摘要

Purpose

Ossification of ligament flavum (OLF), a prevalent cause of thoracic myelopathy, continues to present significant challenges for clinicians. While recent studies have illuminated various pathogenic molecular cascades associated with OLF. Comprehensive review of the underlying signaling pathways involved in its development remains absent from the literature. This study aims to synthesize and critically discuss the current evidence, providing a thorough overview of the progress made in the understanding OLF pathogenesis.

Methods

A comprehensive literature search was conducted using PubMed, Medline, Web of Science, ChiCTR.org.cn, and ClinicalTrials.gov databases to identify studies investigating the mechanisms involved in the development of OLF. The selected studies were categorized based on the type of mechanism explored. Initialing factors were summarized in tables and figures, and the related content were discussed systematically discussed.

Results

The mechanisms underlying OLF formation primarily involve genetic background and modification, mechanical stress, osteogenesis-related proteins, non-coding RibonucleicAcid (RNA) and metabolism. However, clinical trials reporting the translational application of these existing mechanisms were scarce.

Conclusions

The formation and development of OLF are multi-factorial, and the underlying mechanisms have been preliminarily elucidated. Future research should focus on the clinical application of these mechanisms. This review may provide a theoretical basis for the development of therapeutic agents and offer new perspectives further studies on OLF.
