In ankylosing spondylitis there's chronic inflammation of the intervertebral joints and the facet joints of the spine.

患有强直性脊柱炎时，椎间盘和关节突关节内存在炎症。

In addition to the intervertebral discs, each vertebra has joints called facet joints with the vertebra above and the vertebra below, one on each side.

除了椎间盘，椎骨之间还有一种称为关节突关节的连结，在椎骨前后侧方各有一个。

Over time, the inflammation destroys the intervertebral joints, as well as the facet joints, and the sacroiliac joints, and fibroblasts replace the destroyed joint with fibrin.

随着时间推移，炎症会破坏椎间盘、关节突关节和骶髂关节，而成纤维细胞会用纤维蛋白取代被破坏的关节组织。
