Ossification of the posterior longitudinal ligament
Clinical Neurology and Neurosurgery
|January 1, 1985
Summary
Ossification of the cervical posterior longitudinal ligament, common in Japan, is rare in non-Japanese individuals. This condition, though often asymptomatic, can lead to myelopathy, impacting spinal cord function.
Area of Science:
- Neurology
- Orthopedics
- Radiology
Background:
- Ossification of the cervical posterior longitudinal ligament (OPLL) is a prevalent condition in Japan.
- OPLL is infrequently observed in non-Japanese populations, with the underlying reasons remaining unclear.
Observation:
- The study details two non-Japanese patients diagnosed with OPLL.
- Clinical presentation, diagnostic imaging (X-rays), and histopathological findings are presented.
Findings:
- While OPLL is frequently asymptomatic, it carries the potential to cause cervical myelopathy.
- A notable similarity was observed between the vascular patterns in OPLL and lumbar spine cases presenting with intermittent neurogenic claudication.
Implications:
- Highlights the rare occurrence of OPLL in non-Japanese individuals, prompting further etiological research.
- Underscores the diagnostic importance of imaging and histopathology for OPLL.
- Suggests potential shared pathomechanisms or diagnostic considerations with lumbar spine conditions.
