黄韧带骨化危险因素研究进展

Research Progress on Risk Factors of Ossification of Ligamentum Flavum

摘要: 黄韧带骨化(ossification of the ligamentum flavum, OLF)是导致胸腰椎椎管狭窄的重要病因，以往由胸腰椎黄韧带骨化所致胸腰椎椎管狭窄的病例并不多见。然而，随着中国居民健康意识及影像学技术的发展，黄韧带骨化所致椎管狭窄的病例越来越多的被发现。黄韧带骨化可合并硬脊膜粘连，因而增加相关手术风险及术后并发症的可能。梳理阐明黄韧带骨化的危险因素，对认识此种疾病并拓展新的诊疗思路至关重要，故本文对韧带骨化的高危因素进行综述。

Abstract: Ossification of the ligamentum flavum is an important cause of thoracolumbar spinal stenosis. In the past, the cases of thoracolumbar spinal stenosis caused by ossification of the ligamentum flavum were rare. However, with the development of Chinese residents’ health awareness and imaging technology, more and more cases of spinal stenosis caused by ossification of the ligamentum flavum have been found. Ossification of the ligamentum flavum can be associated with dural adhesions, thus increasing the risk of surgery and the possibility of postoperative complications. It is very im-portant to clarify the risk factors of ligamentum flavum ossification for understanding this disease and developing new diagnosis and treatment ideas, so this paper summarizes the high risk factors of ligamentum flavum ossification.
