Summary
Ossification of the ligamentum flavum (OLF) was found in 35.4% of patients in Saudi Arabia. This spinal condition was usually asymptomatic and not a cause of myelopathy in the study group.
Area of Science:
- Neurosurgery
- Radiology
- Orthopedics
Background:
- Ossification of the ligamentum flavum (OLF) is a pathological hardening of the ligamentum flavum, a spinal ligament.
- Its prevalence and clinical significance, particularly in the Middle East, remain incompletely understood.
Purpose of the Study:
- To determine the prevalence, characteristics, and associated spinal diseases of OLF.
- To report the first findings of OLF in the Middle East population.
Main Methods:
- Retrospective analysis of 82 patients who underwent spinal CT scans over an 8-month period.
- Evaluation of age, sex, OLF presence, site, type (linear or nodular), and associated spinal pathologies.
Main Results:
- OLF was present in 35.4% of patients, predominantly as the linear type (74.5%).
- OLF occurred at single (51%) and multiple (41%) levels, associated with other spinal diseases in 81% of affected levels.
- No cases of OLF causing myelopathy were observed.
Conclusions:
- OLF is relatively common in this Saudi Arabian cohort, typically presenting as asymptomatic linear ossification.
- This study provides initial data on OLF from the Middle East, highlighting its generally benign clinical presentation.
