Diagnosis of OPLL and OLF: Overview

2020
Recent progress in image diagnosis technology enables us to detect numerous new findings for the diagnosis of ossification of the posterior longitudinal ligament (OPLL) and ossification of the ligamentum flavum (OLF). In most cases of cervical OPLL and thoracic OPLL/OLF, not only static compression, but also dynamic factors contribute to the ...

Postoperative Instability of Cervical OPLL and Cervical Radiculomyelopathy

Spine, 1989
The presence of cervical spine instability with respect to preoperative and postoperative changes in angular, horizontal, and rotational displacement of the vertebral body were studied. With the anterior approach, the instability in the remaining unfused segments, and their relation to the kyphotic or lordotic fused segment were studied.

Genetic Susceptibility to OPLL

2007
It is our consensus that elucidation of the genetic factors involved in OPLL is a key issue for fully understanding the pathophysiology of OPLL in the search for future therapeutic methods. For a number of years efforts have been made to identify genes responsible for OPLL.

Corpectomy: Floating Method for OPLL

2019
Anterior cervical corpectomy and fusion is an effective procedure for the treatment of ossification of the posterior longitudinal ligament (OPLL) because it provides direct decompression to the spinal cord and stabilizes the involved segments. The anterior floating method thins the ossification and disconnects it from the surrounding bony tissues ...

Clinical Manifestation of Cervical OPLL

2007
Ossifi cation of the posterior longitudinal ligament (OPLL), which is most frequently found at the cervical spine, causes several symptoms. OPLL can be detected on lateral plain radiographs, and the diagnosis and morphological details of cervical OPLL have been clearly demonstrated by magnetic resonance imaging (MRI) and computed tomography (CT).

Clinical Manifestation of Cervical OPLL

2020
The clinical symptoms and signs caused by cervical ossification of the posterior longitudinal ligament (OPLL) are divided into three categories: (1) cervical myelopathy or spinal cord injury with motor and sensory disturbance of the upper and lower limbs, spasticity, and bladder dysfunction; (2) cervical radiculopathy with pain and motor and sensory ...

Diagnostic Imaging of Thoracic OPLL and OLF

2020
The most standard diagnostic imaging modality for ossification of the posterior longitudinal ligament of the spine (OPLL) and ossification of the ligamentum flavum (OLF) is a plain radiography; however, standard plain radiography is not an adequate for diagnosis of thoracic OPLL (T-OPLL) and thoracic OLF (T-OLF) because of the characteristic anatomy of
