This is an overview of paravertebral ligamentous ossification based on our 5-year experience in ossification of posterior longitudinal ligament (109 cases) and ossification of ligamentum flavum (18 cases). Paravertebral ligamentous ossification is designated as the disorder caused by frequently coexisting ossification of paravertebral ligaments, DISH, OPLL, and OLF. The frequency of the occurrence of isolated ossification of PLL and OLF in Japan is still uncertain. DISH, which is not rare in Europe or North America, is frequently associated with ossification of the posterior aspect of the vertebral bodies, but it may be less symptomatic. The major cause of the probably higher incidence of symptomatic patients in Japan may be due to associated narrowing of the spinal canal.
这是基于我们在5年中对后纵韧带骨化（109例）和黄韧带骨化（18例）的经验所做的椎旁韧带骨化概述。椎旁韧带骨化被定义为由椎旁韧带、弥漫性特发性骨肥厚（DISH）、后纵韧带骨化（OPLL）和黄韧带骨化（OLF）频繁共存引起的病症。在日本，单纯的后纵韧带骨化和黄韧带骨化的发生频率仍不确定。DISH在欧洲或北美并不罕见，常与椎体后部骨化相关，但症状可能较轻。日本有症状患者发病率可能较高的主要原因可能是伴有椎管狭窄。
