Summary. Ossification: process of changing into a bone or bone-like substance. Posterior: anatomical term meaning “further back in position” Longitudinal: anatomical term that means “traveling long-ways” Ligament: soft tissue that connects and supports the bones of joints. Ossification of the posterior longitudinal ligament. Ossification of the posterior longitudinal ligament (OPLL) is typically an entity seen in patients of Asian descent, although it is seen in all ethnic groups. It is characterised by, as the name suggests, ossification of the posterior longitudina. Ossification of the posterior longitudinal ligament (OPLL) is a process of fibrosis, calcification, and ossification of the posterior longitudinal ligament of the spine, that may involve the spinal dura. Once considered a disorder unique to people of Asian heritage, it is now recognized as an uncommon disorder in a variety of.
28 Nov Ossification of the posterior longitudinal ligament (OPLL) is most commonly found in men, in the elderly, and in Asian patients. The disease can start with mild or no symptoms, but some patients progress slowly to develop symptoms of myelopathy. An accurate diagnosis through the use plain radiograph. (A) Sagittal computed tomography demonstrated a mixed type of ossification of the posterior longitudinal ligament (OPLL; continuous at C3–C4 and segmental at C5). (B) Sagittal T2 fat-suppressed sequence demonstrated cord signal change predominantly on the left side. The tiptoe walking (twy) mice has a natural occurrence of pathological ossification of spinal ligaments, such as ossification of the posterior longitudinal ligament, enlargement of the nucleus pulposus, regenerative proliferation of annulus fibrosus cartilaginous tissues.

OPLL is a calcification of the soft tissues that connect the spinal bones which results in a narrowing of the spinal canal and compression of the cervical spinal cord. The cause of OPLL is unclear at this point, but we know people of Asian heritage especially Japanese have a higher likelihood of developing.
