腰椎间盘膨隆与间盘疝的相关性研究

The relation of bulging disc and herniated disc

为研究腰椎间盘膨隆与间盘疝的相关性，应用ＣＴ和病理学技术观察了２３例尸体中１５个膨隆间盘，并分析了３８６例间盘退行性变的ＣＴ影像表现。在膨隆间盘的切片上见到纤维环的横行、环形或（和）放射性撕裂及髓核碎裂；在临床病例的ＣＴ影像上发现了同一间盘上膨隆和疝并存的现象（间盘膨隆伴疝）；并探讨了它与间盘膨隆和间盘疝的相互关系，认为间盘膨隆伴疝应列为椎间盘退行性病变的类型之一。

ifteen lumbar bulging discs from 23 cadaverswere examined by CT and histological technique, and386 degenerating lesions in lumbar discs were studied ifrt has any relationship with degenerative diseases of in-tervertebral discs. Histologically, trasverse, concentricor/and radial tears were found in some anulus fibrosusof bulging discs. Clinically, the coexistence of bulgingand hernia was noticed in a lesioned disc, we named itas “bulging and herniated disc”, and the relation ofwhich with bulging disc and herniated disc was disc-cussed. This finding will change a well-known opinionthat hernia would not occur in a bulging disc. Herebulging and herniated disc would reasonably be consid-ered as one of degeneerative diseases of intervertebraldiscs.
