify ligaments and entheses throughout the body.

Strong relationship between dyslipidemia and the ectopic ossification of the spinal ligaments

Scientific Reports, 2022
Obesity and metabolic disturbances are prevalent in ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF); however, the involvement of dyslipidemia (DL) in OPLL/OLF remains uncertain.

Association Between Deep Posterior Cervical Paraspinal Muscle Morphology and Clinical Features in Patients With Cervical Ossification of the Posterior Longitudinal Ligament

Global Spine Journal, 2023
Study Design: A retrospective observational study. Objective: To clarify the association of the paraspinal muscle area and composition with clinical features in patients with cervical ossification of the posterior longitudinal ligament (OPLL).
