Summary
Ossification of the posterior longitudinal ligament (OPLL) presents in varied forms, with linear OPLL common in the cervical spine and curved OPLL more frequent in the lumbar spine. This study details three distinct X-ray identified types in 21 patients.
Area of Science:
- Orthopedics
- Radiology
- Neurology
Context:
- Ossification of the posterior longitudinal ligament (OPLL) is a condition affecting the spine.
- Patients presented with OPLL secondary to ischemic myelopathy, cervical spine trauma, or vertebral osteochondrosis.
Purpose:
- To define and specify X-ray signs of three types of ossification of the posterior longitudinal ligament.
- To analyze the distribution of ossification types across spinal regions.
Summary:
- Twenty-one patients (37-83 years old) with OPLL were studied.
- Three types of OPLL were identified: linear, curved, and mixed.
- Linear OPLL was more prevalent in the cervical spine, while curved OPLL was more common in the lumbar spine.
Impact:
- Provides a classification of OPLL based on radiographic findings.
- Highlights regional variations in OPLL presentation.
- Aids in understanding OPLL for improved diagnosis and treatment planning.
