Expansive Laminoplasty for Multilevel Cervical OPLL

Journal of Spinal Disorders, 1997
Expansive laminoplasty is a new technique for the management of cervical ossification of the posterior longitudinal ligament (OPLL). Twenty patients were followed up for an average 3-year period. Follow-up examinations were performed every 3 months and at 1-year intervals.

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.

Metabolomics Analysis of OPLL Patients

2020
Metabolomics is one of the “omics” technologies and is a comprehensive analysis of small molecule metabolites. The metabolomics is located at the downstream end of “omics” research; therefore, this research platform is most closely related to phenotype among other “omics” research.

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.

Diagnosis of OPLL and OYL: Overview

2007
The radiographic diagnosis of ossifi cation of the posterior longitudinal ligament (OPLL) is not diffi cult once a physician understands the disease entity in question. However, the diagnostic workup of OPLL is not simple. Depending on the condition of the patient, a functional assessment—such as evaluation of neurological symptoms, prediction of the ...

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 ...
